Tetris

How to play

Tetris is the iconic falling-block puzzle: seven tetrominoes (I, O, T, S, Z, J, L) cascade down a 10-wide, 20-tall playfield, and you slide, rotate, and drop them to pack complete horizontal rows. Each full row clears and pushes the rest down; clear four at once and you score a Tetris. Wuti Zone's Tetris ships SRS-correct rotations with wall kicks, a 7-bag randomizer, a 5-piece preview queue, hold piece, hard drop, and a deterministic daily seed (every player worldwide gets the same bag sequence on the same UTC day). Survive as long as you can — the gravity speeds up every 10 lines cleared.

Rules

• Playfield: 10 columns × 20 visible rows. Pieces spawn at the top center and fall under gravity.
• Seven tetrominoes (I, O, T, S, Z, J, L) appear in a 7-bag shuffle — you see every piece exactly once per bag, then the bag reshuffles.
• Clear a row by completely filling it; clearing 1 / 2 / 3 / 4 rows in a single lock awards 40 / 100 / 300 / 1200 points (× level + 1).
• Clearing a Tetris (4 rows) is the highest-value clear; consecutive clears chain a combo bonus of 50 × combo × (level + 1).
• Hold one piece in reserve at any time (one swap per piece lock). Useful for parking an early I-piece while you build a Tetris well.
• Soft drop (↓) descends one row at a time for +1 point per cell; hard drop (Space) slams down to the floor for +2 points per cell.
• Every 10 lines cleared the level rises by 1; gravity halves per level via the standard 1000 × 0.85^level formula, floor 50ms.
• Game over when a freshly spawned piece overlaps an existing block at the top of the field (block-out).
• Daily mode: every player worldwide gets the same 7-bag sequence for the same UTC day. Refresh your tab and the in-progress game resumes.

Strategy tips

• Keep the stack low and flat — build a clean surface and avoid holes you can't reach with a future piece.
• Save one well column (usually the rightmost) for the I-piece, then drop the I vertically to clear four rows at once for the Tetris bonus.
• Don't soft-drop reflexively. Hard drop is faster, awards more points, and avoids the lock-delay surprises.
• Use Hold to park an awkward S/Z/L early when you have nowhere good to place it; pull it back when the well calls for it.
• T-spin setups are advanced — leave them until you can read the field in three pieces; for casual marathon a flat stack beats fancy tricks.

FAQ

Is Tetris free?

Yes. Wuti Zone's Tetris is completely free, no signup, no download.

How does daily mode work?

Daily mode picks a deterministic 7-bag sequence based on the UTC calendar day. Every player worldwide sees the same pieces in the same order that day — refresh your tab and you'll resume the same game.

Does my best score save?

Yes. Your best marathon score is stored in your browser's localStorage. Daily completions also bump your streak.

Can I play on mobile?

Yes. Tap to rotate, swipe left/right to move, swipe down for soft drop, swipe down fast for hard drop, two-finger tap to hold. Cells stay big enough for thumbs.
