Block Stack
Drop neon tetrominoes into a retro arcade cabinet and clear complete rows before the stack hits the ceiling. Block Stack blends classic line-clearing puzzle action with a glowing 8-bit aesthetic — free to play in your browser, no download required.
Game Objective
Stack falling blocks to fill complete horizontal rows. Each cleared row earns points and removes that line from the playfield. Speed increases as you level up. The run ends when a new piece cannot enter the board — aim for the highest score on the arcade leaderboard.
How to Play
- • Arrow keys move the active piece left and right
- • Up arrow rotates the piece; down arrow soft-drops for bonus points
- • Space bar hard-drops the piece instantly to the ghost outline
- • Fill an entire row to clear it and advance toward the next level
- • Clear multiple rows at once for a bigger score multiplier
- • Press P to pause mid-game
Tips and Strategies
- • Use the ghost outline to plan where each piece will land
- • Keep the stack flat — tall spikes limit your placement options
- • Save the long bar piece for clearing four rows at once
- • Soft-drop for control; hard-drop only when you are sure of placement
- • Watch the NEXT panel to plan two moves ahead
