--

It is a card game played with 52 cards of 4 types each with numbers from 2 to 10, J, Q, K, and A.

At the start of the game, 4 cards are dealt to each participant and the first bet returns.

In the morning, the desired cards are exchanged and the second bet returns.
At lunch, the desired card is exchanged and the third bet returns.
In the evening, the desired cards are exchanged and the last bet returns.

Those who do not die will open the hand, compare the genealogy, and determine the winner.

All four cards are different numbers, and if they have different patterns, they are called maids.
If the number of 4 cards in the maid is A, 2, 3, 4, it is called golf and is the best hand.
Then A, 2, 3, 5 are called the second, and A, 2, 4, 5 are called the third.

And the case where only 3 of the 4 cards have different patterns and numbers is called the base and is a lower hand than the maid.
Finally, if only two of the four cards have different patterns and numbers, it is called two-base and is a lower hand than the base.

If two or more people have the same genealogy, compare the highest number among the cards that make up the genealogy.
The lower player wins, and if all the Game Money Award numbers are the same in the same genealogy, the stake is divided.
