Foldfuse: Fold & Merge Puzzle

Noctem LLC

About this game

Fold the paper so matching numbers land on each other and fuse. Make the target number before you run out of folds: a calm number puzzle where every fold counts.

A sheet of squared paper lies on your cutting mat. Drag any edge to fold it over. When two equal numbers stack, they fuse into the next number up, and three matching numbers side by side fuse too, sometimes setting off a chain reaction across the sheet. The rules take seconds to learn. The order of your folds is the whole puzzle.

HOW IT PLAYS
• Drag an edge to fold the paper. A live preview shows what will fuse before you let go
• Stack equal numbers to fuse them: 2 on 2 makes 3, 3 on 3 makes 4
• Group three matching numbers to fuse them together and start chain reactions
• Reach the target number within the fold limit
• Solve it in the fewest folds for 3 stars

4 NOTEBOOKS, 60 LEVELS
Each notebook brings a new rule:
• Plain paper: learn to fold, and keep grey stones away from your numbers
• Paper clips: a clipped edge stays down, so fold from another side
• Hole punch: a piece that lands on a hole is lost
• Double sheets: a double-thick piece counts as two
A solver has checked every level, so a solution always exists.
