3D Suduko Puzzle - Original Japanese Sudoku game with puzzles ranging from easy to very difficult. It is very simple to learn how to play, requires no calculations, and provides a surprisingly wide variety of situations where logic is needed. Children to the elderly can enjoy Sudoku as a pass-time. The game refers to a number placement puzzle also known as "Number Place" in the US.
How to play: Complete the puzzle by making each row, column and 3x3 square contain the numbers 1 to 9. Numbers cannot be repeated in one line. The early Japanese title of this puzzle is "Suuji wa dokushin ni kagiru". But this title is long, then it was abbreviated as "Sudoku". "SU" means number, "DOKU" means single.
Roll up for a tricky, absorbing, head-scratching dice-based puzzle game based on a cunningly straight-forward concept! Endice is an addicting sliding-tile brain teaser challenge where you have to maneuver sets of sliding dice (classic board game-style die) into designated outline zones in each level. Moving the dice around the board is easy – but the catch is that you "must" move each dice a specific number of times (as indicated on the face of each cube), with each dice eventually coming to rest in one of the nominated outline areas. There are no fancy tricks, special moves, or extra bonuses here – just plain, old-fashioned problem solving!
Common sense and analytical-based thinking is the key to success alongside plenty of trial and error. This fun tile-based puzzler becomes increasingly difficult as you progress, and requires a measured ‘step-by-step’ approach. Strategic planning really comes into play, and to ensure success, you need to apply the mindset of a good chess player and think at least two or three moves ahead in advance. Younger players who are ‘cutting their teeth’ in problem solving activities online should enjoy the straight-forward gameplay, while more experienced players should hopefully appreciate the innovative modern twist on a very simple concept. It's time to exercise your brain and play the dice!
Kermix is a cool platform-based, ‘block-sliding’ puzzle game for brain-teaser fans of all ages (from elementary age kids to seniors) where you have to maneuver red blocks into green Exit Blocks in a series of increasingly tricky maze-like levels. You play the role of ‘Block Master’, and must carefully guide the movable crimson blocks through deceptively-difficult grids while collecting gold and bronze coins along the way. The catch is that you cannot move the red blocks individually – your entire fleet moves simultaneously depending on the direction of your command. This poses a fun problem as you attempt to fill all of the different Exit Gateways with individual red blocks whilst ensuring all of the essential coins are collected.
Good observation skills, logic and smart strategy are the keys to success in this head-scratching online problem solving challenge. A good old-fashioned dash of creativity and ‘thinking outside the box’ should also serve you well. While a clock does tick away, there is no pressure on the amount of time you have to complete each level. However, you do have to finish up with as few moves as possible in order to score big. Enjoy, and good luck!
Get ready for an interesting brain teaser puzzle. A real head-scratcher that will test your analytical problem solving skills. It could even have you ‘flipping’ up the wall. Flip 7 is a challenging online puzzle game based on a very simple concept. You are presented with a grid of randomly jumbled red and blue tiles on a grid, and your objective is to ‘flip’ (turn over) all the red tiles over onto blue in 7 moves or less. Remember, the opposite color is on the flip-side of each tile.
At the end of your 7 moves – your goal is to have the grid filled entirely with blue tiles. This is not as easy as it may sound, as you cannot flip individual red tiles - you must flip a row of tiles in each move. You must choose the direction of the row to be flipped, and this determines how many tiles turn from red to blue (or blue to red). You'll need an open mind, the patience to plan a good strategy, and tenacity as this tricky task will really test your heart and desire for logic problem solving. Good luck!
Say “yes” to Nodes - a very challenging and innovative brain teaser puzzle game for older kids, teens, and grown-ups. Your goal in each level is to line up the laser-emitting ‘Nodes’ so that their beams run through every one of the randomly-positioned Blue circles. Drag, and stretch the Nodes all over the game screen in order to create a crisscrossing laser-beam pathway that intersects each one of the Blue circles. The catch is that you only have a set number of Nodes in each level, and that the Blue circles are often in awkward, non-linear locations.
This really tricky and refreshingly original head-scratcher of a puzzle should prove an ideal online activity for those who enjoy exercising their brain power on a good problem solving challenge. Strategic planning ability is vitally important; being able to coldly analyze the grid to see ‘the bigger picture’ is a key skill required here. Trial and error is definitely the path to success as you try out various different intersecting combinations, make minor changes in the angle of your Nodes, and carefully figure out the best way to overlap all of the circles with Red laser beams. Hopefully, you can criss-cross your way through all 20 levels! Enjoy the zigzagging laser beam action!
Sharp logical thinking skills required! Jelly Alien is a "doozy" of a physics-based puzzle game where you have to combine good strategic planning & prediction skills, creative engineering skills and swift mouse movements in order to unite several squidgy, little purple gelatinous aliens into one large body! These friendly extra-terrestrial invaders have become separated by large distances, tricky obstacles, and an unforgiving landscape - and you must don your thinking cap to figure out a way to somehow bring them together in each challenging level. You play the role of the Game Environment Changer, and must use a clever combination of cutting actions, gravity, and the game terrain to create pathways, bridges, and routes for the blobby aliens to join together by cutting wooden objects and ropes. However, it’s not all plain sailing as you have to avoid the dastardly ‘Evil Aliens’ who try to scupper your plans at every turn!
This addicting and surprisingly-tricky online brain teaser activity required plenty of patience and trial and error, and tests your observation skills and ability to figure out a logical solution to each problem. You cannot directly control the movement of the purple aliens, so you have to resort to outside influences – mainly your own cutting tool – in order to move and unite the little guys. In this fun problem solving exercise, your wood and rope-cutting swipes must be tactful as well as accurate! The difficulty of some of the later levels could definitely pose a stern test for some seasoned brain game veterans, while younger gamers should enjoy the immersive interactive action. Happy blob work!
Fire Child – Born Into the Fire is an action puzzle game where you have to find your way along and look for clues in order to help the lovely Lona find her brother who has been kidnapped by bad-guy Sanam. Find an unlocking stone (a lightning circle with a ring) on each level, and stand on it to open the door or gate to the next level. There are guards, wild animals and other obstacles (like simply falling over an edge) that you will have to defeat or avoid along your way as best you can. You may need to look out for objects that you can jump on to, to get around the guards or to reach "bonus life" top-ups.
Perhaps you will initially have to go along the roof to try to get by the guards on the first level. Slash with your staff (weapon) or use your boomerang to fight any obstructors. Note that going too close to a guard will take you back to start the level again, so you must avoid that. Watch out for and pick up Red Heads to regain your lost life-points. Keep an eye on your life (energy) bar. Whenever it runs out, Lona will loose a life. Also pick up face and mask icons to earn extra lives.
Wordoku is a crossword-style letter placement puzzle game for kids and adults of all ages where you have to fill up all of the blank squares in the grid, using the letters A to I. It’s a variation of the classic Japanese game Sudoku but instead of using numbers, you use letters. Although it seems simple, this stimulating and challenging brainteaser requires a huge amount of logical thinking and patience to get the job done right. It’s a fantastic memory and concentration booster and will keep your brain in super-duper, tip-top shape! Have a go; see if you can fill all 3x3 tables.
OK, your goal is to complete the puzzle grid so that every space is filled by one of these 9 letters: A,B,C,D,E,F,G,H and I. There are some rules that you must stick to: Every 9 cell ROW contains only one copy of a letter - Every 9 cell COLUMN contains only one copy of a letter - Every 3x3 BLOCK of cells (divided by the thicker lines in the puzzle grid) contains only one copy of the letter. In short, don’t duplicate a letter in any row, column or 3x3 block – as this invalidates your answer. Once you insert an incorrect (repeated) letter, you can see the row, column or block (illuminated in orange) where the letter might also be. Try and go as fast as you can to get higher rankings. Remember, your score goes from high to low - the longer you take. OK, time for some brainy-brilliance and wonderful word adventures. Have fun puzzle-nerd!
Ready for a fun, rope-cutting physics and skill-based game? Boom Balloon is a tricky, interactive mouse-clicking puzzle game to really get your "spikes" into. Here, you must pop three helium-filled balloons in each level by successfully manipulating the game environment, and carefully freeing and guiding the balloons toward a set of spikes! You play the role of the ‘game-changer’, and have to meticulously plan out a sequence of actions and reactions in each level that results in all three balloons being mercilessly popped (no matter how cute the balloon designs are, they’ve simply got to go if you want to progress).
This challenging gravity-based brain teaser activity can prove to be a tricky test for even the most experienced of gamers. Each level requires careful analysis, logical thinking, good strategy, great patience and determination to figure out the correct course of actions that will result in the balloons’ demise. Once you are ready to set your cunning plan in motion, well-timed swipes of your computer mouse, and fast reaction skills are essential. Beginners beware – later levels feature extremely complex step-by-step solutions that can only be achieved through rigorous trial and error. We hope your enthusiasm for problem-solving doesn't take flight - Remember that only the balloons need to get ‘deflated’ here! Challenging yourself is what it's all about:) Good luck and enjoy!
Alphabet Shoot is a straight-forward yet challenging, physics-based cannon shooting-style game where you have to fire lettered blocks (missiles) at and eliminate designated targets (further lettered blocks) from each level. For example, you have to accurately fire an F missile in order to eliminate a target F block from the game screen. Blast away wooden obstacles, create useful bridges, and clear narrow pathways for your devastating projectiles in a clinical exhibition of cannon shooting at close quarters. Each level takes place in a confined space, so even the slightest misfire can result in disaster!
This online missile-firing activity isn’t all about big guns and explosive action, you also have to carefully and strategically work your way through some tricky problem solving puzzles along the way. Needless to say, accuracy is the key to success here, while later levels also place a premium on quick reactions and good decision making. Ok Sharp Shooter, it’s time to focus your mind, steady your aim, and fire! But can you engineer a solution to each level?
When describing something relatively straight-forward, people often say “it’s not rocket science”. However, that expression certainly doesn’t apply to this challenging, physics-based launching puzzle - which very much "is" Rocket Science! Here, you have to drag, rotate, and launch explosive rocket missiles at awkwardly-positioned planets in a series of tricky levels. Your rockets must be fired from a designated, outlined area, and you have to hit at least one planet with a projectile in order to progress. You might even have to launch simultaneous rockets in different directions, so be prepared for a challenge that is truly ‘out of this world’.
This fun and innovative rocket launching game requires a good deal of logical thinking and precision. Engineering a solution to each level requires the ability to foresee the resultant reaction of your propelled missile, so a good understanding of angles and trajectory is key. You never know too; Maybe one day NASA will come calling at your door! Until then, enjoy this cool problem-solving brain teaser!
Fun Da Vinci is a straight-forward, interactive physics-based puzzle game for both younger and older kids where you have to move and place objects in ideal positions so that cannonballs can be fired and directed into designated urns in each level. Set in the Renaissance period environment of the amazingly gifted Leonardo da Vinci, an innovative inventor, engineer, architect, mathematician, anatomist, painter, sculptor, musician, writer, and so much more.., you play the role of the inventive game changer here. Outlining your solutions to the physics and engineering-based problems on one of Leonardo’s legendary notebooks, you must impress your peers by designing a pathway (route), and strategically positioning various platforms, adjusting bridges, creating pathways, setting up blockades, and more so that the fired cannonballs reach their destination in the urns (fancy vases of the day).
The gameplay and graphics of this atmospheric brain teaser makes it feel like you are being immersed in a Renaissance drawing board. From the cracked parchment-style look of the play area, to the cool background noises mimicking a 15th century Italian city, this is one of the quirkiest puzzles you’re ever likely any time soon. As in all physics-based puzzle games, your observation skills, problem solving and strategic planning abilities, determination, stamina and patience are sternly exercised and tested. Be inspired by the true genius that was Leonardo Da Vinci (1452 – 1519) who even made detailed outlines of helicopter-like flying machines, tanks, and even robots in his spare time – hundreds of years before these machines were actually invented. Happy innovation!
Briker 2 is a really challenging online puzzle game for older kids, teens and grownups where you have to maneuver a ‘rolling brick’ onto and through a golden tile area (plate) on a futuristic 3D grid. Your Brick must “escape” the grid, and you must try to figure out the correct route for your Brick along the grid as quickly as possible. Note that the Brick cannot hang over or go completely off the sides of the grid, or over certain collapsing tiles.
Each grid is carefully constructed so that the Brick only has minimal room to maneuver, and one wrong move sends it tumbling over the edge. Finding the right solution can take plenty of trial and error, so you’ll need to have the patience of a lion! This extremely tricky brain teaser will also help to exercise your creative engineering skills, as you have to try to solve the problem, and find the correct way to position the Brick to get it to the part of the grid that you want.

Color World Origins - Fire as few colored paint balls from your cannon as possible in order to change the color of each box so it matches the color of the character inside it. However, things are not as simple as they seem in this fun brain teaser and challenging color puzzle game. Teleporters, Gravity Wells and Trolley Carts make your job more difficult by blocking your path. Use common sense when you need to move obstacles out of the way, by shooting at them using your cannon.
How To Play: Use your cannon shooting skills to help fill in all of the boxes with the same color as the characters inside them. The fewer shots you fire, the better your score will be! However, keep in mind that it is sometimes better to have more shots wasted, but all characters colored, rather than leaving some of the characters blocked by an obstacle that is impossible to move. Use your computer mouse to aim and shoot the paint balls in the cannon.
Firing the colored balls works in the same way as shooting paintball. If you have ever played paintball outdoors with your friends, you will have a good idea how this game works. Move your mouse around to find the best angle to shoot from, then move it closer to the target to increase the power of the shot. When you are ready, left click on your mouse to shoot the paint at the box. Gain points by accurately shooting and painting the boxes. Use the number keys (1-4) on your computer keyboard or click on the color using your computer mouse to switch color when needed.
Also, use your cannon to fire continuously at any obstacles in your way, and to gain access to various color objects, which you can use to paint the boxes. You will also need to shoot at obstacles to remove them, so that you can release and drop the boxes into containers or areas of the required color. There are lots of different levels to unlock with different color puzzles on each one to figure out, so happy thinking and painting!
If you like complex brain teasers, it’s time that you literally got down to the ‘nuts and bolts’ of online problem solving. Screw the Nut is a challenging physics-based, interactive puzzle game for older kids and teens where you have to strategically divert a hexagonal nut toward a bolt in each level using simple physics and gravity as your aid. Your goal is to unite the two pieces of metal hardware by any means possible – that includes removing objects such as beams and blocks, creating pathways, building bridges, or even using other items to physically push the nut toward the screw in each increasingly intricate level. You play the role of the ‘game changer’, and have to successfully alter the game environment in order to engineer a solution that merges the two pieces together.
This highly-stimulating, skill-based brain teaser requires good tactical and logical thinking skills. You have to carefully plan and figure out a solution using only the objects and tools in front of you. This means that you need think of how items might react to gravity, how you can propel or deflect the nut in certain directions, and how best to decipher what can become an increasingly complex puzzle in later levels. Quick reactions and good timing are also very important here as you have to sensibly choose the correct and tactful moment to make your move. Trial and error definitely plays a part here, and (like all good handymen and women who use these types of tools) you need to be patient and determined in order to succeed. Happy problem solving!
