■ Pyramid rules

Playing cards are arranged in the shape of a pyramid.

The rest of the playing cards are placed as a deck at the bottom right of the screen.

The game is clear when all the playing cards in the pyramid have been removed.

Pyramid playing cards can be removed from the bottom row.

Playing cards can be removed by selecting two playing cards totaling 13.
K can be removed alone.

If there is no combination with total number 13, touch the deck at the bottom right and turn it over.
Even if all the decks have been flipped over, you can reuse the unused decks.

Whether or not you can clear this game depends on your luck.

If you do not seem to be able to clear it, there is a new game button, so please try again from the beginning.
