How to Play De-Block
Quick start
Select the mode from the title, look in the direction of the flowing blocks, and move the central mass using the cross keys. Rotate left and right with A and B, and prioritize small squares to avoid adding too many protrusions. If you miss a piece three times in a row, it's a mistake, so the basic idea is to quickly move it to the side you think it won't reach.
Controls
Cross key: Move the block group in the center up, down, left and right. A: Rotate right. B: Left rotation. START: Game start/pause during play. On the title screen, select GAME A/GAME B with the cross keys.
De-Block — About this game
"De Block" is a puzzle game where you move blocks in the center of the screen and create squares while catching pieces that flow from the top, bottom, left and right. The central mass can not only be moved but also rotated left and right, and the completed rectangle will be erased. If you miss three pieces in a row, it will be a mistake, so securing space is more important than making immediate connections. Game A is a score attack, and Game B is a game where you clear 25 squares in each level to advance.
