It was surprising for me one of my guest don't know this game as I wrote on pastpost  : Couchsurfing experience 8th guest from France

So, I would like to show you the way to share if someone don't know this game because it's really fun! When I was high-school student, my friends and I were always playing this game in almost all of our idle time, for example each break times between class and class, after lunch, or sometimes after the school etc.  Try it with your family  friends if you have cards in your house!

How to play

This game is played by two people and compete " the speed " that which one loses all the cards faster.There are 2 cards on the battlefield which are put by you and enemy, and you and enemy have 4 cards on the table of each side. You can put out the next number the card both " one plus " and "one minus" to the number on battlefield from your 4 cards, then, put out the new card from cards handed and add as one of 4 cards.
Continuing this task and if you lose all cards faster than enemy, you win.

• Separate the cards to Black team and Led team.

• Hold the card with face down on your hand. Put out the 4 cards from the top of cords on your hand in front of you while face up. These 4 pieces are own cards.

• Firstly, put a card on the Battlefield from the top on your hand while face up to start the game but, you and enemy have to say something to make the timing is completely same when you put the card first , like " ready go!" or " 1,2,3", something like that.

• Put the cards QUICKLY if you have next number card against the battlefield one's in your 4 cards (available both "one more" and " one less" ) , then put out a new card to add as a new peace of 4 cards from handed one also very quickly. In this case, “King” is on Battlefield so you can put “ A” because it’s next number from “King”. Also, enemy can put “Queen” at same time. Faster one is prioritized.

• If you put the "A" faster than enemy's "Queen", you add the new card as one of your 4 cards on your side.

• Continuing this competition until you or enemy lost all of own cards in cluding 4 cards.

• When you lost all of cards handed, you can use cards already put on battlefield. leave the top of one of them.
