Stack Attack: Block Puzzle

Build it. Break it. Beat it.

Fit colourful shapes onto a 9 by 9 board, complete rows and columns, and make room for your next move. Build combos, earn power-ups and find your favourite way to stack.

Five ways to play

Classic: chase your personal best without a countdown. Plan your drops and keep the board open.

Time Rush: see how much you can clear in 60 seconds.

Beat CPU: race a computer opponent across three difficulty levels. Reach 300 points first or outlast the grid bot.

Daily Drop: tackle a fresh shared daily challenge. Clear 10 lines within 20 moves.

Stack Trials: work through 60 fixed-piece puzzles across six chapters. Use the pieces given to leave the board empty. Earn stars, revisit earlier trials and use hints or Undo when you need another approach.

Make every drop count

Clear lines to charge your Stack Ups. Tower Sweep clears a row. Stack Bomb opens up a 3 by 3 area. Use Hold to save a shape for later and Undo to rethink a move where available. Stack Trials uses its own fixed-piece rules, without power-ups or Hold.

Play your way

Drag blocks into place, or select a shape and tap the board. Enjoy colourful arcade visuals, music for each mode and punchy sound effects. Adjust music, sound, vibration and reduced motion in Settings.

Core gameplay works offline, with personal bests, trial stars and settings saved on your device. No account is required. Saved records are local; this is not cloud synchronisation or an online leaderboard.

Ads are your choice

There are no banner ads or forced interstitial ads. In Classic and Time Rush, an optional rewarded ad can grant one extra Stack Up or one continue, each limited to once per run. Beat CPU, Daily Drop and Stack Trials have no rewarded-ad advantages. Core play remains available without watching ads. Rewarded ads require an internet connection and may be unavailable.
