Tetris
Legendary Soviet-designed puzzle game (1984) in which players rotate + place falling tetromino shapes into complete horizontal lines to clear them — one of the best-selling video games ever with 520+ million copies sold across all versions.
What is Tetris?
Tetris is a puzzle video game designed and programmed by Soviet software engineer Alexey Pajitnov, released initially for the Elektronika 60 computer on June 6, 1984. Named 'Tetris' (τετρ 'four' + πάς 'game'). Players rotate + place falling 7-piece 'tetromino' shapes (I, O, T, S, Z, J, L — each made of 4 blocks) into a 10-wide × 20-tall grid. When a horizontal line is completely filled, it clears + player scores. Game ends when tetrominoes stack to top of grid. Simple but endlessly deep — game speeds up + reflexes need to grow. Cold War IP battle: Andromeda Software (UK) + Bullet-Proof Software (Japan) fought over rights until Nintendo secured console rights (1989 Game Boy launch title) — one of best-selling games ever with 35+ million copies. Total Tetris franchise sales: 520+ million copies (across all versions), making it one of the top 3 best-selling video games ever. Iconic 'Type A' Music (Korobeiniki) recognizable globally. Ongoing competitive scene: Classic Tetris World Championship (CTWC) held annually.

How it works
Objective
Clear horizontal lines by rotating + placing falling tetrominoes. Ultimate goal in Marathon: survive as long as possible + score highest. In Sprint: clear 40 lines fastest. In Tetris 99: last player standing.
Match structure
Each tetromino falls from top of grid. Player: rotate tetromino (4 rotations), move left/right, soft-drop faster, hard-drop instant. Once placed, next tetromino falls. Filled horizontal lines clear + score points. Game speeds up over time (level advances every 10 lines cleared). Game over when pieces stack to top.
Rules
Basic rules
7 tetromino shapes
I (long line), O (square), T (T-shape), S + Z (S-shapes), J + L (L-shapes) — each made of 4 blocks.
Rotate + move each piece
4 rotation states per piece; move left/right + soft-drop (accelerate fall) + hard-drop (instant).
Complete horizontal line
10-wide row completely filled = line clears, blocks above shift down.
Line clears score points
Single: 40 × (level+1). Double: 100 × (level+1). Triple: 300 × (level+1). Tetris (4 lines): 1200 × (level+1).
Level advances every 10 lines
Each level = faster piece drop; classic Tetris starts at level 0, some players reach level 29+ (killscreen).
Game over when pieces reach top
If new tetromino can't spawn, game ends.
Next piece + hold (modern)
Display shows next 5 pieces; hold slot allows swapping current with saved piece.
Advanced rules
Tetris (4-line clear)
Highest-value single move; typically achieved by leaving 1-wide vertical gap for I-piece.
T-spin (modern Tetris only)
Special T-piece rotation into hollow spot = massive bonus points.
Back-to-back combo
Consecutive Tetris or T-spin = +50% score bonus.
Perfect clear
Empty grid after line clear = massive score bonus.
Level 19+ / 29+ (classic)
Pieces move so fast most players can't play; advanced players use 'hypertapping' (rapid button spam) or 'rolling' (rocking motion).
Sprint (40 lines)
Clear 40 lines fastest — top players ~15-20 sec.
Marathon (150 lines)
Clear 150 lines fastest — top players ~2 min.
Tetris 99 battle royale
99 players simultaneously; garbage lines sent to opponents; last standing wins.
Scoring
Points scored per line cleared × level; higher-value clears (Tetris, T-spin) score bonuses.
| Action | Points |
|---|---|
| Single line clear | 40 × (level+1) |
| Double line clear | 100 × (level+1) |
| Triple line clear | 300 × (level+1) |
| Tetris (4 lines simultaneously) | 1200 × (level+1) |
| T-spin (T-piece into hollow) | 800-1600 × (level+1) + back-to-back bonus |
| Perfect clear (all blocks removed) | 800-3600 × (level+1) |
| Soft drop / Hard drop | 1 per row soft, 2 per row hard |
Win condition · Marathon: survive as long as possible. Sprint: clear 40 lines fastest. CTWC: highest score in 6-min game.

Strategies
Save I-pieces for Tetris
4-line clear = highest score; leave 1-wide gap for I-piece.
T-spin setup
Modern Tetris: create hollow that T-piece can rotate into for massive bonus.
Height management
Keep stack flat + low; don't leave holes.
Hard-drop for speed
Instant drop faster than soft-drop; less time per piece.
Hold piece strategically
Save I-piece for Tetris; save O for corner fills.
Perfect clear
Advanced: setup grid to be completely emptied after next placement for massive bonus.
Hypertapping (level 19+)
Classic Tetris: rapid alternating button presses (~15+ per sec) for control at high speed.
Rolling (level 29+)
Modern classic technique: 'rocking' controller into 4 fingers for even faster inputs (~20-30/sec).

Frequently asked
Who invented Tetris?+
