About
A phone-friendly number-fuse puzzle. Drop the next tile into a column. Matching values fuse into the next power of two. Clear space, chase high tiles, and spend sparks on rescue tools.
What this game is
Fuse Blocks is like a vertical merge puzzle: place tiles, match neighbors of the same value, and watch them fuse upward (2→4→8→16…).
As your board reaches higher tiles, new drop values unlock and older small values slowly retire from the “Next” pool. The pool stays under 10 tile types until you reach around a 1M tile, then soft-caps at 10.
How to play
- Optionally pick a starting floor (2 / 4 / 8 / 16) on a new run.
- Tap or click a column to drop the Next tile into that column.
- Matching adjacent tiles fuse. Chains can cascade.
- Use Hold to park one tile for later if available.
- When the board fills, spend sparks on tools (clear, shuffle, and other powers) or end the run.
