Description
Spin the Bottle is a party minigame you unlock in Roxxy's route. It provides different scenes depending on the outcome.
How to play
It is strongly recommended to save before playing. Click on SPIN button to begin a new round. On PC, you can press Ctrl to reset the minigame and avoid landing on the same person again.
Rewards
In the first sessions, the main character kisses the person – Roxxy, Becca or Missy – to whom the bottle points when it stops spinning. After a few games, the reward goes up to a sex scene in the changing room. If the bottle points the main character, then everyone is invited to the fun!
