About Chain Fuse

Chain Fuse is a puzzle game on Playket: link equal numbers, climb by doubles and fuse the whole chain into one big tile. It is free to play instantly in your browser — no download and no sign-up — on phone, tablet and desktop.

How to play

Drag through touching tiles in any of the 8 directions, diagonals too. A chain starts on two equal numbers, and each next tile must be the same number or double the last one. Drag back to unlink; let go to fuse the chain into one tile (its sum, rounded up to a power of two) where you stopped. Longer chains and bigger tiles score more. The run ends when no two equal tiles touch. Keyboard: arrows or WASD move, Q/E/Z/C move diagonally, Space links (press it again on the last tile to fuse), Backspace unlinks, U undoes. Earn extra undos by making new best tiles from 256 up.

Tips

  • Long chains of small tiles snowball: five 2s fuse straight into a 16.
  • Climb as you go, like 4 → 4 → 8 → 16, to make big tiles without needing many of them.
  • End a chain next to a matching big tile so the result is ready for its next fuse.
