4-T Puzzle

The fact that Pocket Brainteaser comes as a set of 4 smaller puzzles, makes it feasible for both single and multiplayer play. This game makes for perfect brain exercise and can keep one on their toes. It encourages one to stay focused, and keep trying until they reach the solution, thus building qualities like perseverance. It also indirectly promotes the idea that there are various ways to solve a problem at hand (and thus does not come with a solution manual). This is a perfect game for helping a child bring out both their creative and engineering sides.
