Jump+ Jumble Rush Ends September 17 After 56 Days' Notice: Japan-Only, Never Global, and a Refund Japanese Law Requires
Jump+ Jumble Rush ends service on September 17, 2026, and because the game only ever shipped in Japan, that date closes it everywhere. There was no global build, no Western publisher and no second region to fall back on. This is a single-region shutdown that is also a total one.
Bandai Namco Entertainment published the notice on July 23, 2026 (JST), which gives players 56 days. Several English outlets carry July 24 instead. That is their own US publication timestamp, not an operator action: the official account, 4Gamer, Denfaminicogamer, Dengeki Online and gamebiz all filed on the 23rd.
Sales of Prism, the paid app-exclusive currency, ended the same day the notice went up. The servers keep running for another eight weeks, so the money stopped on day zero while the game did not. Unused balances are covered by a refund the operator does not get to decline: the official site commits to a notice under Article 20, Paragraph 1 of Japan's Payment Services Act.
The shutdown schedule, with the dates that are actually published
| Date (JST) | Event | Tier |
|---|---|---|
| July 3, 2025 | Title revealed | T2 |
| August 12, 2025 | Pre-registration opens | T2 |
| September 24, 2025 | Launch, Japan only, iOS and Android | T1 |
| July 23, 2026 | End of service announced. Prism sales end the same day | T1 |
| July 23 to September 17, 2026 | Held Prism stays spendable, game stays playable | T1 |
| September 17, 2026 (Thu) | Service ends at shutdown maintenance | T1 |
| After September 17, 2026 | Refund notice published under Payment Services Act Art. 20(1) | T1 |
No clock time appears anywhere in that schedule. The official site frames September 17 as an end date and a maintenance, and no hour has been disclosed at any tier, so treat the last playable moment as unspecified rather than assuming a midnight or a noon cutoff.
The last row is the one most coverage gets wrong. The refund notice is due after the shutdown, in the operator's own wording: 払い戻しに関するお知らせは、サービス終了となる9月17日以降に掲載予定. A player who checks the site on September 17 for refund instructions is checking a day early.
Prism died on day one of the notice
The line on the official site reads 有償アプリ専用通貨の販売を終了いたしました, meaning sales of the paid app-exclusive currency have already ended. That took effect July 23, simultaneously with the announcement. 4Gamer confirms the two events landed together.
Prism bought before that cutoff stays usable to the end. There is a 56-day window to spend a balance down, and there is no way to add to it. That sequencing is the correct one, and it is worth naming plainly because the reverse pattern, taking payments while a closure is already scheduled internally, is the version players usually complain about.
What has not been published is any farewell campaign, any final content update or any giveaway of premium currency to burn the balance on. As of August 1, 2026, the notice contains a schedule and nothing else.
The refund is a statute, not a courtesy
This is the fact no English-language page on the closure currently carries. Bandai Namco is not offering goodwill. Under Article 20, Paragraph 1 of the Payment Services Act (資金決済に関する法律第20条第1項), an issuer of a prepaid payment instrument in Japan that terminates its service is required to refund unused balances to holders. Prism is such an instrument. gamebiz reports the Article 20(1) notice as a scheduled item on the termination timetable, not as a possibility.
That is the structural difference between a Japanese shutdown and most Western ones, where unused paid currency is typically written off with a line about it having no cash value. Here the obligation is external to the publisher.
Three things about it are still unpublished:
- The rate. No conversion from Prism to yen has been stated.
- The procedure and the claim window. No form, no deadline, no cap.
- Any minimum threshold. Nothing published either way.
The one instruction that has been issued is negative and matters more than it looks: players who bought Prism are told not to uninstall the app until the refund process is complete. Since the refund notice only appears after September 17, that means keeping a dead game installed past its own shutdown, on a phone, indefinitely, until instructions arrive.
It was Japan-only, and that was never going to change
Jump+ Jumble Rush released on September 24, 2025 on the Japanese App Store and Google Play. No other storefront ever carried it. Pre-registration, which opened August 12, 2025, was a Japanese campaign. There was no announced global build in development, no soft launch elsewhere and no publisher lined up for one.
That is why the phrasing in some coverage is misleading rather than merely incomplete. Anime News Network describes the platforms as iOS and Android without a region. Siliconera tags the story for Asia, Europe, Japan and North America, which reads to both people and crawlers as a multi-region product. GamingOnPhone is the only English page that puts the restriction in its headline.
For a reader outside Japan the practical answer is short: there was never anything to lose access to, and there is nothing to download before the 17th either.

The launch PV published on release day, September 24, 2025. The service runs 358 days from that point.
WonderPlanet Inc. (ワンダープラネット株式会社) developed it. Bandai Namco Entertainment handled production and distribution, the 製作・配信 credit, and Shueisha supplied the IP through Shonen Jump+. WonderPlanet published its development credit on July 4, 2025, the day after the title reveal. None of the three English pages ranking for this closure names the developer at all.
The genre is more specific than the "tower defense" label most coverage reached for. 4Gamer's reveal piece gives the official term as 漫画コマ型タワーオフェンスゲーム, a manga-panel tower offense game, in which units advance a front line inside comic frames rather than holding a lane against incoming waves. The panel conceit is the reason the game existed: it was built for the Shonen Jump+ 10th anniversary project, marking the service that launched September 22, 2014.

The roster drew on 17 Shonen Jump+ series, a count Anime News Network supplies and Final Weapon corroborates. Series named across coverage include SPY×FAMILY, Chainsaw Man, DAN DA DAN, Kaiju No. 8, Aharen-san wa Hakarenai, Magilumiere Co. Ltd., Ron Kamonohashi: Deranged Detective and Summer Time Rendering. Japanese players shortened the title to ジャンブラ.

On the exact title: it is Jump+ Jumble Rush, 『ジャンプ＋ジャンブルラッシュ』. The plus belongs to Jump+, the manga service. It is not a separator between two words.
Nothing is being preserved
There is no offline version, no single-player build, no archive and no preservation commitment. That is not a soft "has not yet announced." Nothing in the notice contemplates one, and no coverage at any tier reports one.
The notice also says nothing about player data, in either direction. It does not promise retention and it does not announce deletion, so neither should be stated as fact here.
No store delisting date has been published either, which leaves the window for a final Japanese-account download undefined. The precedent for a Shueisha crossover title is not encouraging: Jump Force, released 2019 and discontinued in 2021, was fully delisted from digital storefronts on discontinuation. The other Jump mobile precedent is Jumputi Heroes, the Weekly Shonen Jump 50th anniversary title that ran from 2018 until service ended March 27, 2024 under LINE Yahoo.
No reason for the closure has been given. The notice uses standard termination language and stops there. Revenue estimates for the title circulate on sell-rank sites and revenue-check video channels; none of them traces to the operator or to a reputable analytics vendor, so no figure appears in this article.

The refund rate and claim window. Article 20(1) obliges the refund but does not set the terms. The notice due after September 17 is where a Prism-to-yen rate, a claim deadline and a procedure would appear. Until it posts, a spender knows only that something is owed.
A store delisting date. None is published. Whether the app disappears from the Japanese storefronts before September 17 or after it determines whether a lapsed player can reinstall to spend a balance down.
A shutdown clock time. The official schedule names September 17 and a maintenance, with no hour. If Bandai Namco publishes one, the last playable moment moves from unspecified to exact, and it may well fall on the 16th in practice.
