About the game
In DNA Blocks you drag pieces onto an 8×8 board and fill rows or columns to clear them. The twist: every block carries one of four genes – A, T, G or C – and clearing a line with enough genes of one kind triggers a mutation.
Mutations are the heart of the game: A blasts a bonus line, T turns the next piece into a ★ wildcard and grants a rotate token, G adds 50% to your points for three moves, and C drops a 2×2 bonus crystal. Clears on consecutive moves multiply your score, and a completely clean board pays a bonus.

How to play DNA Blocks
- Drag one of the three tray pieces onto the board. There is no free rotation – unless you hold a 🔄 token from a T mutation.
- Fill a whole row or column to clear it. Several lines at once, on consecutive moves, multiply your score.
- Watch the genes on the blocks: a line with enough matching genes triggers their mutation.
- The game ends when no tray piece fits the board. In zen mode you get a rescue instead.
