The complication is one episode with two versions, plus several releases that package the same material differently. The number zero does not make Zero the starting point. Nor does a box marked Complete necessarily contain both television series. Here is a spoiler-light route through the anime, with the optional stops and edition differences explained.

Finish the original series before beginning Zero

Start with Steins;Gate (2011), episodes 1–24, including the normal episodes 23 and 24. The original introduces Okabe’s laboratory, its improvised experiments and the people whose relationships give those experiments weight. You can meet that cast in the order the story presents them, without learning its later turning points from a timeline diagram.

Keeping the final two episodes together also preserves the original series as one dramatic experience. Pausing just before its ending to watch another 23-episode show changes that experience substantially. Our recommendation is to let the first story finish, then examine the alternative that Zero explores. It is an editorial recommendation for newcomers, rather than an official declaration that every other arrangement is wrong.

  1. Watch Steins;Gate, episodes 1–24.
  2. If you want the original anime’s afterstories now, add Egoistic Poriomania and then Load Region of Déjà Vu. Both are optional stops in this recommended route.
  3. Watch episode 23β, also labelled 23 beta or Divide by Zero.
  4. Watch Steins;Gate 0, episodes 1–23.
  5. Add Zero’s unaired Valentine’s episode afterward if you want its bonus story.

The episode counts come from the releases themselves. Nitroplus’s original Complete Blu-ray announcement separates the 24 television episodes, the unaired Poriomania episode and the film. The official Zero disc inventory lists 23 television episodes and an additional unaired episode. Those are two different sets of extras, not one continuous season count.

First watch the original 24 episodes, then 23 beta and Zero episodes 1–23. Episode 25 and the film are optional original-anime afterstories; Zero has its own bonus.
A first viewing follows the complete original before the alternate branch. The optional film route stays attached to the original anime. Original diagram based on the official release inventories; it shows viewing order, not a literal timeline of events.

Episode 23β opens a different branch

The original episode 23 is part of the route to episode 24. Episode 23β revisits that point with a different development and provides the entry into Zero. They have different jobs. Watching the normal episode 23 and continuing to 24 does not make you miss the beta episode; you can return for β once you have finished the original.

The Japanese subtitles can help when a catalogue is unclear. The normal episode is 境界面上のシュタインズゲート, while the altered version is 境界面上のミッシングリンク. English listings commonly use Open the Steins Gate for the former and Divide by Zero for the latter. The official Standard Edition description specifically identifies the modified episode 23 as the one leading into Zero.

Look for the beta symbol, the word beta, or that separate title. Its position in a service’s episode menu can vary, so an item numbered 23 alone is insufficient to identify the version. You do not need to read the synopsis to solve this; a detailed description of either episode can reveal the very choice you are about to watch.

If you have already completed the original and want the next main television story, select 23β and then Zero. There is no need to replay the whole original immediately. If your service lacks the special, the original remains a complete first viewing; check another lawful listing or the contents of an available edition before assuming that the missing item is a new season.

The film and bonus episodes are separate viewing choices

Egoistic Poriomania, often numbered episode 25, follows the original television story. Watch it after episode 24. If you also want the 2013 film, Steins;Gate: The Movie − Load Region of Déjà Vu, place it after that bonus episode. The film belongs with the original anime’s aftermath; it is not a compilation of Zero’s television episodes.

You can therefore choose between a focused television route and a fuller visit with the original cast. For the focused route, move from the original finale to 23β and Zero. For the fuller route, take the Poriomania and film detour first. Calling these stops optional describes their place in this recommendation, rather than a judgment that their stories have no value. They may be exactly what you want if you are more interested in spending time with the characters than moving straight into the next series.

Zero has its own unaired bonus, Valentine’s of Crystal Polymorphism, sometimes accompanied by Bittersweet Intermedio in English listings. Save it until after Zero’s episode 23. KADOKAWA’s Zero box specification lists this Valentine’s episode separately from the television run. A catalogue that calls it episode 24 is counting that bonus; it has not discovered an additional main-series finale.

The short Cognitive Computing animations are another optional extra. Nitroplus lists the IBM collaboration among the original box’s bonus videos. Leave these shorts until after the original if you want more of its cast. You do not need to assemble promotional shorts, game opening videos and event recordings before beginning Zero.

Keep the interleaved order for a deliberate rewatch

The familiar alternative is original episodes 1–22, then 23β, then Zero episodes 1–23, and finally the original episodes 23–24. Its appeal is clear once you know the story: you spend a full series exploring the alternate branch before returning to the original conclusion. That can change which connections feel most immediate when you reach the final pair.

It also postpones that conclusion for an entire television run. On a first watch, this makes Zero a long interruption at the moment the original is approaching its payoff. On a rewatch, you already know that payoff and can choose to examine the connections instead. The benefit depends on what you want from the viewing, rather than on a claim that rearranging episodes reveals the only correct version.

Think of this as an interleaved route across related branches, not a simple calendar chronology. The original ending, its alternate episode and Zero are precisely why an ordinary earliest-to-latest list is awkward here. If you follow the alternative, keep the normal episode 23 in the final two-episode block; β does not remove it from the story you eventually finish.

Check which series a Complete box contains

Two official Japanese products illustrate the problem with buying by the word Complete. The original Steins;Gate Complete Blu-ray BOX Standard Edition, described on the official Zero site, contains the original 24 episodes, Poriomania, the film and the modified episode 23 leading into Zero. That modified episode is a bridge. Its inclusion does not mean that the box also contains Zero’s 23-episode television series.

The 2022 Steins;Gate 0 Blu-ray BOX contains Zero’s 23 episodes, the Valentine’s bonus, the original series’ 23β and the original series’ episode 24. That last item is a repeat of the original finale included as an extra, not a newly numbered Zero episode. KADOKAWA explicitly labels it as an episode of the first anime. The distinction explains both what a buyer receives and why adding up every numbered item can produce a misleading total.

These Japanese specifications are useful content records, not recommendations to import a particular set. Before buying an edition you can actually obtain, check its language tracks, subtitles, disc compatibility and included titles. A collection may cover the viewing route you want without offering the English version you need. Choose from the stated contents rather than treating a franchise-wide label as a guarantee.

Choose access and games after choosing the anime route

There is a current reason to revisit the original’s listing. On 19 October 2026, Crunchyroll announced the English dub of all 24 original episodes. That announcement covers the original television run. Check the separate listings for Zero, 23β, the bonus episodes and the film in your region; it does not establish that every item is included wherever you subscribe.

For a new subscription, identify the block you intend to watch and the language you want before paying. If you are comparing services more broadly, our Crunchyroll and HIDIVE comparison explains the practical subscription choices. A service carrying the original can be enough to start, even if you decide where to find the film only after finishing it.

The games are a separate way to experience the story. Spike Chunsoft describes ELITE as an adventure visual novel using anime footage and newly animated sequences, with choices and branching endings. Its animation does not turn it into another television season to insert between episodes. Choose it if you want an interactive version, rather than as a prerequisite for understanding the anime.

The same format distinction matters for RE:BOOT. Spike Chunsoft’s announcement describes a reworked game with new graphics and narrative content, scheduled for North America and Europe on 29 October 2026. It is not an announced replacement television cut. You can start the original anime now, finish its ending, and decide afterward whether exploring another medium is how you want to return to Okabe’s lab.
