Math + Gravity = Fun

Three fun and educational math gravity games. Totally free. No in-app purchases.

In each game the objective is to make horizontal lines of like numbers from blocks the fall down the board. How the blocks stack and combine depends on the particular game and each game focuses on a different mathematical concept.

2^N : Blocks are all powers of two. They combine (add) when they are equal. If they are not equal they stack.

MOD 4 : Blocks of like color combine modulo 4. If they are not of like-color they stack. Metal blocks are inert and dont combine with anything.

+/- : Number blocks, positive blocks & negative blocks fall. Number blocks stack, positive blocks combine and add to any other block. Negative blocks combine and subtract from any other blocks.

Great learning games but they are also just plain fun!
