Go to Spin to Win → Rewards and click Add New. You can choose from:
- Percentage discounts (e.g., 10% off)
- Fixed discounts (e.g., $5 off)
- Free shipping
- Free product giveaways
- Coupon codes (predefined or auto-generated)
- Try again / no prize
- Custom messages (e.g., “Try again tomorrow!”)
Each reward lets you set probabilities, so you control how often it appears.
In the left part of the screen you have a total probability percentage. Ideally, stick to 100%.
