It is the "Rock-Paper-Scissors" game that alert and agile nature, flexibility, memory ability are tried. If it is good for a brain tray?!
The rule is very simple! You have four cards and cover on the bet cards from one to the next.
Of course the rival also cover a cards from one to the next. You win if thirty cards are covered earlier. Each stage has different rule. For example, when you lose, you actually win, but you start it not to be confused. When you did a combo, you can confine the movement of the rival.
Please feel fine winning each stage by your good tempo!
