A win ratio is the percentage probability of the wheel landing on a specific slice during a spin. Win ratios give you full control over how often each prize is awarded.

How they work

Each slice on your spinner has its own win ratio. All slices together must add up to exactly 100%. When a spin fires, Swivel uses these ratios to determine where the wheel lands — a slice with a higher ratio will be landed on more frequently than one with a lower ratio.

Here's an example distribution for a 5-slice spinner:

Prize Win Ratio Approximate frequency
$25 Gift Card 30% ~3 in 10 spins
Extra PTO Day 15% ~3 in 20 spins
Coffee with CEO 20% ~1 in 5 spins
Team Lunch 25% ~1 in 4 spins
$100 Grand Prize 10% ~1 in 10 spins

As a quick reference: a 5% ratio means the wheel lands on that slice roughly 1 in 20 spins; a 40% ratio means roughly 2 in 5 spins.

Important

All win ratios across your slices must add up to exactly 100%. Swivel will prevent you from activating a spinner where the total doesn't equal 100%.

Setting to 0%

You can set a slice's win ratio to 0%. A 0% slice will still appear visually on the wheel when it spins — but it can never be landed on. This is useful for prizes you haven't stocked yet but want to display as coming soon, or prizes you've temporarily suspended.

Tip

Use 0% slices to tease upcoming prizes. Your team will see the prize on the wheel but know it hasn't been unlocked yet — a great way to build anticipation.

Tips

  • Low ratios for big prizes. Reserve 1–5% for high-value prizes like a $100 gift card or an extra day off. This keeps them exciting and rare.
  • Higher ratios for everyday prizes. Set 20–40% ratios on smaller rewards (branded swag, $5 coffee) so winners feel the love regularly.
  • Each spin is independent. Past results don't affect future spins. Landing on a $100 prize this spin doesn't make it less likely next time — each spin is calculated fresh.
  • Edit anytime. You can adjust win ratios on an active spinner at any time. Changes take effect immediately on the next spin.
