Swipe a tile onto its neighbor to merge them, then clear every number from the grid without getting stuck. A relaxing math and logic game that is easy to learn and hard to master. HOW TO PLAY 1. Swipe a block left, right, up or down onto a neighboring block to merge them. 2. Same numbers cancel out. Merge two blocks with the same number and both disappear. 3. Different numbers add up. Merge two blocks with different numbers and the swiped block disappears. The block you landed on becomes the sum of the two. 4. Mind the gaps. Blocks can only merge when they are next to each other.
