Odds and How It Works

Last updated: October 16, 2026

Packs cannot be bought, and buying anything never changes any odds.

In "Scoop and Serve", only two things have a random result: the free sticker packs and scoop mutations. Neither can be obtained with money, and no purchase, amount spent or offer changes their odds. Everything that is sold has fixed contents. The Japanese version prevails.

1. Sticker packs

How to get them (all free)

Sticker packs are never sold and never come from offers, the paid pass (Gold Stamp) or coins.

Up to 2 packs can be opened per day (days change at 4:00 a.m. Japan time). Packs beyond that are kept and can be opened on the following days.

Odds

A season's album (8 weeks) has 9 pages of 9 stickers (per page: 4 common, 2 uncommon, 2 rare, 1 special), 81 in all. A pack holds 3 stickers, always from these 81.

Duplicates and the exchange

A duplicate turns into sticker shards. Shards can be exchanged for one sticker of your choice, or for a pack (30 shards).

At the end of an album season, leftover shards turn into 2 free coins each (up to 1,000 coins).

Gold Stamp holo stickers

The Gold Stamp (the paid season pass) gives 4 holo stickers per stamp-rally season (4 weeks), with fixed contents. An album season (8 weeks) spans 2 stamp-rally seasons, so each album has 8 on a separate holo strip, outside its pages: numbers 1–4 come from the Gold Stamp of its first season and 5–8 from its second, so buying both never gives the same holo sticker twice.

They never come from packs and are not among the 81 stickers above, the pages or the album completion. What a pack contains, the first-pack guarantee included, is decided from the 81 pack stickers only. Owning holo stickers therefore changes no pack odds, no choice of stickers you do not own yet and no page reward: nothing sold changes any probability.

Any holo sticker of the current album can also be obtained for free at the exchange for 60 shards each.

Album seasons

The sticker album starts over every season. When an album season (8 weeks) ends, its pages and its holo strip are replaced by a new album. The stickers collected in the album that ended are kept as a record in the save data. Stamp-rally rewards not claimed by the end of a season are claimed automatically; their holo stickers go into that season's album before it is recorded.

2. Scoop mutations (Sparkle, Gold, Aurora)

Every new scoop (a dropped scoop or the result of a merge) gets one draw. A merged scoop keeps the better mutation of the two it came from, or the newly drawn one if that is better. Serving a mutated scoop earns more coins. Mutations never change how hard a level is. In the daily challenge and in replays of levels already cleared they are only visual.

Gold0.6%×520
Aurora0.06%×1020

First appearances: level 5 always shows the first Sparkle scoop and level 20 the first Gold scoop, once, at a fixed moment. These introductions are scripted, not random, and come in addition to the odds above.

Sparkle Festival

From Wednesday to Friday of the second and fourth week of each 4-week season, all mutation odds are multiplied by 2. The App shows the dates (example: Sparkle during the festival = 3% × 2 = 6%).

3. Money and odds

These are the exact values the App's program uses. This page is updated before any change.
