Every figure here is worked out exactly from the wheel’s 54 segments and the hub’s 16 lamps, and checked by adding up all 43,200 equally likely ways a spin can be drawn.
Each number’s segments times what it pays come to the same 40, so no number is a better bet than another: each brings back 9/10 of every medal put on it, the second chance included.
How a spin is drawn
- Three random numbers are drawn the moment SPIN is pressed, always three and in this order.
- The first picks the segment the wheel stops on: one of 54, each as likely as any other.
- The second picks the lamp, for a stop on BONUS: one of 16.
- The third picks where the second chance stops: one of the 50 number segments. A second chance never stops on BONUS.
Each number
| Number | Stops on it | On a second chance | Wins, a spin | Return | Spread (σ) |
|---|---|---|---|---|---|
| ×220 of 54 | 10/2737.04% | 4/1352.96% | 2/540.00% | 9/10 | 1.40 |
| ×410 of 54 | 5/2718.52% | 2/1351.48% | 1/520.00% | 9/10 | 2.18 |
| ×58 of 54 | 4/2714.81% | 8/6751.19% | 4/2516.00% | 9/10 | 2.48 |
| ×85 of 54 | 5/549.26% | 1/1350.74% | 1/1010.00% | 9/10 | 3.21 |
| ×104 of 54 | 2/277.41% | 4/6750.59% | 2/258.00% | 9/10 | 3.62 |
| ×202 of 54 | 1/273.70% | 2/6750.30% | 1/254.00% | 9/10 | 5.19 |
| ×401 of 54 | 1/541.85% | 1/6750.15% | 1/502.00% | 9/10 | 7.40 |
σ: how far what one medal brings back spreads round 0.9 in a spin. ×2 is steady; ×40 swings, and takes far more spins to settle near 90%.
The hub’s lamps (the Milky Way Chance)
| Multiplier | Lamps | Chance |
|---|---|---|
| ×2 | 12 | 3/475.0% |
| ×3 | 3 | 3/1618.8% |
| ×10 | 1 | 1/166.3% |
On average the lamps multiply by 43/16 = 2.6875. A spin stops on BONUS 4 times in 54; with the lamps, that is 43/243 (17.7%) of what every number brings back.
One medal on ×40

| 40 | 1/541.8519% |
| 80 | 1/9000.1111% |

Next to a casino’s big wheel
A casino’s Big Six wheel has 54 segments too. Under the common Las Vegas rules its bets bring back 75.9% to 88.9%, depending on the symbol, and the two single-segment symbols bring back the least.
This wheel brings back exactly 90% on every number instead, as medal machines are commonly set to bring back about 85% to 90%. That is the floor’s own choice, published here.

FLOOR JACKPOT
+ 1% of every medal played goes to the floor jackpot: the site adds 1 medal for every 100 you play, on top of what you play. Nothing is taken out of it, so this machine’s own return is exactly as shown.
Each medal played is also a 1 in 150,000 chance to win the whole pool, which starts again at 1,000 medals once it is won. In the long run it brings back 1.67 medals for every 100 played, but only in the long run: most players never win it.
It is for players who are signed in and have joined the floor, on the first 20,000 medals each plays in a day (Japan time) at the linked machines, with one floor jackpot a day at most.
Like the rankings, the floor jackpot is for fun. The medals played that feed it are what players’ browsers report: the site checks each report against what that machine allows, but it cannot prove it. The draw itself is made on the site’s server, never in a browser.
