how to play:
The three blocks that can be placed are displayed at the top, so drag your finger on the circular base and release. At this time, you can pile on the existing block. However, when blocks of the same color touch each other, they disappear.
When you place the block, a red light will appear and measure the height. If you try to place a block at this time, the measurement will be interrupted.
The red light goes out, and when the measurement is completed, the placement status is saved and the height is updated.
If you drop at least one block from the table, the game will be over.
Repeat these steps and stack the blocks just higher.

Note:
After removing the block from the square frame, you can return it.
By moving the light blue bar, you can change the depth at which the blocks are placed.
You can select a block by pressing the square frame.
You can rotate the selected block by turning the circle.
During block installation, measurement cannot be performed until the block is placed or returned.
Even if the game is over, you can start over from where you just saved.

Tips to stack high:
It is hard to collapse if you put it on a foundation like building a house without stacking only one place.
Blocks that have been mistakenly placed can be erased by placing blocks of the same color.
Immediately hitting blocks of the same color on blocks that fall off the table due to loss of balance can be erased and prevented.
