Onefall: One Tap Logic Puzzle

Jawad Ahmed Abbasi

About this game

ONEFALL is a calm, minimalist logic puzzle. One tile falls, hits the next, hits the next — until every tile is gone. Aim the arrows, press ONEFALL, and watch the chain reaction sweep the board like dominoes.

━━━ HOW IT PLAYS ━━━

Every level is a small grid of arrow tiles. One is the red START tile — it's the spark. Tap the other arrows to rotate them, then press ONEFALL. The START tile topples in its own direction. When it hits another standing tile, THAT tile topples in ITS direction. The chain keeps going until it reaches the edge of the board.

Solve the level when the chain clears every tile in a single tap.

Miss, and you lose a heart — but your arrows stay exactly where you aimed them. Three tries per level, no timers, no pressure.

━━━ WHAT MAKES IT DIFFERENT ━━━

▲ ONE TAP TO WIN
No multi-move puzzles. No score chasing. Every level is a single decisive tap that either clears the whole board or it doesn't.

▲ UNLIMITED LEVELS
Every level is procedurally generated and verified solvable. The ramp is smooth — grid size and piece counts grow with your progress. Play as few or as many as you want.

▲ FULLY OFFLINE
No account. No sign-in. No wifi needed. Progress is saved to your device. Play on the commute, on a flight, anywhere.

▲ CALM BY DESIGN
No energy timers. No forced tutorials. Sound and haptics are subtle and can be muted from the settings menu.

▲ DARK MODE
Flip to a print-on-black-paper theme from settings. Same ink, same vermilion, midnight stock.

▲ RISOGRAPH LOOK
Every screen is drawn from a locked palette — paper cream, ink black, and one vermilion accent reserved for the spark, the chain, and the ONEFALL button. Bundled monospace type. It feels printed.

▲ TACTILE FEEDBACK
Rotating an arrow plays a warm marimba tone pitched by the direction it now faces. The cascade climbs a pentatonic scale as each tile falls. A firm haptic thump on the win. Every action gets a response.

━━━ HOW TO PLAY ━━━

Tap the arrow tiles to rotate them (UP → RIGHT → DOWN → LEFT). Aim each one at the next tile it should hit. Press the vermilion ONEFALL button to spark the chain from the START tile. If every tile clears, you solve the level.

━━━ WHO IT'S FOR ━━━

If you like Threes, KAMI 2, Blackbox, Vignettes, or any relaxing logic game that respects your time — Onefall is that kind of game. Play a level in twenty seconds or sink an evening into it.

Made with care. No dark patterns. Just a quiet brain puzzle.
