Quadrillion is the ultimate solitaire game - multi-level, single player, brain teasing fun.
Start a new challenge in a snap, just place the four magnetic grids together and start playing. Can you fit the 12 puzzle pieces on the game board you just created without placing any puzzle pieces on top of the black or white dots? Flip, turn, place, arrange, rearrange and connect them all until the puzzle's solved. Follow the 60 challenges in the booklet or simply snap the boards together and create your own - every challenge has multiple solutions but can you find one? Perfect for the budding IQ genius.
Eight year olds like more challenging construction sets, and are starting to get seriously interested in science. Anything involving potential explosions or high speed makes a good present. They can also start doing cleverer magic and love doing tricks. And anything they can throw or shoot at someone else is also very popular.
