Start Finger Free is NOT A GAME. This is a player picker utility for choosing the start player when playing a board game. Also known as a spinner.
Open the app, place your device on the table, and drag the number of players to you.
The legacy method is available from the wrench icon. Which allows you to tap the screen to generate player placeholders (one for each player). Then tap the "Spin" button.
Start Finger Free has a maximum of four (4) players.
Added to "Kids Games" because every kid I have given this to seems to enjoy it.
