Ride A Pet fuse calculator
Works from the preview in your Fuse menu. It does not read the game and does not guess hidden rules. You supply the chance, the cost and the time, and it does the arithmetic.
Facts checked . The game updates often, so check your own fusion menu before you spend anything. Unofficial fan site.

Fusions needed for a given chance
| Target chance | Fusions | Coins | Time | Fits limits |
|---|---|---|---|---|
| 50% | 23 | 23B | 11 h 30 min | No |
| 80% | 53 | 53B | 1 d 2 h 30 min | No |
| 90% | 76 | 76B | 1 d 14 h | No |
| 95% | 99 | 99B | 2 d 1 h 30 min | No |
On average a 3.00% chance takes about 33.3 fusions, but that is an average, not a promise: you can get it first time or miss it many times in a row.
Model assumption. Every fusion is treated as independent, with the same chance, cost and time each time. Nobody has verified that the game works this way. Cost does not include the pets you spend.

How to use it
- Open the Fuse menu in Ride A Pet with four pets in the tubes. Do not press Fuse yet.
- Optional: load the same four pets into step 1, with any mutation or trait. You will see what they earn on your ranch, which is what you give up. They are saved with the scenario and go into the share link.
- Copy each possible result and its chance into step 2. Pick its name from the 16 fused pets if the menu shows it, and mark the one you want as the target.
- Copy the cost and the time shown in the menu into step 3.
- Enter what you can spend in step 4: coins, how many times you can supply four pets that give this same preview, and how much machine time you have. The smallest of the three sets the number of fusions.
- Read the chance of at least one target pet, then the table of how many fusions 50, 80, 90 and 95 percent would take.
What the numbers mean
With a chance of p per fusion and n fusions, the chance of at least one hit is 1 − (1 − p)n. The chance of none is (1 − p)n. The calculation is explained, with a table, on the odds page.
What it does not cover
- The value of the pets you put in. Cost here is coins and time only.
- Time you spend collecting pets or waiting between fusions.
- Whether the game really treats every fusion as independent. It is an assumption, not a finding.
- Any link between the Traits or Mutations you deposit and the chances, which no source has measured. The notes you save are a record for you and are never used in a calculation.
