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!

Footprints is a very challenging yet relaxing, multi-level, point-and-click puzzle game for older kids and adults where you must navigate (step-by-step) through a series of stepping stone maze-like grids. The catch here is that you can only use each individual tile of the grid once as you find a successful route and pathway to the Green Exit Tile.

This very interesting, problem-solving brain teaser activity for kids, teens and adults requires good analytical thinking skills, smart strategy, and patience to carefully seek and find a solution to each increasingly-complex puzzle. Deep thinkers and board game enthusiasts should enjoy the "route plotting" game play combined with the simple mouse-only controls. Learning from your mistakes (trial and error) play a big part toward solving any tricky puzzle game, and Footprints is no different.

The ambient background soundtrack also adds to the distinctive atmosphere and feel of the game. Are you ready to leave your ‘footprint’ on this challenge?

Line Bounder is a challenging, old school, turn-based strategy game against the computer where your objective is to reach your designated ‘goal area’ by drawing lines across a neon-style grid. The catch is that your PC opponent has its own target to reach, and you must try to outfox him by strategically drawing lines and creating a unique pathway to your goal area. Much like the copy-book game ‘Dots’, you can use existing lines as checkpoints that allow you to continue your line-drawing turn, and make multiple moves in one go!

Skills required: This stimulating and addicting logic and strategy puzzle game requires a blend of smart analytical thinking, strategic planning, creative engineering, determined problem-solving skills, and the ability to make calculated moves that further your position while blocking your opponent's route. Making moves quickly and carelessly will almost certainly result in defeat. Take your time, and try to figure out the optimal move each time it's your turn to draw a line.

Happy shape-shifting!

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?
