Doubt (playing card game)

▼ Rule outline
The four players in turn play cards from A (1) to K (13).
If you have all the cards you have, you win.

▼ Rule details
・When you take out the card, put it on the back side.
・If you don't have a card to play, you must lie and give out another card.
・On the other hand, if the opponent is playing a card and you think that card is a lie, you will doubt and call "Doubt".
・If the doubt hits, you can let the opponent take all the cards that are in play, and if the doubt loses, you will take all the cards that are in play.
・Once you have taken out the cards up to K(13), you can start from A(1).
