Gacha Rates, Banners & Probability

Most sites tell you which cookies to chase. This one tells you what chasing them costs.

Rates at Gacha Level 10

| Rarity | Rate | Cookies in pool | Per named cookie | |---|---|---|---| | TSSR | 0.05% | 3 | 0.017% | | SSR | 1.20% | 21 | 0.057% | | SR | 7.00% | 15 | 0.467% | | R | 13.00% | 12 | 1.083% | | U | 18.00% | 11 | 1.636% | | C | 60.75% | 9 | 6.750% |

They sum to exactly 100%, which is a good sign for the source's reliability — though these are community figures, not an official Devsisters disclosure we could locate.

Gacha Level changes the rates

Gacha Level is an experience bar filled by drawing, capped at Level 10, and tracked separately for Cookies and Pets. Two hard gates:

• SSR cannot drop below Gacha Level 4
• TSSR cannot drop below Gacha Level 6

At Level 1 the Premium pool is reported as 82% Common and 18% Uncommon — nothing above that exists yet. So early pulls are not unlucky; they are structurally incapable of producing what you want.

What a specific cookie actually costs

Rates split evenly across each rarity. With 21 SSR cookies, a named SSR is roughly 0.057% per draw — about one in 1,750.

Running that through the binomial maths:

| Target | 100 draws | 90% confidence needs | |---|---|---| | Any SSR (1.20%) | 70.1% | 191 draws | | A named SSR (0.057%) | 5.5% | ~4,000 draws | | Any TSSR (0.05%) | 4.9% | ~4,600 draws |

The reroll planner runs these numbers for any target and draw count.

The caveat that matters

These assume independent draws and no pity system. We could not find a pity or guarantee mechanic documented anywhere. If one exists, every figure above is pessimistic — which is the safer direction to be wrong in, but it is a real unknown.
