Twelve

How to play

1. Drag any row or column to slide it one step. Whatever is on the far end drops off, and a new block may slide in behind.
2. Blocks that touch join into one bigger block, and their numbers add up.
3. A block that reaches 12, 24, 36 or any other multiple of twelve clears.

Drag slowly and the new sums appear before you let go. Pull back if you don't like them.

Color shows what a block still needs. Matching hues make twelve: a pale 5 wants a deep 7.
