Extended data

At the beginning of the game, the first card on the top of the library is opened as the guide card, and the dealer plays cards according to the guide card, and then the cards played by the player become the guide cards in turn, that is, the last card played is the guide card. When there are no cards to play, draw 1 card from the top of the pile. If you can play this card, play it immediately, if you can't, skip it.

When a card can be fined because it has no cards, if there are no cards to play after drawing, continue to draw cards until there are cards to play. When you have a card exactly the same as the guide card (color and number), you can play this card immediately, regardless of the order of playing. This rule is limited to digital cards.
