About
Drop glowing glass cubes on an 8x8 grid, fill a line, and watch it burn away in a flash of laser light.
No forced ads. No account.
Just one more piece. One more combo. One more run.
HOW IT PLAYS
• Drag pieces from your tray of three onto the board. Each piece lands right on its glowing outline.
• Fill a whole row or column and it clears with a laser.
• Clear several lines at once for a bigger score.
• Keep clearing lines to grow your combo multiplier. Skip three moves without a clear and it resets.
• Wipe the whole board clean for a big bonus.
• No timer. Think as long as you like. The run ends when none of your pieces fit.
TWO WAYS TO PLAY
• Classic: pure blocks. No power-ups, no second chances. Just you, the grid and your best score.
• Power-ups: the same board with a toolkit, and its own best score.
THE POWER-UPS
• Bomb: drag it onto the board to clear a 3×3 square in one boom.
• Laser: swipe across any row or column to wipe it, full or not.
• Rewire: swap your tray for three new pieces.
• Undo: take back your last move.
• Charge meter: every line you clear charges it. Fill it and you get a random power-up.
• Out of room? One free revive per game clears the middle of the board.
GEMS AND CUBE SKINS
• Gems sit on some blocks. Clear the line to collect them.
• Spend them in the shop on power-ups and cube skins: Wireframe, 8-Bit and Plasma, alongside the classic Glass.
• Gems are earned by playing. They can't be bought.
THE LOOK AND THE SOUND
• Synthwave neon: glass cubes, a sunset grid and glowing neon signs.
• Synth sounds for every drop, clear and combo, with haptics to match.
• Sound and haptics each have their own switch.
EASY ON THE EYES
• Turn on Reduce effects and the clear flash becomes a soft glow. Screen shake, flicker and pulsing stop.
• If Reduce Motion or Dim Flashing Lights is on in iOS, the game starts with Reduce effects on.
FAIR BY DESIGN
• No forced ads: bonus videos play only when you choose to watch one.
• No account, no sign-in. The game sends nothing to us; bonus videos are served by Google AdMob (see the privacy policy).
• Plays fully offline (bonus videos need a connection). Your scores, gems and skins are saved on your iPhone.
• Made for iPhone by an indie developer in Israel.

Bigger bonuses. The gem video at game over now gives at least 8 gems, even after a run with none. In Power-ups, game over also offers a video for a free power-up, and it shows which one you'll get before you watch: always the one you have the fewest of. Every video is still optional.
