Fortune Mill is an incremental room-unlock game about escaping the mill by pushing five main rooms as far as they will go. This wiki is built around the questions players actually search for: what to buy next, how each room unlocks, how automation works, how New Game+ changes costs, how to get the IdleOn pet, and what every upgrade or item does.

| Darts | The opening room. You throw darts for gold, unlock auto throw, Trial Mode, Shadow Realm, Magician Mousey, and Rattling Gunner. | Upgrades · Secret Shops |
| Lotto | Scratch tickets for money. The room adds five ticket types, Accountant Toad, Abacus Frog, ticket EXP, best-win scaling, and jackpot prizes. | Upgrades · Secret Shops |
