## What is DE?

DE-BLOCKS reinvents the puzzle game with a unique mechanic: pieces are fired upward from a cannon while a wall descends from above. Clear lines before you get crushed!

  REVERSE GRAVITY
  Forget everything you know about Tetris. Here, pieces float upward and stick to the ceiling. Move your cannon, rotate your pieces and aim carefully to build perfect lines.

  30 ARCADE LEVELS
  Progress through 30 increasingly challenging levels:
  • Levels 1-10: Master the basics as the wall speeds up
  • Levels 11-19: Dodge mobile obstacles that deflect your pieces
  • Levels 20-30: Race against the clock — clear lines before time runs out

  MARATHON MODE
  Survive as long as you can against an ever-accelerating wall. Beat your records and climb the Game Center leaderboard!

  GAME MECHANICS
  • 7 classic pieces with tap-to-rotate controls
  • Combos: clear 2+ lines at once and the wall rises back up!
  • Joker: undo your last placement if you make a mistake
  • Adjustment phase: slide a landed piece for 3 seconds

  NEON ARCADE STYLE
  Dive into a retro atmosphere with neon visuals, 3 original tracks and immersive sound effects.

  Available in English, French, Spanish, Italian and German.
