Nishiki

• Game design by @Marcus [JP] on the Hanafuda Discord
• Quick-and-dirty implementation by @CodaHighland [US]
• You probably don't want to look at the code. If you insist, it is made freely available under CC0 terms.

Objective:

• Remove all of the cards from the table.

How to play:

• You may select any unstacked card that has at least one short edge that does not touch another card.
• You may stack the selected card on another card with the same letter that has at least one edge (long or short) that does not touch another card.
• When four cards are stacked, double-click it to remove it.
• You may not move a card or remove a stack if it would separate the cards into two disconnected groups.
