The game interface consists of multiple layers of stacked blocks with various patterns on them. Players need to put the most corresponding blocks into the card slot below.

The goal of the game is to eliminate all blocks on the interface. The elimination rules are: click to select three blocks with the same pattern and put them into the card slot to eliminate them. If the card slot is full and the block cannot be removed, the game will fail.

But please note that the stacking of blocks is not random. Lower blocks may be obscured by upper blocks. You need to carefully observe and plan the order of elimination.

Sometimes seemingly simple levels are actually full of traps and challenges. Like in some levels, there are subtle differences between seemingly identical patterns. If you accidentally make the wrong choice, the card slot will be filled.

In short, you need to rely on keen observation and clever strategies to successfully pass the levels.
