Factris is a game just like Tetris, but you move each of the blocks in the number of factors of that number. For example, if you got the number 8, you would be able to get the block in a 1x8, 2x4, 4x2, or 8x1. Factris is a classic risk/reward high score game. Resize the dropping rectangles according to their factors and pack them together. Factris is challenging (there is no undo) and you need to pay close attention to the size of the rectangles coming next. Improve your numeracy, packing and knowledge of factors with Factris.
The best part is that students get use to factors of numbers, especially for primes.
