About Stackline

A bright, fast block-puzzle sprint. Find the gaps, plan with the landing preview and chain satisfying line clears. You have 120 seconds and up to 150 pieces to make every placement count. Fresh pieces every run, daily worldwide leaderboard.

How to play

Pieces fall into a 10×20 well. Move, rotate and drop them to complete horizontal lines — a full line clears.

Desktop: ← → move · ↑ or X rotate clockwise · Z rotate counter-clockwise · A rotate 180° · C or Shift hold · Space hard drop · ↓ soft drop.

Touch: drag left or right to move (push to the edge to hit the wall) · tap the left / right half to rotate · flick down to hard drop · drag down to soft drop · swipe up to hold.

Use the HOLD, ROTATE and DROP buttons for precise touch control. The landing preview highlights lines your next drop will clear; a shrinking bar shows when a grounded piece will lock.

Hold swaps one piece per lock. The next five pieces and a stack-height warning help you plan ahead. Returning from another tab leaves the game paused until you resume. Pause time is free for 60 seconds per round; extra time runs the game clock.

The round ends at 120 seconds, after 150 pieces, or when the stack tops out — whichever comes first. Your score at that moment is your record.

Scoring

Single 100 · Double 300 · Triple 500 · Quad 800 — all multiplied by level. Level rises every 10 lines and caps at 8.

T-Spin 400 / 800 / 1200 / 1600 · T-Spin Mini 100 / 200 / 400. Back-to-back difficult clears ×1.5.

Combo 50 × chain × level. Perfect clear 800 – 2000 (back-to-back Quad perfect clear 3200) × level.

Soft drop 1 per cell, hard drop 2 per cell — drop points are capped at 5% of your total.

Every run gets a fresh piece order from the server seed, so memorised sequences count for nothing.

Your next climb starts here

When does the next round begin?

A fresh shot at the leaderboard starts —, your local time. The whole world starts the next round together.

What happens at the reset?

Today's board becomes final and a fresh, empty board opens. A run started less than six minutes before the reset may finish after the board has closed — that run can't be registered.

How are ties ranked?

Equal scores: the newer entry ranks higher, so a tie with 20th place still gets you on the board.

Can one player hold several places?

One player, one personal best per game, each round. Beat your score to climb higher. Your record follows this browser; clearing site data or switching devices gives you a fresh start.

What happens when a game gets an update?

If scoring changes, a fresh leaderboard keeps the competition fair. Everyone on that board plays by the same rules.
