Simple Roulette Maker
Read full descriptionHide full description
This app allows you to create a roulette wheel, which is useful for deciding things randomly. You can set the number of items on the roulette and the likelihood of each item being selected (the size of the item) to create your own original roulette. The data of the created roulette can be saved, so you can quickly prepare a roulette for various situations. When you press the button in the center of the roulette, it spins either clockwise or counterclockwise. The spinning speed is random, and the roulette can be stopped by either the passage of time or by tapping the center button again. Please use it like drawing straws when you have trouble deciding something!
