Stackra

STACKRA is a falling-block puzzle with two extra systems: SHIFT squeezes your stack, HEAT builds into OVERDRIVE.

The board stays 10×20. Pieces are familiar. Timing is sharp.

PLAY
• Move, rotate, soft drop, hard drop
• HOLD a piece
• Read NEXT, plan the stack
• SHIFT ◀ ▶ to compress the well
• Clear lines to fill HEAT; max heat starts OVERDRIVE

MODES
• MARATHON — climb levels, chase score
• SPRINT — 40 lines, race the clock
• ZEN — slower gravity, quieter juice
• DAILY — one seed for everyone, today

WHY
• Portrait, one-handed
• Haptics and audio can be turned off
• No ads, no account
• Ghost piece, grid, high contrast

Shape the fall.
