When I am going to perform something in great numbers, I decide a turn.
You may decide a turn by rock- paper-scissors, but do not decide a turn with SmartPhone?
A number assigned at random becomes your turn.
Of course the numerical value that appeared never appears once.
Even bingo is usable. I am all right without a number ball.
[Hit/miss] and [lottery] are on, too.
In addition, you devise how to use, and please use it in every scene.
