Prize wheel & payout odds
Spin a weighted prize wheel, check the real odds and expected value of every slice, and see how long a reward drip takes to pay out.
The wheel
Value is what the slice pays (in dollars, points or anything else); weight is how many tickets it has. A slice with weight 10 is ten times as likely as one with weight 1.
Each spin is drawn with your device's secure random numbers first, then the wheel turns to land on it.
Odds and expected value
| Slice | Value | Weight | Chance | EV per spin | 1+ in N |
|---|
P(at least one top prize in N spins) = 1 − (1 − p)N, where p is the top prize's chance on one spin.

Reward drip: time to cash out
One free spin every cooldown, each worth the expected value above, until the balance reaches the minimum cashout. Each referral who spins as often adds the referral share of what they earn.
