Wheel calculator
Type in the segments of a wheel: each multiplier and how many segments carry it. The calculator returns the RTP of that wheel, the chance of every prize and how often a spin gives your stake back.
Optional. Pick a casino and a title, and the calculator uses the RTP in our data for it. Only titles with an RTP figure are listed.
The rows below are an example wheel, not the wheel of any game. Replace them with the segments your game shows.
| Multiplier | Segments | Chance | Share of RTP | |
|---|---|---|---|---|
| 50.00% | 0.00% | |||
| 30.00% | 45.00% | |||
| 10.00% | 20.00% | |||
| 10.00% | 32.00% |
How to read a wheel from the game screen
- Count every segmentGo once around the wheel and count the segments for each multiplier. Segments of the same colour usually share one.
- Include the losing segmentsSegments that pay nothing still take up space. Enter them with a multiplier of 0.
- Repeat for each risk levelA risk setting swaps the whole wheel. Each level needs its own list of segments.
How the wheel math works
Every segment is equally likely, so the chance of a multiplier is the number of segments that carry it divided by all segments. The RTP is the sum of each chance times its multiplier.
Worked example
The example wheel has 10 segments. Three of them pay 1.5, so that prize has a chance of 0.3 and adds 0.3 × 1.5 = 0.45 to the RTP. All rows together give an RTP of 97.00%, and 50.00% of spins return the stake or more.
Keno is a paytable game with many more outcomes, and its keno hit odds follow from the same idea. The plinko slot odds are another table of this kind. To turn the RTP of your wheel into money, use the average cost of a session.
What the wheel calculator depends on
- It knows only the segments you type. We have not captured the wheel of any title, and the starting rows are an example.
- It assumes equal segments. A wheel with weighted or hidden segments cannot be read from the screen.
- It gives chances per spin. It cannot say where the next spin stops.
Questions about wheel odds
How do I find the house edge of a wheel game?
Enter all segments with their multipliers. The house edge is 100% minus the RTP shown. The example wheel returns 97.00%.
Does a higher risk level pay better?
Usually the RTP stays about the same and the spread changes. High risk has more empty segments and a few large ones. Type each wheel in and compare.
How often does the top segment hit?
As often as its share of the wheel. On the example wheel the 3.2x segment is 1 of 10, a chance of 10.00%.
Why does my result differ from the RTP in the lobby?
A segment may have been miscounted, the multipliers on screen may be rounded, or the lobby figure may describe another risk level. The calculator shows only what follows from the numbers typed in.
