Player guide
Falling blocks strategy
The safest Tetris strategy is simple: keep the stack low, leave a clean well for long pieces, and avoid creating holes that cannot be filled from above.
- Keep one side open for long pieces if the build supports four-line clears.
- Flatten the middle first because tall center stacks reduce movement options.
- Place awkward pieces where they repair the board instead of chasing a perfect clear.
