🧱 Block Stack

Rotate and move falling blocks like in Tetris to fill horizontal lines and clear them. Use hold to stash a block, check the next 5 pieces, and go for T-spins and combos.

• Keyboard← → to move, ↓ to soft drop, Space to hard drop
• Rotate↑ or X rotates clockwise, Z or Ctrl counterclockwise
• HoldC or Shift. Stores one block for later use (once per drop)
• MobileDrag left or right to move, tap to rotate, swipe down to hard drop, swipe up to hold
• ModesMarathon 150 lines, 40-line Sprint, and 2-minute Ultra each have their own leaderboards. Battle mode pits you against the computer at 4 skill levels.
• ScoreScore more by clearing multiple lines at once, T-spins, combos with consecutive clears, back-to-back (B2B) chaining of hard techniques, and all clears that empty the board
