Free Bridge builder/Brain-teaser Game: The aim of the game is to build a solid bridge across a canyon within the allocated budget given. Once you complete the bridge, strange little creatures will try to cross the bridge, and will test it for you in full. Learning physics is made fun through this game, and it is a huge challenge getting the bridge structure right. The bridge building challenge increases significantly as you progress from levels 1 to 3!
You should only connect pieces from end to end only. Do not connect a supporting piece to the middle of some other piece (it is a weak link if you need to connect in the middle). Break the bridge piece into two parts, and only then connect the supporting piece to the junction. Use metal pieces only where the strength of wooden pieces would not be sufficient.
Use your mouse and keys to build the bridge: Click from one point to another to lay a piece of the bridge. Press the ESC button on your keyboard to deselect a piece. You can click on an existing piece to remove it or you can click on a section anchor point and press the Delete button to remove the section. Press the T key to see how your bridge holds up and if it can support its own weight. Press ESC to return to the construction phase when your testing is done and something needs to be fixed.
In Crush The Castle 2 (a medieval & physics-based game for teens), the Redvonian King has sent you, his trusty Siege Master, and Halgrim his finest mason, to bring together all of the greatest minds in the land to destroy Blutias’s Empire. Go forth, crush all of the castles of Blutias using the most powerful Trebuchet and ammunition. Start to play by clicking on New Game or People’s Empire (crush the castles built by other players). You can also build a castle on your own, by clicking on Castle Builder. The amount of Inhabitants eliminated, and your armor are shown at the bottom of the game screen, whereas your shots taken can be seen at the top of the game screen.
The further you get, the more new ammunition is offered to you by Halgrim and other clever people, such as Cormyn, the devlish engineer or Mauryl the Great, a hermit wizard. To choose which weapon to use, simply click on of the arrows located by the ammunition icon, and choose your weapon. The number of shots used is unlimited but if you crush a castle in one shot, you earn a Gold medal. Good luck!
Happy Builder is a challenging crane driving game for kids. Do you believe that you have the unique skills to do the job of a crane operator or do you fancy yourself as a civil engineer in your future career? In this Happy Builder game, you are in the "Builder of the Year" competition! As on every construction site, you should first become familiar with what you are going to build and only then should you start building.
It is all about the order when you are building something or you‘ll find yourself wasting time and energy. You cannot start from the roof before you have the walls. When picking up a block (a part of the structure), it must be picked up in such a way that it will be suitable to put in its place correctly. For example: You cannot put a dog's house sideways so it must be picked up the way it can be put bottom down first.
You have to consider the laws of physics (Earth gravity) too; A piece of structure that has no support on one side is simply going to fall or tumble down. Each piece must be carefully put in its place. Once it is in the correct position, a clock icon will appear indicating that the piece is in the right place and points will be counted (based on the speed you have put it in place). Once the clock finished turning, the piece of structure is „cemented in“ and cannot be moved. Only the correct blocks can be "cemented in“, as any other will stay loose if put in the incorrect position. Do not forget that the parts must be „pulled in“ one by one and cannot be put "through“ the others.
For example: You are building a wall with the doors. If the wall is built around the doors (the left and right side as well as the lintel above the doors ), you cannot put the doors in anymore as every possible direction is "blocked“. If that is the case, you have to start the construction of that site from scratch. To do so – click on „R“ button located at the top right corner and start building again. Once you have finished building one structure, you can proceed to the next one (which is more complex). A map is displayed and you can choose a new construction site by clicking on one of the orange cones. You can choose only the orange striped cones as grey ones are locked. They become unlocked as you gain experience and build more sites.
Structure pieces are brought by a conveyor on the right side. To pick up a structure piece, use your computer mouse to control the crane hook. Move it to the piece at the exact point where you wish to hook it up. Left Click and hold your mouse left button and start moving it with your mouse into the position it should be placed. Once in place, release the left mouse button and the piece is released. As in reality, every block has inertia – if you move it around very quickly and then stop suddenly, it will spin around on your crane hook.
Free Bridge builder/Brain-teaser Game: This is another, yet more challenging version of the bridge builder game, and it has more levels to get through. The objective of the game is to build a bridge across a canyon within the allocated budget. Learning physics is made fun through this game, and it is a huge challenge getting the structure right. Once your bridge is built, strange creatures will try to cross the bridge you built, and will test it in full. The bridge building challenge increases significantly as you progress from levels 1 to 3!
Use your mouse and keys to build the bridge: Click from one point to another to lay a piece of the bridge. Press ESC to deselect a piece. You can click on an existing piece to remove it or you can click on a section anchor point and press DELETE to remove the section. Press T to see how your bridge holds up and if it can support its own weight. Press ESC to return to the construction phase when your testing is done and something needs to be fixed.
You should only connect pieces from end to end only. Do not connect a supporting piece to the middle of some other piece (it is a weak link if you need to connect in the middle). Break the piece into two parts, and only then connect the supporting piece to the junction. Use metal pieces only where the strength of wooden pieces would not be sufficient. Have fun!
Pandemic 2 - In this online strategy game you play the role of an evil scientist trying to create a biological weapon. You are the one trying to create a virus, a parasite or bacteria with specific characteristics which in turn infects all inhabitants on Earth. You win the game if you achieve this. This is not an easy task as governments and hospitals are, at the same time, working hard to prevent the spread of disease and find a cure.
It’s your job to infect everyone in the world with your disease. You start with a disease that's very low on the radar which looks like a locally-spread flu. There are very few symptoms to indicate what sort of contraction this is, and most people do not recognize what trouble is coming to them. While keeping the long-term effects of the infection low enough, you can increase the spread of the infection without being taken seriously by governments. If you manage to infect 80% of the population so it has an annoying but inconsequential infection, you can put your evil plan to work – to increase the deadliness of the infection up to 11 times and wipe out life on the planet. This sure is one crazy scientist that you are role playing.
Chemikul is an online science/ chemistry-based game that will send you on an atomic mind-bender of confusion - as well as provide endless hours of enjoyment! With super-slick ambient graphics and simple acoustics, it’s a learning experience that anyone can enjoy. The goal is to create molecules using all of the atoms floating in the game screen. There are six types of atoms and they all have different amounts of “Valence” (combining power), ranging from 1 to 6 in strength.
Win the game by using up the Valence of each atom. You can see the Valence number of each atom beside it – Used Valence/Full Valence. You need to be as fast as possible. Once the bar at the top of the game screen runs out, you lose. This experience is sure to set off chemical reactions in your brain. Give it a go!
Play a tricky block-stacking construction game & physics-based puzzle that requires a deft problem-solving approach: Woodwork Builder: The City is a challenging, drag-and-drop construction game for older kids & teens where you must fill in an outlined area (on the screen) with a red block. This game also plays like a hidden crane operator simulation activity because the mouse control action and the movement and swing of the objects (blocks, beams and columns) very much feels like you are handling a crane jib control tool.
This game requires good visual awareness, analytical thinking and creative engineering skills, combined with steady mouse control and patience to carefully figure out the best way to create a firm structure or solid support tower that stays upright and provides a platform for your final (red) block to be placed.

The goal in this brain-teaser is to build the highest and most stable tower possible. It has to be perfectly balanced in order to remain stable and survive. Build as high as you can; watch your tower wobble in the wind; try not to let it overbalance, and cringe if it collapses to the ground! When your tower falls, you lose the game. You can see the tower height and your score at the top of the game screen. Happy building, and mind your head!
Are you suited to becoming a Demolition Expert? Dynamite Blast 2 is a challenging destruction-based puzzle game where you must blow things up by carefully placing sticks of dynamite onto various structures (bridges, towers, buildings) in order to bring them crashing to the ground, below a specified height. Throughout the 35 increasingly-difficult levels, your job is to ensure that your explosives are positioned in such a way as to create MAXIMUM carnage to get you below the target "success" line.
This fun and stimulating skill-based game requires more subtlety than simply pressing the detonator button and hoping for the best. Here, you must utilize smart strategy to decide on weak points in each structure. A basic understanding of physics and the effects of gravity is helpful as you try to ensure that the falling structures are kept as low as possible. Trial and error also comes into play as you attempt to learn from your mistakes! Let’s get to the detonating action!
Play Are You My Blood Type? and learn which blood types match and which don't. The story - Some people have just been rushed to the hospital emergency department from a major car accident. They are rapidly losing blood and urgently need blood transfusions before the operations are completed. It is your job to match their blood types and save their lives. Match the blood type of recipient (bottom of the game screen) with the blood type of one of the donor's (top of the game screen).
The more pairs you match, the more points you get. A total of 10 patients will appear on the screen during each round. Click on a donor you think could be a perfect match for the recipient. The game has a time limit (indicated as a clock on the right side of the game screen), and with each new round you face, the time gets shorter. Your score, round and matches are shown at the bottom of the screen. The slickest part about this online game is to learn which blood types match. The table below will help you. Good luck Doctor, and save as many lives as you can!
Unleash your inner Einstein in an awesome interactive physics-based puzzle game that combines problem-solving skills with wacky scientific experiments! The Successful Experiment is an addicting online brain teaser game where you must use a clever combination of the effects of gravity, eccentric work methods & actions, and a range of scientific tools in order to guide, divert and deflect, an Eight Ball toward a Green Flag so that it makes contact with the flag in each level. This task is made all the more difficult by an array of different environments, obstacles, and challenging physical states of play (some levels are under water, some require floating etc). Using three different types of balls as ‘tools of manipulation’, you must carefully alter the game zone, and push the Eight Ball toward the Flag via bridges, cannons, chutes, water hazards, and more!
This highly innovative and challenging physics problem solving & skill-based activity may prove to be a genuine head-scratcher for even the savviest of puzzle game veterans! Some appreciation for the laws of physics and the effect of gravity on objects is definitely important as you try to logically and methodically influence the game environment in order to create a path for the Eight Ball to come in contact with the Green Flag. Quick reactions are also essential as you have to be smart with your masterful mouse movement in order to get to grips with the raucous experimental chaos that occurs once you set your strategy in motion! Just like most scientific experiments, trial and error plays a big part – so be prepared to be patient in your efforts. Enjoy the great experiment!

Online Huje-Tower Game is an addicting game for kids and teens and ensures hours of fun for the family (the music is catchy too!). The introduction is comical and sets a fun tone - “Somewhere deep underground in sewerage, there live little life-forms – bacteria. One day, they saw the sky and decided to reach the Sky!”
Your aim is to build and balance constructions based on physics, and help the little “Hujos” reach the sky. Start with the first bacteria (which is indicated by an arrow). Then build constructions by dragging/using the little bacteria in your tower construction in order to reach the target line. The sooner you reach the target line, the more points you get. You will see the speed, direction of the wind and the distance to the target line at the right top corner of the screen. Use the left click on your mouse to drag one Huje and join (stick) it to the others in your tower.
New Hujos and objects are introduced at each level. Touch sleeping Hujos with any part of your tower to wake them up. There are many objects to help you reach your goal. “Wheels” attached to Hujos can drive them up to the target if you connect them wisely. Some object are dangerous; Hujos that touch them “die and go to heaven”. Do not forget that the stability of the Hujos tower depends on the wind and is subject to gravitational force.
You can always click on the ‘Restart’ or ‘Back’ buttons if you see that you are not able to finish the level or got stuck with no moves left.

Lever Physics is a challenging, math, physics and equilibrium-based game for upper elementary school / middle school students, high school teens and grownups where you must place and balance weights (fun items and characters) on a ‘seesaw-style’ beam connected to the ground by a pivot (fulcrum). Playing against the clock, you must place any available weights onto the lever (beam), and try to keep it perfectly balanced in the middle.
Some quick physics revision: A lever is a simple mechanical device which consists of a beam or stick or rod, and helps to lift weights with less effort. To be effective (as a lever), it must have a support to pivot on. This pivot is called a fulcrum. Levers can then be used to exert a large force over a small distance at one end of a structure by exerting only a small force over a greater distance at the other end of the same structure (beam). (Physics teachers - Brief correction welcome here if needed..!)
The Law of Equilibrium: A lever is in equilibrium when "the load" and "the effort" balance each other. The effort (weight) multiplied by its distance from the fulcrum = the load (weight) multiplied by its distance from the fulcrum. This law of equilibrium is true for all classes of levers.
For example, 2 pounds of effort exerted 4 feet from the fulcrum will balance 8 pounds located 1 foot on the other side of fulcrum. This effort times (multiplied by) distance about the fulcrum is the "Torque" (rotational force).
Back to Lever Physics Flash game!: Don't be fooled by the fun and playful imagery in this load balancing brain-teaser! It is a tricky, analytical thinking puzzle and logic problem solving challenge that requires good observation skills and hard thinking combined with mathematical and engineering solutions.
This interactive, point-and-click activity allows some trial and error (by quickly placing, removing and re-positioning weights) but you definitely cannot delay your decisions for long as the clock is ticking fast! Ok Balancing Master, can you ‘lever’ yourself to the top of the class?
Paper Floods is a very challenging and quirky physics-based puzzle game for elementary through high school age kids where you have to save a copybook-drawn "Dude" character from a rapidly surging flood in each level. To do this, you must place lifebuoys (life preservers), blocks or rocks in strategic positions so that when the flood comes in, these objects assist your buoyant character in reaching to safety above the new water level close to the top of the game screen.
This tricky, problem-solving brainteaser game causes you to also think outside of the box, and should prove a good exercise for fans of physics and gravity-based puzzles, or anyone who enjoys applying creative engineering and analytical thinking skills to a fun online activity. It could also be used as a fun physics or interactive buoyancy lesson reinforcement activity in the school classroom.
Your strategic decision-making skills really are "central to your success" here as you take potential energy and kinetic energy into account when placing your available objects. There is no time limit on your initial thinking and placement phase, so you have every opportunity to visually predict what is likely to happen, and to carefully plot your new "Dude" buddy's escape from each perilous situation. If your survival items aren’t sufficiently well-placed, it is unfortunately big trouble for Dude! We hope you're ready to use all of your logic skills and determination to save the day!
After a devastating asteroid completely destroyed your space station – your astronaut buddies became lost – scattered throughout outer space! However, the time has finally come to launch a daring rescue mission, and pick up your stranded pals before it’s too late! Rocket Rescue is a challenging physics and gravity-based puzzle game where you must become the hero of the day, and save your astronaut colleagues by launching your rocket toward them (bearing in mind the power of the launch, and the gravitational pull of nearby planets and asteroids in the galaxy). You cannot affect the path of your rocket after lift-off – so make sure your launch calibrations and calculations are as accurate as possible!
This fun and unusual brain teaser requires a basic understanding of physics and gravity – as you have to adjust the angle of your flight path, and take into account how gravity will affect your spacecraft. Utilize your steady hand and problem solving skills to make the precise alterations needed to your spaceship’s course line.

Good luck Captain!
WereBox Game is a fun, addicting, educational brain teaser game where little balls appear to be just ordinary balls, but of course, they are not. At first glance, the game may seem easy, however, level after level, it gets really tricky. This is a great game to play alone at home (or in the office!) with your family or at school as a team/group.
Your aim is to remove all the red objects from the game screen and leave the others by transforming balls into boxes. Note, in some situations that the red boxes cannot be transformed into balls. Use logic to solve all twenty physics-based puzzle levels. You will also need to be very quick in one or another situation as the ball cannot stop rolling once they begin. There are ‘Level select’ and ‘Restart’ buttons at the bottom of the game screen. However, you can only select from the levels you have already passed. Good luck and enjoy the problem solving!
Perfect Balance 3 - Get ready to become completely immersed in this addicting physics-based game, a pressure environment that is all about balance. Perfect Balance challenges your critical thinking skills and requires creativity as well as fast decision making because every second wasted means extra points lost. At times it may look impossible. It is great for non-standard thinking development with no ”out-of-the-box” solution.
Although it initially looks like a simple figure puzzle game created for 5-6 year old kids – it isn’t that simple. This is a game for all ages, and requires a basic understanding of science – gravity, mass, geometry and how balance-beams work. Perfect balance is considered when no object is wobbling or sliding. When an object is unstable – you can see some stardust glowing on the unstable object. Although unstable objects may stand still – they may have fractional motion and this is considered as “almost perfect balance”.
