Gakumas Gacha: Rate Table, the 10-Pull Guarantee and the Spark
Gakumas gacha pulls two things: P-idols (the idol cards you produce with) and support cards. Per the in-game rate table (compiled from Japanese community sources — always reconfirm the table on the live banner): SSR 5%, SR 17%, with the remaining 78% landing on the lowest rarity, PR. Two safety nets exist: every ten-pull guarantees at least one SR (ten separate single pulls do NOT carry this guarantee), and every pull grants 1 exchange point — reach roughly 200 points and you trade directly for a P-idol or support card from that banner's exchange list. That is what the community calls the spark.
The Rate Table and What It Means
Three numbers to remember — from the in-game rate table, compiled from Japanese community sources, and worth reconfirming in-game on the banner you are pulling:
- SSR — 5%
- SR — 17%
- PR (lowest) — 78%
By gacha standards those are generous rates. But do not read "5%" as "an SSR every 20 pulls" — each pull is independent, and bad luck stays bad luck. The thing that actually guarantees you an SSR is the spark, not the 5% figure.
The Two Guarantees: the Ten-Pull and the 200 Spark
The ten-pull SR guarantee. A single ten-pull always contains at least one SR. The trap: doing ten single pulls does NOT count — always pull in tens.
The spark — about 200 pulls. Each pull awards 1 exchange point. Once you hit the required total — the figure Japanese players report is 200, so confirm it on the banner itself — you trade for a P-idol or support card on that banner's exchange list. This is the only certain route to a specific SSR.
One caveat that costs people cards: when a banner's exchange line-up is refreshed, your points can reset. If you are close to 200 and a rotation is coming, consider spending the last pulls before the counter wipes.
What a New Player Should Pull For
Both live in the same box, but they play different roles: a P-idol is who you produce, while a support card raises the quality of EVERY run you make afterwards. Japanese players typically tell newcomers to start with at least two SSR support cards, because they pay off no matter which idol you raise.
Only then chase the P-idol you actually like, or the one the current contest season's plan calls for. Once you are settled in, the low-risk way to spend jewels is simple: bank enough for a full 200 pulls before the banner you care about arrives.
Tracking Your Spark Progress with the Tool
Counting 200 pulls in your head across several banners is easy to get wrong, and getting it wrong costs you an SSR. GameVika's Gacha Tracker holds the number for you: how many pulls you have made, and how many remain until the spark exchange.
Two habits that prevent regret: (1) before pulling, ask whether the thing you want is on that banner's exchange list — that is the only thing you are guaranteed to walk away with; (2) always check the banner's end date, because exchange points can reset when the line-up refreshes.

Frequently asked questions
What are the Gakumas gacha rates?
Per the in-game rate table, compiled from Japanese community sources (always reconfirm in-game): SSR 5%, SR 17%, and the remaining 78% for the lowest rarity, PR. By gacha standards those are fairly generous.
How many pulls is the spark?
Around 200 pulls — that is the point threshold Japanese players commonly report, so confirm it on the live banner. Each pull grants 1 exchange point; once you reach the total you trade for a P-idol or support card from that banner's exchange list. Note that points can reset when the exchange line-up is refreshed.
Does a ten-pull guarantee anything?
Yes: a ten-pull guarantees at least one SR. Ten separate single pulls do NOT count, so always pull in tens. SSR has no per-pull guarantee — for certainty you rely on the 200 spark.
Should I prioritise P-idols or support cards?
New players should secure at least two SSR support cards first: they improve every future run no matter which idol you raise. After that, chase the P-idol you like, or the one that fits the current contest season's plan.
