Molecularia is an addicting and educational chemistry-based puzzle game for kids and teens, where you have to connect up all of the available atoms in a maze in order to create stable molecules (making the least amount of moves possible). It’s a tricky and highly enjoyable brain-teaser that takes a bit of practice to get used to. Your goal is to create a molecule by moving and bonding the atoms (tiny, dense, positively-charged nuclei made of protons and neutrons, surrounded (orbited) by clouds of negatively-charged electrons). What? OK, don’t worry about that! You can see the solution in the game screen.

However, you are not shown how to arrive at this solution! Remember, you need to look at where the connecting anchors are on each atom, as connections between two parts are only available one way. There are 14 positively-charged levels to get through! Happy chemistry problem solving!

Interlocked is an online 3D puzzle game with several interlocked figures (blocks), and you have to release one block from the other in 3 D view by thinking about it from different angles. You know those puzzles consisting of a few wooden blocks that are impossible to take apart?  Well, Interlocked is even more addicting fun!  In each level, you are given a unique 3D puzzle consisting of blocks that hold each other together.

Solve the puzzles by separating the blocks and prove that you are real Smart.  Try to fully visualize the problem and to understand the inside structure of each puzzle you face.  Always look for those pieces which hold the rest of the puzzle together and move them.  A slight release of one piece may loosen the other, which in turn may allow you to remove some other piece.  Wrap your mind around Interlocked – the intensive puzzle game!

Cool physics-based puzzle and skill game where you must control multiple characters simultaneously to help a main character to escape the level: Being able to jump powerfully from ledge to ledge is a cornerstone of almost all platform games. However, in the absence of a ‘jumping’ skill, you’d have to be much more canny in your movements, right? Well, let’s put that theory into action! Jumpless is a fun, physics-based platform puzzle game where you have to guide a courageous cube character through the right side of the game screen in each level. The catch is that this cube character can only move from left to right – it cannot jump. Consequently, you need to enlist the help of other cube characters and objects as well as the natural terrain of each level in order to carefully maneuver your little guy to the edge of the game screen – and through to the next challenge.

This innovative online arcade game throws classic gaming conventions overboard, and forces you to think more logically in order to complete each level. You need to display tactful keyboard tapping ability as well as good hand-eye coordination and smart reflexes in order to chaperon your cube to success. Are you ready to take the plunge and relinquish jumping, at least for a short while?

Stalk The Frog is a fun, simple yet addicting and challenging puzzle game with a quirky little character that will drive you nuts! Look at his indifferent expression - those uncaring eyes - that air of superiority. He’s just laughing at you. Ask yourself; can mankind outwit a frog?

Boing boing! He likes to hop around but make sure he doesn’t hop off into the water because then you lose the game. The object of this puzzle game is to stop the frog from entering the water - so try and block him (if you can).

3 Slices 2 combines physics, gravity, and geometry to produce a tricky mouse-clicking puzzle game where you have to eliminate as much or as many of the red and blue shapes from the game area with three strategically-positioned turns (‘slices’) in each level. You are the ‘Master Slicer’, and must figure out the slicing length and angle for each turn that should produce the optimal gravitational reaction of the cut shapes so that a target percentage of the red (or red and blue) shapes are successfully eliminated from the game zone. This is not as easy as you might initially think because you have to contend with awkwardly-positioned shapes, difficult slicing angles, and unorthodox shapes (the blue ones) which rise like helium-filled balloons when freed!

This difficult and addicting online problem solving brain-teaser requires good observation skills, strategic planning and prediction skills, as well as pinpoint mouse-clicking. An appreciation for the laws of physics and gravity is definitely helpful. For example, you may have to perform one or two preliminary slices to move shapes into position before executing one final / main slice to cause the main gravitational reaction. Younger players can effectively ‘slice’ their way into this intriguing, interactive puzzle, while more experienced fans of physics-based challenges should get a good workout with this groovy brain-teaser. Happy slicing!

You will definitely need your thinking cap for this one! Cloudy is a difficult physics and timing-based puzzle game for older kids, teens and grownups where you have to plan out a safe, logical route for a paper plane to cross a dangerous, cloud-filled skyline. Your loyal little paper plane travels along a white-dotted pathway, and your goal is to successfully manipulate that pathway so that your projectile makes it safely from the left hand side of the game screen, all the way over to the right hand side. The catch however is that your paper plane must collect all of the randomly-positioned Gold Stars in order to progress to the next level.

This highly-stimulating and tricky brain teaser activity requires good concentration levels and creative engineering skills, a healthy amount of patience, and plenty trial and error! You have to strategically and meticulously create a simple flight trajectory for your paper aircraft, which is certainly easier said than done with these pesky clouds blocking your way, as well as having to collect all of the Stars, and confined spaces to work with. Your problem-solving skills must come to the fore to figure out a safe and secure flight path through the often treacherous skyline. Have you got the puzzle busting skills to reach Cloud 9?

Use your mouse to construct helpful bridges, tunnels, and pathways to channel the tiny sugar pixels in your desired direction, but beware of awkwardly-positioned obstacles, altering states of gravity, and finicky color-changes. Each cup must be filled with 100 sugar granules, and luckily, you’ve got an unlimited amount of time to engineer a ‘sweet’ solution to each level.

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!

Fit it Quick is a block-fitting, construction-based puzzle game where you must carefully slot (drag and drop) a set of differently-colored, Tetris-style blocks into a specific outline of a structure. As Chief Block Engineer, you must methodically move all of the colored shapes into position so that together they completely fill up the white-outlined area of the structure.

Wake Up The Box 3 is an interesting and challenging physics-based puzzle game for kids and teens where you have to wake up a sleepy little box character by knocking him off a perch in each level. The cute little box-businessman has had a very late's night work, and now he keeps falling asleep in all sorts of wacky places. It’s your job to jolt him awake by prodding and pushing him using pieces of wood, and the force of gravity. You have to add new wooden structures to each level, and hope that they create a chain reaction that will startle the little guy. He’s a stubbornly heavy sleeper, so only a major shock to his system, like falling off a ledge, will wake him from his slumber.

If you feel tired and sleepy yourself – be warned! This is an extremely tricky puzzle that requires a lot of trial and error, thinking "outside the box", and the patience and tenacity of a lion! Your analytical problem solving skills will really come into play here as you have to figure out how to best create a structure that will knock the box-man over. Close concentration and strategy are important too - you must carefully choose the area to place each piece of timber.

The science of gravity must be used to good effect, with each added piece of wood contributing to a structure that might topple him, or create a bridge for another object to disturb his peaceful sleep. This is one brain-teasing activity that won’t have you yawning, and ready for bed. You might just be awake for hours trying to figure out a solution to wake this little box character. Good luck (p.s. shouting at him doesn’t work!) and have fun!

This highly-challenging brain teaser tests your creative engineering skills, strategic planning, good decision making, quick reactions, and more.
