The red carpet in the middle of the map is where Brainrots are offered for in-game cash. A purchase is not secured until the unit reaches your base. Stay with a contested buy instead of walking away at the prompt.
Read four things before you spend:
- The full character name. Trippi Troppi is not Trippi Troppi Troppa Trippa, and Los 67 is not 67.
- The price on that copy.
- The cash per second that copy displays, including its mutation and traits.
- Whether your next Rebirth panel names that character.
Empty slot or replacement
For an empty slot, a simple payback is price divided by displayed cash per second. A reported Common Noobini Pizzanini at 25 cash and 1 per second pays back in about 25 seconds if it earns continuously and is not stolen.
If the slot is full, subtract the income of the unit you would remove. A purchase that does not raise income is not an income upgrade. It can still be worth buying when the Rebirth menu requires that exact name.
Reported early reference pairs
These are published base references, not a live shop. Keep each price with the income it was published beside. Do not mix an old price with a later income.
| Brainrot | Reported rarity | Reported price | Reported base income |
|---|---|---|---|
| Noobini Pizzanini | Common | 25 | 1/s |
| Tim Cheese | Common | 250 | 3/s |
| Fluriflura | Common | 500 | 5/s |
| Trippi Troppi | Rare | 2,000 | 15/s, with a 15-20/s range in one broad list |
| Gangster Footera | Rare | 4,000 | 30/s |
| Glorbo Fruttodrillo | Legendary | 200,000 | 750/s |
| Orangutini Ananassini | Mythic | 400,000 | 2,100/s |
Gangster Footera is a useful early comparison because the same 4,000 and 30/s pair shows up in character references and in a simple payback example. Trippi Troppi's income has also been written as a range. If your panel shows another number, use the panel.
What not to wait for
An empty base does not need a Secret. Fill slots with units you can afford, keep Rebirth requirements, and replace the weakest earner when the extra income is real. The payback calculator runs the minute-based form of this check when you type the offer yourself.
Higher-tier conflicts are large enough to matter. La Vacca Saturno Saturnita is reported at 80 million cash and 325,000/s in a later character reference, and at 50 million and 250,000-300,000/s in older guides. Strawberry Elephant and Skibidi Toilet have competing hundreds-of-billions prices. Budget from the copy in front of you.
