Bit Crush: Merge Block Puzzle

Most block games merge the moment you place a piece.
BitCrush merges when the beat hits.

Drag blocks onto a 7×7 grid. When matching groups form, they glow with a dashed border - pending merge. A geometric Sweeper crosses the board in sync with the BPM. When it hits a marked group: the number doubles. If more groups form from the cascade, they merge too. The chain continues until nothing is left to combine.

Each merge is a note. Each chain reaction is a chord. Each skin is a different song.

- DAILY CHALLENGE -

Come back tomorrow.

- FIVE SKINS. FIVE SOUNDTRACKS. -

Each skin has a unique Sweeper geometry, a different BPM, and an original algorithmic soundtrack synthesized in real time from pure code - zero audio files on disk.

MONO: 80 BPM · Line sweep · Flatline · A minor pentatonic
PHOSPHOR: 95 BPM · Diamond wave · Reactor · G major
AMBER: 110 BPM · Sine sweep · Driftwood · Bb major
INVERT: 125 BPM · CW Spiral · Blackout · F# minor
CORRUPT: 140 BPM · Cross pattern · Meltdown · B diminished

Unlock each skin by reaching a score threshold. No purchase required.

- HOW TO PLAY -

Drag a block from the dock onto the grid before the penalty timer runs out. Matching groups that form become "pending merge" - outlined with a dashed border. Wait for the Sweeper. When it crosses them: merge. Build chains. Time them with the beat. Score big.

The Shuffle power-up (earned every 2,000 points) redistributes every value on the grid - the panic button you will learn to love.

- DESIGN -

Strict 1-bit rendering: exactly two colors per skin. Zero gradients. Zero greys. Dithering patterns encode each block value - from a single pixel for value 1 to solid fill for the maximum value 64.

- NO PAY-TO-WIN, EVER -

No energy system. No loot boxes. No gacha. No timers that drain while you sleep.

Free to play with optional ads. One purchase removes interstitial ads forever. A second purchase unlocks all skins immediately. That is the complete monetization model.

Playable offline. No account. No login required.
