CHAK! Cascade Merge Puzzle

One tap. Everything snaps to you. Then it chains.

CHAK! is a one-tap cascade merge puzzle played on a 6x6 board. There is exactly one thing to decide: which gem to tap.

HOW TO PLAY
- Tap any gem on the board.
- Every gem of the same tier in its row and column snaps into it and merges up to the next tier.
- The newly merged gem pulls again on its own row and column, so one tap can set off a chain across the whole board.
- Longer chains score more than a single merge.
- Check the NEXT preview before you tap. It shows which tiers are about to appear, but not where.

GEM TIERS
Pebble, Copper, Silver, Gold, Ruby, Diamond, Stardust, Sun. Merge your way from the bottom tier to the top.

WHY IT FEELS GOOD
Most merge puzzles ask for a drag or a swap. CHAK! asks for one tap, and the board does the rest. Reading the grid and finding the tap that starts the biggest chain is the whole game.

FEATURES
- Endless play. There is no stage list, only your own high score.
- One-tap controls. No dragging, no swiping, no timers.
- Plays fully offline. No account, no sign-in.
