Roulette with several balls

I am now thinking to make a smartphone application which is a roulette, but dislike the others, it has several balls...

the situation that would be used is now thought in a party or some drinking place...

i don't know it is only japanese or international thing... doing some game at drinking places...

decide how many of the people drink, then set the number of ball according to that, and start the roulette....

then the guys pointed by the roulette would drink!

haha, simple game, but if something like that is on a table, i will start using it

actually now what im thinking of is something different from normal roulette, but thinking of having a needle (? or something sharp to point out) and the roulette table is divided into the areas which is defined by the number of the people, then the needle will turn around to point out the area

Thank you for reading :)
