Spin a Win
Introduction
Spin a Win is a simple game of luck based on a 24-position wheel with a stopper, like big six. It is by Playtech and can be found in their menu of arcade games.
Rules
The game is played on roulette-like wheel with 24 numbered slots. The numbers are also colored as follows:
- Red: 1 to 7
- Green: 8 to 13
- Blue: 14 to 18
- Yellow: 19 to 22
- Orange: 23 or 24
In the version I played, the bet amounts were 1¢, 2¢, 3¢, 4¢, 5¢, 10¢, and $1.
The following bets are available. Wins are shown on a "for one" basis.

Strategy
Strategy in this game is all about bet selection. I offer the following advice:
- Don't let the game round you down. A safe way to avoid this is to always bet in increments of 10¢.
- Confine yourself to bets that return 97.5%, which is as good as it gets in this game.
