For the Roblox game Steal An Egg. Type your Oni Tiger's weight and mutations to see what it earns and how long it takes to afford your next upgrade.
Updated · game data from the wiki as of 30 September 2026 · changelog
Short answer: a Oni Tiger earns $600M per second at its base weight of 300 kg with no mutations. That is $2.16T per hour. Every doubling of its weight multiplies income by about 1.53, so a Golden Oni Tiger at twice the base weight (600 kg) earns $2.3B/s. Type your own Oni Tiger's weight and mutations below.

Oni Tiger income by weight
No mutations, no boosts. The size multiplier is (weight ÷ 300 kg)37/60 up to 125× base weight, then grows more slowly.
| × base | Weight | Size | Per second | Per hour |
|---|---|---|---|---|
| 1× | 300 kg | ×1.00 | $600M | $2.16T |
| 2× | 600 kg | ×1.53 | $920M | $3.31T |
| 5× | 1,500 kg | ×2.70 | $1.62B | $5.83T |
| 10× | 3,000 kg | ×4.14 | $2.48B | $8.94T |
| 50× | 15,000 kg | ×11.16 | $6.7B | $24.11T |
| 125× | 37,500 kg | ×19.64 | $11.78B | $42.42T |
| 250× | 75,000 kg | ×25.91 | $15.55B | $55.97T |
Oni Tiger income by mutation
At base weight (300 kg). With two mutations the wiki disagrees with itself on whether they add or multiply, so both are shown.
| Mutation | If they add | If they multiply |
|---|---|---|
| None | $600M/s | same |
| Silver | $720M/s | same |
| Golden | $1.5B/s | same |
| Rainbow | $2.1B/s | same |
| Golden + Bloom | $1.65B/s | $1.88B/s |
| Rainbow + Parasite | $3.3B/s | $6.3B/s |
Worked example: a Golden Oni Tiger at twice base weight
- Weight ratio: 600 kg ÷ 300 kg = 2.
- Size multiplier: 237/60 = ×1.5333.
- Golden multiplies by 2.5, so income = $600M × 1.5333 × 2.5 = $2.3B/s, which is $8.28T per hour.
- Saving for the Hacker Treadmill ($3T) from $0 with only this pet: 21m 44s. A plain Oni Tiger at base weight would take 1h 23m.
Common mistakes
- Expecting income to double with weight. A Oni Tiger at 600 kg earns $920M/s, not double the base. To double its income it has to weigh about 3.08 times the base: 924 kg.
- Forgetting the 125× soft cap. For a Oni Tiger that is 37,500 kg. Past it, extra weight still helps but much less: doubling from 125× to 250× adds only about 32%.
- Assuming mutations multiply. A Golden + Bloom Oni Tiger at base weight earns $1.65B/s if mutations add (the wiki calculator's rule) and $1.88B/s if they multiply. Plan with the lower number until it's confirmed.
- Counting the x2 gamepass twice. Tick it once. If you copy this pet's income into the treadmill calculator with x2 already included, leave x2 unticked there.
