Here are some tips to get higher scores:

1. Start the game by placing blocks in the corners.
2. Always save space for large blocks.
3. Clean off block lines when you can.
4. If you can’t clear a line, get it as close to complete as possible.
5. Keep the board neat. Try to clear at least one line of blocks every turn.
