GAME MODES

1. SOLO BATTLE
Control both sides simultaneously. Top player uses WASD, bottom uses Arrow keys. Clear lines on your side to shrink your opponent's board. A single-player challenge to master both halves.
2. DUAL TETRIS
Two independent Tetris games side by side. Each player has their own board with no interaction. Perfect for practice or friendly parallel play.
3. BATTLE
The classic head-to-head mode. Two players on one device with territory control: clear lines to expand your board and shrink your opponent's. The player whose board reaches minimum size loses.
4. BATTLE SURVIVAL
Both players share a single large board. White pieces fall from the top, black pieces rise from the bottom. Pieces collide with each other. Push your pieces to the opponent's spawn zone to win.
5. NETWORK BATTLE
Play Battle Survival online against a friend. Create a room and share the 4-letter code, or use Quick Match to find an opponent. Real-time multiplayer via WebSocket.
6. QUICK MATCH
Instant online matchmaking. Enter your name, hit ready, and get paired with another player automatically. No room codes needed.
