How to play “KEISAN-BRIDGE”

< Materials >

You need only one set of playing card !!

< Number of players >

2 – 5 players ( 6 people are possible, but a little ingenuity is required ) per one set of playing card

< Playing time >

About 5 – 10 minutes per one game

< Rules >

1: Distribute 7 cards per one player, and leave the remaining cards in the center of the table as a “deck”.

2: Turn over one card from the deck to determine the “card in the field”, and each player calculates and puts out his/her hand so that it is the value of the “card in the field”.

(“A” means 1, “J” means 11, “Q” means 12, and “K” means 13).

You can use addition, subtraction, multiplication and division.

3: Up to 3 cards can be put out at one turn. You can also put out one or two. For example, if the “card in the field” is “7”, if you have “7” in your hand, you can put it out with one card. If you have “9” and “2” in your hand, you can put out two cards, “9” and “2”, by saying “9 minus 2”. If you have “J”, “4” and “A” in your hand, you can say “J (11) minus 4, and times A (1)” and put out 3 cards of “J”, “4” and “A” (Put your hands in front of you).

4: If the value of the card in the field is not reached no matter how you calculate your hand, take one from the deck and finish. (Even if you can draw one card and calculate, you can’t put out your hand at that time)

5: When all the players put out their hand or draw the card, turn another card from the deck to make a new “card in the field”, and then calculate the hand again so that it will be the new value.

6: The player who runs out of hands first wins. (For the loser, the calculated value of the remaining hand is the “penalty point”. For example, if “3”, “8”, and “K” remain, the penalty point of that player is 3 + 8 + K (13). ) = 24.) Penalty points will be 0 for those who go up.

7: Repeat this game 5 times (this is called “one set”), and the player with the least total penalty points wins (you can decide the victory or defeat in one game).

There are a few more detailed rules, but this is the only basic rule.

It may seem difficult to write in sentences, but once you play the game, even kindergarten students can understand the rules (when teaching kindergarten children, it is better to play the game using only addition and subtraction). And even grandpas and grandmas can enjoy this game. This means that kindergarten students and grandpas and grandmas can play the same game together. I think it’s a game that people aged 5 to 105 can play with !!
