Hi! This game is very simple. You can immediately understand the rule!
Just place a tiles as the next block layout. It is just like tracing to make them.

Basic Rule
- Look the next block, and place the same shaped block
- Blocks can be placed on the bottom, or adjacent to other blocks
- Also blocks can be rotated and placed 90, 180, and 270 degrees
- When 10 block tiles are lined up horizontally, the line is completed and then the score is added
- Completed tiles will be vanished
- A cross shaped block boosts the score
- If a block cannot be placed in time, it is automatically placed in a random position
- If there is no space to place the next block, the game is over
