BAIBAI!
Odds & How It Works
(Same text in the sticker book "ⓘ Odds" sheet and on the web at /odds. Numbers come from StickerTables in DopaMeta and from Tuning.json; update this page in the same change if they move.)
Sticker packs in BAIBAI! are free rewards you earn by playing. They cannot be bought. Watching ads or buying anything never changes the odds.
1. How to get packs
Clearing a song, your first ★★★ on a song, the Daily Song, finishing all daily missions, weekly missions, and levelling up.
2. What is inside
Each pack contains one sticker.
Rarity
| Rarity | Chance |
|---|---|
| Common | 55% |
| Uncommon | 25% |
| Rare | 13% |
| Epic | 5.5% |
| Legendary | 1.3% |
| Secret | 0.2% |
- Guarantee: if 9 packs in a row had no Epic or better, the 10th pack is always Epic or better. That pack's odds are Epic 78.57% / Legendary 18.57% / Secret 2.86%.
Which page
- After the rarity is chosen, there is a 50% chance the sticker comes from the page of the song you earned the pack on, and a 50% chance it is picked evenly from the other 7 pages.
- Every page has 5 Common, 3 Uncommon, 2 Rare, 1 Epic, 1 Legendary and 1 Secret sticker.
Chance of one specific sticker (normal pack)
| Rarity | A sticker on that song's page | A sticker on another page |
|---|---|---|
| Common | 5.5% | 0.7857% |
| Uncommon | 4.1667% | 0.5952% |
| Rare | 3.25% | 0.4643% |
| Epic | 2.75% | 0.3929% |
| Legendary | 0.65% | 0.0929% |
| Secret | 0.1% | 0.0143% |
Formula: song's page = rarity chance × 0.5 ÷ stickers of that rarity on that page; other pages = rarity chance × 0.5 ÷ stickers of that rarity on the other 7 pages. Packs not tied to a song page (e.g. daily rewards) pick evenly from all pages (e.g. one Common = 1.375%).
Finish
| Finish | Chance |
|---|---|
| Matte | 70% |
| Puffy | 20% |
| Glitter | 8% |
| Holo | 2% |
The finish is rolled separately from the rarity.
3. Duplicates (Kirakira)
- A duplicate turns into Kirakira: Common 5 / Uncommon 10 / Rare 25 / Epic 60 / Legendary 150 / Secret 400.
- A duplicate with a better finish upgrades yours to that finish. Otherwise, every 3 duplicates raise its finish one step (Matte → Puffy → Glitter → Holo).
- Craft any sticker you want with Kirakira: Common 50 / Uncommon 100 / Rare 250 / Epic 600 / Legendary 1,500 (Secrets cannot be crafted).
4. Fixed stickers
Stickers from achievements, the Season Pass and purchases are always fixed — never random. Season Pass stickers arrive in Holo. The same stickers can also be earned free from packs or crafted.
5. Page rewards
Collect a page's 12 regular stickers (Secrets not needed) to get a theme or a character plus 1,000 coins. Coins can only be used in the game and can never be bought.
6. Mutated balls
Every time your balls split, each split has these chances to create a mutated ball (a split on a JUST beat rolls twice):
| Mutation | Chance | Damage |
|---|---|---|
| Gold | 2% | ×20 |
| Rainbow | 0.25% | ×50 |
| Galaxy | 0.03% | ×100 |
The "Gold Rush" card and the character Kira double these chances. They are gameplay effects and cannot be bought.
