Turning report cards into FIFA pack openings: Dutch students installed CijferPacks 20k times in a month, and 7 copycats followed
What it is A Dutch-language Chrome extension that hides new grades on Magister, Somtoday, and Osiris report pages inside FIFA-style card packs, so you only see the score when you open one.
Why it took off Dutch students had been hand-editing "grade pack opening" videos on TikTok for four years. In early October, another project's demo video lit the fuse. This one was the first to put all three grade systems into one extension, a week before its rival shipped, and its own two TikToks pulled 170k views.
CHow to ride it: Don't fight over the Dutch market. Carry the same idea over to other countries' grade systems (Belgium's Smartschool, Germany's WebUntis, France's Pronote) or to mobile, and ship before each local first round of results comes out. Film unboxing-style videos for TikTok yourself.

CijferPacks is a Dutch-only Chrome extension that hides new grades from the Magister, Somtoday, and Osiris school systems inside FIFA-style card packs, so the score only appears when you open one. It launched in 2026 Oct 5, reached 20k users in a month, spent nothing on promotion, and has made no money. It rode a meme Dutch students had been playing on TikTok for four years. Below: how it took off, why it couldn't hold, and where the playbook can go next.
A video with 90k views
On 2026 Oct 4, just after 7 a.m. (Dutch time), a TikTok account with only a few dozen followers, @cijferpacks2, posted a 54-second video captioned "Magister/SomToday/Osiris packopener nu online!" (card openers for all three school systems now live). The footage shows a row of card packs on a grades page; tap one, a player walk-in animation plays, and a card flips over: subject, date, weighting, and the score. That evening it posted again. By Nov 6, the two videos had 93k and 82k views, with 1,703 and 1,477 shares (TikTok, 11-06). Shares are about 40% of likes, the kind of ratio you get when students send the video to classmates.
The most common comments were "Welke extensie" (which extension?), "Wanneer voor Somtoday" (when for Somtoday?), and "ook smartschool please" (Belgium too, please). Some were blunter: "cijferreveal ripoff" (copying Cijfer Reveal), "holy ai" (AI-written?).
The next day, 5 Oct, the extension appeared in the Chrome Web Store. The same day they posted another video captioned "Deel de extensie en laat reviews achter!" (share the extension and leave a review). In the first 4 days after launch, the review count rose from 3 to 43; over the next month it added only 12 more (store review count, 11-06 as of 55 reviews, rated 4.78).
The store reviews sound a lot like the users themselves:
"Pretty fun, though the first pack I opened was a 2.2." (10-09,16 people found this helpful) "Felt less miserable once I got a 4.8." (10-08) "I pulled Diddy." (10-15)
Dutch grades are on a 10-point scale, with 5.5 as a pass. A 4.8 used to be bad news; put it in a card pack with an entrance animation and it becomes something you can screen-record and post to TikTok.

It does one thing: it detects new grades, hides them in a card pack labeled with the subject, and reveals the score only when you open it. Opened cards stay in your collection. No login, no backend; it works on the existing grade page as soon as you install it.
Why this one, and why now
The meme was already there. "Magister pack opening" had been a Dutch TikTok trend for 2022 years. Students hand-edited their grades into FIFA pack-opening clips, and one back then got 370k views on its own (TikTok, @magisterpackopening123,2022-07). For four years people had been making these by hand; nobody had turned it into a tool.
Someone lit the fuse first. At the end of September, EA FC 27 launched and pack-opening content was hot; in early October, Dutch secondary schools began releasing first-round test grades. On Oct 2, another project, Magister Ultimate Team (MUT below), posted a grade pack-opening demo that got 645k views. But MUT's extension didn't reach the Chrome Web Store until Oct 10.
It grabbed the gap that week. In the few days in between, people who had watched the MUT video and searched the store for "magister pack" found CijferPacks first; it had been listed on 10-05. Its title names all three systems at once: Magister and Somtoday are used in secondary school, Osiris in university, so people from every group could find it. Cijfer Reveal and Somtoday Pack Opener, from around the same time, supported only one system each.
It had the lowest barrier. Rival products required sign-ups, coins, or mini-games. This one installed and opened right away, and it had the best reviews in its category (4.78 stars, versus MUT's 4.28 and Cijfer Reveal's 3.65).
The later growth looks more like the whole category rising. In Nov 3 it went from 10k to 20k. It didn't post new videos in those days, but MUT posted another pack-opening video in Nov 2 that got 310k views (TikTok, 11-06). Also, the store only shows approximate counts above 10k, so the jump from "10k" to "20k" may just be crossing a display tier (inferred).
Where the money comes from
No. There are no in-app purchases, no website, and no payment option; the developer looks like a student. These products could monetize by selling card-face skins or player themes, but the users are mostly minors, and selling "pack openings" is close to loot-box gambling. The Netherlands regulates loot boxes relatively strictly by European standards, so that path needs care.
Who it's competing with
| Competitors | Launched | Scale (Chrome Web Store, 11-06) | How CijferPacks differs |
|---|---|---|---|
| Study Tools voor Magister | 2023-04 | 100k users | A Magister power-up tool (themes, grade statistics), no pack opening; the big name in this circle |
| Somtoday Mod | 2024-02 | 70k | Somtoday reskin, no pack opening |
| Cijfer Reveal voor Magister | 2026-06 | 10k users, rated 3.65; also has an Android version | The earliest to gamify grade reveals: spin wheels, boxes, penalty kicks, coins; Magister only |
| Magister Ultimate Team | 2026-10-10 | 10k users, rated 4.28; 5k followers on TikTok | The most elaborate: grades become player cards, with squads, matches, trading, and friends; has a backend, keeps updating, and posts videos |
| Somtoday Pack Opener | 2026-10-07 | 7,000 (11-01 is 4,000) | Somtoday only, and each grade can only be opened once |
| Cijfer Reveal voor Somtoday | 2026-10-06 | 2,000 | Cijfer Reveal's Somtoday version |
| CijferReveal voor SOMtoday en Magister, Somtoday Cijfers, Somtoday Packs, Cijfer Onthuller | 2026-10 to 11 | 0 to 1,000 | A reskin; the last one to appear, 11-05 |
In one month, the same idea showed up seven or eight times, all free. CijferPacks's features could be copied in an afternoon, and after 10-15 it stopped updating, its TikTok frozen at 10-05. MUT is moving toward "the more you play, the more there is," and over time users are more likely to drift that way.
If it were you
C: a clean playbook to learn from, but not a good deal for this one product. The Dutch market is already crowded with seven or eight free options, there's no money to be made, the users are minors, and all you can take away is the idea.
Who it suits: developers who are studying or recently graduated in another country and know that country's grade systems and student TikTok scene well. It suits people who want a practice project they can ship fast and get real users with, or who want to build a student audience to use later for something else.
Who it doesn't suit: anyone who wants to make money from it; anyone who doesn't know local students and can only promote in English-speaking communities; anyone who wants to go head-to-head with MUT and Cijfer Reveal in the Netherlands.
How to do it: Move it to another country's grade system and put the system name in the title. The clearest signal is the comment "ook smartschool please": Flemish secondary schools in Belgium use Smartschool, and they speak Dutch and watch the same TikToks. But by Nov 5, a "Smartschool Punten Case" had already appeared in the Chrome Store (0 users on launch day), so that window is closing. Beyond that are Germany's and Austria's WebUntis, France's Pronote, and moments like "results day" or "admissions decisions" that happen a few times a year when the whole class waits (I haven't verified which countries are still open). You could also cover what it left undone: comments asked "does it work on iPad?", "won't open on my phone", and "Chrome Web Store is blocked on school computers." Mobile and web versions are currently empty.
How to get users: Copy its approach. Before launch, search local TikTok for "<system name> pack opening" or "<system name> reveal" and see whether anyone is hand-editing these already; if so, the demand has been educated. Film two or three pack-opening videos yourself, caption them "now available," and put "search <name> on the Chrome Web Store" in your bio. In the first few days, prompt users to leave reviews to push up the rating count. Posting around grade-release season works best.
When to ship: before the local first round of grades comes out. This Dutch wave came in early October, with the EA FC release at the end of September too. If you miss this season, wait for the next big exam results.
What would mean I got it wrong: (1) if CijferPacks or MUT were still growing in early 2027 and passed 50k users, that would show this isn't a passing fad and there's still room in the Netherlands; (2) if MUT starts selling things without trouble, that shows this audience can monetize, and the rating should go up; (3) the reverse: if the user counts of these projects fall together in December (CijferPacks already fell back once in late October), it means novelty wears off and moving it to other countries would just be one wave.

CijferPacks for Magister, Somtoday and Osiris: why it took off
Bottom line
Dutch high schoolers had been running a "Magister pack opening" meme on TikTok for 4 years (hand-edited clips turning grades into FIFA card packs), and in autumn 2026 a few student devs turned it into an extension that actually works. 2026-10-02 A 645k-view demo video for Magister Ultimate Team lit the demand, and CijferPacks 10-05 was the first to list a version on the Chrome Web Store that supports all three grading systems with pure pack opening. Its own two TikToks pulled 175k views and 3,000+ shares, and it caught the search traffic from the wave. It ran on timing plus organic TikTok spread, not on the product itself, which has no moat. Within a month, 7+ copycats had crowded into the category.
Key facts
- Store: first listed 2026-10-05 (Beijing time), updated to 10-15 1.0.2,3.73MiB, Dutch only, developer email [email protected], not a trader, no website, no in-app purchases, no paid wording in the description (store page, read 2026-11-06).
- User count (data card and chromestore library item_snap): 11-01 to 11-03, from 10,000,11-04 onward 20,000. 4.78,55 ratings.
- extops.dev curve (recorded in the data card at retrieval): 10-08 1k → 10-10 6k → 10-27 10k → 11-03 20k; between 10-17 and 10-25 it dipped to 7–8k. Ratings went from 4 to 3 in the first 43 days, then only gained 12 more over the following month.
- Permissions: the manifest lists only storage / unlimitedStorage, but the privacy disclosure says "Website content". Reading the Magister/Somtoday/Osiris pages is presumably done via content_scripts matches (not counted in the permissions list), so this is not a contradiction (inferred; manifest source not verified).

Conclusion: it did not invent this. Cijfer Reveal June was already out, and MUT's video came 3 days earlier and went viral, but CijferPacks was the first to support Magister, Somtoday and Osiris (university) together, and it does only this one thing: pack opening. Covering all three systems meant the title could be found by three separate groups of searchers.
2. Growth levers (where users come from)
- Its own TikTok account, confirmed: @cijferpacks2 has only 4 videos and 202 followers, but the "Magister/SomToday/Osiris packopener nu online" video from 10-03 has 92,801 views, 4,637 likes and 1,703 shares; the one from 10-04 has 82,454 views, 3,294 likes and 1,477 shares (TikHub, 2026-11-06). Shares run near 40% of likes, which points to students passing it to classmates. The bio says "search CijferPacks on the Chrome Web Store", sending people to a store search.
- Riding the whole meme and the rivals' heat, high odds but not fully verified: the "Magister pack opening" is a TikTok meme that's been around since 2022. @magisterpackopening123 2022-07 has a video with 370K views, and @ibrahd_ 2022-05 has one with 64K, both hand-edited back then. 2026-10-02 MUT posted "Magister fifa packopener" with 645K views, but MUT's extension 10-10 only hit the Chrome Web Store later. In the gap that week, anyone searching "magister pack" in the store first found CijferPacks, which 10-05 listed. Now the store's "related extensions" section lumps these together (MUT is ranked #0), and they're all funneling traffic to each other.
- Review prompting, confirmed: the caption on the 10-05 video read "Deel de extensie en laat reviews achter!" (share the extension and leave a review). Ratings went from 4 to 3 in the first 43 days, then only gained 12 more over the following month.
- Word of mouth at school, inferred: users are Dutch high schoolers and university students using Magister/Somtoday in Chrome. One person in a class installs it, and others follow. On 11-03 the count jumped from 10k to 20k, and no new CijferPacks video of its own turned up that day; in the same period MUT posted a 11-02 video with 309k views. So the jump more likely reflects the whole category getting pushed, not CijferPacks' own action (inferred). Also, the user count above 10k is approximate, so 10k to 20k may just be crossing a display tier.
- Not found: ads, media coverage, X or Reddit discussion (x-radar search for "magister pack" over the last 60 days returned 0 posts; Jina search of Reddit found no relevant threads).
3. Why it took off
- The meme exists, so the demand was already educated: FIFA/FC card opening is a ritual Dutch teens know well. Since 2022 people have hand-edited grades into pack-opening videos, and the extension automates it, so anyone can open their own and screen-record it for TikTok. The product is itself a content tool, so it spreads itself.
- Timing: EA FC 27 launched in late September, when pack-opening talk was hot; early October is when the Dutch school's first round of test grades came out; MUT's viral video in 10-02 lit the demand.
- Took the open slot in the store: listed 10-05, 5 days before MUT reached the Chrome Web Store; the title spells out all three system names, "Magister, Somtoday en Osiris", so three groups of searchers can find it. Reach is broader than Cijfer Reveal or Somtoday Pack Opener, which each support a single system.
- Simple: no login, no backend, no account credentials; install it and open packs on the grades page, the lowest barrier. Rating 4.78, among the best reviewed in its category; MUT is 4.28, Cijfer Reveal is 3.65.
4. Differentiation
- Compared with Cijfer Reveal: one extension covers all three systems, and it does only pack opening, with no coins or mini-games, so it's lighter.
- Compared with MUT: MUT builds a "grades version of FUT" (teams, battles, trading, friends); CijferPacks only does the walkout animation at reveal, so it's simpler but easier to replace.
- This differentiation explains why it captured traffic in this window, but it can't hold it. The features can be copied in an afternoon, and by November new reskins like Somtoday Packs and Cijfer Onthuller were already out. It hasn't updated since 10-15, and its TikTok has gone quiet since 10-05; MUT keeps updating and posting. Long term, users are more likely to drift toward products like MUT that keep adding things.
5. Who's watching, who's copying
- Revenue: none. No in-app purchases, no website, and no revenue posted on TrustMRR.
- Visibility: only spread within Dutch student TikTok circles; no media or large X accounts have covered it.
- Copycats: plenty. CijferReveal's Somtoday version, Somtoday Pack Opener, CijferReveal (js664), Somtoday Cijfers, Somtoday Packs (11-05) and Cijfer Onthuller all appeared the same month.
6. What to take away
- "Turn an existing hand-made TikTok meme into a one-click tool": search TikTok for template memes like "X pack opening" or "X reveal", find the ones people keep hand-editing that nobody has turned into a tool yet. The result is the tool creators need to make their content.
- Put every platform name you cover in the title to catch store search.
- The same idea transfers to grade systems and learning platforms in other countries: Germany's WebUntis, Belgium's Smartschool, the UK's Arbor, the US's PowerSchool / Canvas, or moments like "exam results out" and "offer reveal".
- Monetization is an open gap: the student audience could buy skins or player-card themes. But selling "pack opening" to minors calls for caution given loot-box-style regulation, and the Netherlands is strict about loot boxes.
VII. What I'm still unsure about
- The direct cause of 11-03 jumping from 10k to 20k (possibly carried by MUT's video, or possibly just crossing a display tier).
- Retention: from 10-17 to 10-25 it dipped once, so some people installed and then uninstalled. Not every result holds up, and it's unclear whether uninstalls spike once the novelty wears off.
- Who the developer is (only a gmail address and the cijferpacks/privacybeleid repo on GitHub), and whether they have other projects, is unknown.
- The original manifest content_scripts was not seen, and how "automatic detection of new grades" is implemented was not verified.
- Whether there is an app with the same name on Play / the App Store: only confirmed that Cijfer Reveal has an Android version (AppBrain); our googleplay library does not include it.
