💡
As speed increases, focus on clearing single rows to keep the grid manageable.

Answers

Frequently Asked Questions

Q What is a 4-line 'Tetris' clear and how do I execute it?

A Tetris occurs when you clear 4 complete rows at once using the long cyan I-bar (straight tetromino). Build a solid 9-column stack with a single 1-column open well on the side, then drop the I-bar down the well.

Q What is the Super Rotation System (SRS)?

SRS is the standardized rotation system in modern Tetris. If a piece would collide with a wall or existing stack during rotation, the engine automatically attempts specific 'wall kicks' to let the piece rotate legally.

Q How does level progression work?

Clearing every 10 lines advances your level, increasing drop speed and multiplying point rewards for future line clears.
