Fuseline

Fuseline is a grid puzzle built around three elements that chain in completely different ways. Fire spreads to every touching cell, including diagonals. Spark only chains along diagonal neighbors. Water spreads only orthogonally. Tap a cell to trigger its chain reaction - and when a fire chain reaches water, it flashes into steam, clearing the water too for a bonus, while stopping the fire's spread.

Learning how each element behaves, and setting up multi-element chains on purpose, is the whole game. Forty handcrafted levels grow the board from a tight 5x5 grid up to a demanding 9x9, with your move budget scaling to match.

Key features:
- Three elements with distinct chain rules: omnidirectional fire, diagonal spark, orthogonal water
- Fire-meets-water steam conversions for bonus clears
- 40 handcrafted levels plus a Daily Challenge with a fresh 7x7 board every day
- Three difficulty settings that adjust your moving budget
- 12 achievements, including precision-clear and diagonal-chain challenges
- A local top-10 leaderboard tracking both level clears and Daily Challenge scores
