A dopamine-engineered habit system reverse-engineered from slot machine psychology.
Slot machines are called the "crack cocaine of gambling" because of intermittent reinforcement โ unpredictable rewards spike dopamine far more powerfully than guaranteed ones. A "maybe" is neurologically more addictive than a certainty. This system applies that same psychology to the habits you actually want.
Before spinning, you can cash in matching clips to upgrade the tiers available on the wheel:
| Cash In | Unlocks |
|---|---|
| Nothing | Tier 1 + Jackpot + Bonus |
| 2 matching clips | + Tier 2 |
| 3 matching / 1 โจ Gold | + Tier 3 (all unlocked) |
Unused clips stay in your hand for future spins.
| Segment | Chance | Reward |
|---|---|---|
| Tier 1 | 40% | โ |
| Tier 2 | 30% | โ |
| Tier 3 | 20% | โ |
| ๐ฐ Jackpot | 2% | โ |
| โญ Bonus | 8% | Bonus wheel + best tier |
Near miss: Landing on a tier you haven't activated gives Tier 1 โ just like a slot machine!
