FAQ
How does the recommendation work?
It ranks upgrades you can afford by payback time — cost divided by the extra Water per click they add over your current pump. The winner is the fastest to pay for itself. If nothing better than your current pump is affordable, it says to save and shows the target.
Why does it sometimes tell me to save instead of buy?
When your current pump is already stronger than everything in your budget, spending on a weaker sidegrade wastes Water. The tool holds your Water for the next real jump and shows exactly how much more you need.
Does it consider pets or rebirth?
Not yet — pets' exact multipliers are unpublished and rebirth economics aren't documented. Pumps are the biggest and best-verified lever, so that's where this tool focuses. More inputs get added as data is verified.
