Upgrade payback
Upgrade payback
Estimate how long a cash upgrade takes to earn its cost back. Use it for a plot slot or a treadmill level when you can read the price and you know how much extra cash per minute the change should add.
Payback cycles = upgrade cost ÷ extra profit per cycle, rounded up.
Worked example only: 45 extra cash per second is 2,700 cash per minute. Read the real cost on your plot or treadmill sign and the income change on your own labels. This form does not see your plot.
Material planner
Copies needed to fuse
Count how many more matching treasures you still need before a three-item fuse. It does not price the Cash fee, which scales with the items and is shown on the machine.
Required total = materials per upgrade × number of upgrades. Missing = max(required total − materials already owned, 0).
The Fuse Machine takes three similar treasures. Leave copies required at 3 unless the live menu asks for a different count. Owned is how many matching copies you already hold.
Drop probability
Repeated fuse chance
Estimate the chance of seeing one outcome at least once if every fuse is an independent roll. Use it to test a percentage you choose. It does not know the live Fuse Machine table.
Chance of at least one success = 1 − (1 − chance per attempt) raised to the number of attempts.
The default 1 percent is the Alien figure reported in a 28 Sep 2026 fuse write-up. It is not an official drop table. Other mutations were not given percentages. Change the chance before you trust the result.
