It is a game that arranges cards of numbers next to each other by the same mark in order, before and after 7. People who take out cards one at a time and who lost their hands quickly win. If you can not put out a card, you have to pass, and if you pass three times you will lose at that point. Three people are computers against you. I am "self".
rule
Based on 7, put the same card with the front and rear cards into the battlefield. If it can not be issued, it will automatically become a pass.
Even if there are cards that can be issued, you can pass.
You can pass three times. It will be a loser in the fourth pass.
When 13 is issued, 1 can be issued.
