Fill Water Tanks Wiki

The container on your plot that holds water between fills. The official description centers the whole game on it. Level 1 caps at 10 water; the documented upgrades take level 2 at $5 and level 3 at $10 (capacity 100), with later levels scaling into the billions of capacity and costing trillions. Your tank level survives rebirths, which is why it is treated as permanent progression.

The resource you fill and sell. Water is produced while you stand on the fill button, stored up to tank capacity, and converted to cash the moment you step off. Overflow above capacity is wasted. Employees raise how fast water flows; buttons raise how much fits per cycle; Water Gain raises what each unit pays at the sale.

The game's money, paid per unit of water sold. Cash buys every upgrade in the documented shops — tank levels, Water Gain, rolls, buttons, employees — and pays rebirth costs ($50,000 first, scaling to millions, billions, and trillions). Free cash sources include the play-time reward menu and the Friend Boost that grows when friends join your server.

The prestige layer named in the official description ("Rebirth for HUGE Boosts"). Documented behavior: the first rebirth costs $50,000 and pays a permanent 50% boost plus 10 rebirth tokens; money, workers, and cash upgrades reset while tank level, buttons, and pipes carry over. Tokens feed a rebirth tree (percentage boosts, Crystal Vein crystals, auto-rebirth). Button workers unlock at rebirth 3, new shops at rebirths 3 and 5, more at rebirth 8, and prestige at 15 rebirths (2x → 3x at 20 → 4x at 25).
