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!

Prepare to ascend to the heights of physics puzzle-busting success as you take on a fun ‘Wild West-themed’ problem solving brain-teaser (mainly for middle to high school age students). Amigo Pancho 3: Sheriff Sancho is a highly enjoyable and stimulating gravity-based game where you must quickly and carefully alter the environment in order to safely guide an eccentric officer of the law out of a deep ravine (canyon)! Sancho needs to ascend through each level by clutching onto rising helium-filled balloons, and your job is to clear a path for Sancho to the top of the game screen using a combination of good strategic planning and swift mouse clicking. The catch is that there are numerous dangerous obstacles and hindrances in poor Sancho’s way - including missile-firing snakes, jagged cliff edges, narrow passageways, and more.

Bubble Quod 2 is a cool, teamwork-based platform puzzle game where you have utilize levels, push objects and create chain reactions in a physics-based setting to help two brothers encased in bubbles to escape from a dangerous, acid-filled facility! Sam and William were working hard at a rubber duck factory when a huge explosion sent everything into disarray! Now, with chaos raging, and acid leaking everywhere, you must become a hero and help guide the little siblings out of danger through good-old problem solving know-how, smart platform game reactions, fast keyboard skills, and a great amount of teamwork (In some levels, one of the brothers might have to help to release the other from a deep pit, or propel them onto higher ledges etc). The catch is that Sam and William are both trapped inside large latex bubbles which makes their movement relatively difficult to control.

This epic 25-level, interactive solution-finding arcade adventure combines the physical aspects of classic platform games with the mental challenges of ‘boxed-in’ brain teasers such as Cut the Rope. This means that, as well as being fast, accurate, and tactful in your keyboard tapping, you also need to display good strategic planning and level management skills as you attempt to figure out how to escape each scenario. Remember: Never underestimate the power of teamwork!

This challenging brainteaser game and fun team management activity is a good test of your ability to combine the characteristics of two different characters to your advantage.

Protect the vulnerable! Shield a poor old defenselessness cow from invading alien missile-fire in this interactive puzzler by carefully dropping large blocks within the game zone! Protect The Cow: Level Pack is a top physics-based game and problem solving puzzle for older kids and teens where you must methodically drop blocks into the game environment in order to create a protective shield for a happy-go-lucky cow inhabiting land that is suddenly under attack from a naughty missile-firing alien! As soon as you make your final block-dropping effort, the alien spaceship swoops onto the screen, and fires a deluge of cannonball missiles over the area around this innocent farmyard animal.

This quirky and challenging brain teaser requires very good observation of the terrain, savvy creative engineering skills, and a highly determined problem solving attitude. You need to quickly figure out the ‘lay of the land’, and then systematically add defensive barriers that provide durable cover for your cow (For example, this might include building makeshift bridges, closing off pathways, and even propelling the cow to other areas using the powerful, descending blocks). Your alien opponent can prove quite adept at exposing the weak points in your makeshift defensive structures, so lots of trial and error, and patience play an important role in your attempts to protect your cow. Are you ready to create and construct makeshift fixes to solve each puzzle level?

An interactive sliding puzzle game that requires focus, quick thinking, creative design skills, strategy, and lots of determination under pressure. Create a viable electricity pipe channel (connection) between the two electric glowing sources, against the clock! Connection is a challenging online visual puzzle game where you must methodically re-arrange (slide) jumbled tiles on a large grid in order to create a continuous pipeline where electricity flows freely from the start to the end point. Your initial problem is that the various corner pieces and straight pipe tiles are positioned randomly around the huge game grid, making pipe construction tricky and time-consuming! And then, to keep the clock running, you must continue to generate electricity via creating further successful connections!

This addicting maze-like, brain-teaser game provides a good fun exercise and test of your concentration levels, observation skills, quick reactions, and love of problem solving as you attempt to pinpoint the various tiles (square pieces) needed to complete your pipeline, and then slide them into position as quickly as you can. Swapping tiles randomly around at speed is of no use if you don’t have a coherent, logical plan to join up the electricity line. The overall ability to step back momentarily, to review and see the bigger picture, and then react urgently is essential here as it is in many real life situations everyday. Now, are you ready to take on this electrifying task?
