Challenge the limits of your memory.
Match the patterns on the randomly shuffled cards within the time limit.
If you match two pairs of cards, the pair will disappear.
Try to erase all the cards within the time limit.
Cards dealt are randomly lined up on the field and may overlap.
In such cases, you can rearrange the cards by acquiring shuffle items that appear from time to time.
There are also items that extend the time limit or increase the number of mistakes.
