Both of these are free, anime-styled, cosmetic-gacha riichi clients with full English support, which is exactly why they get confused for each other. They’ve converged on the same shape of product. The differences that actually matter are narrower and more specific than “which one is better,” so this article skips the broad strokes and goes axis by axis.
I play Mahjong Soul myself, including the browser version, so the sections on its UI, matchmaking, and rank ladder draw on hands I’ve actually played. I haven’t put comparable hours into Riichi City; where this article covers its teaching system, gacha economy, and community, that’s built from official specs and from community reviewers who have logged serious time on it, and I flag it as such along the way.
If you also want Tenhou in the picture, the hardcore, Japanese-only competitive standard, read our three-way platform comparison instead. This article assumes you’ve already ruled Tenhou out, which is the reasonable call for most beginners, and want the direct answer between the two apps that are actually competing for your install.
The short answer
Choose Mahjong Soul when matchmaking speed outweighs hand-holding. Its player base is the largest English-speaking crowd in riichi mahjong, so you’ll get matched fast against people near your skill level, no matter what rank you’re at.
Choose Riichi City when you need the app to teach you. Between the two, its built-in lesson system does the most instructional heavy lifting, and free players get treated more generously in its gacha economy.
| You are… | Play |
|---|---|
| A rules-shaky beginner who wants to be taught step by step | Riichi City |
| A beginner who mainly wants to jump into games and find opponents fast | Mahjong Soul |
| Someone who cares about the anime characters and voice-line content around the game | Mahjong Soul |
| Someone who wants a friendlier free-currency drip and doesn’t mind a smaller pool | Riichi City |
With the summary out of the way, everything below unpacks why, starting with the full side-by-side.

UI, UX, and platform support
Both apps are unapologetically anime: character portraits, voice lines, event collaborations. Neither hides this behind an option you can toggle off. It’s most of what you’ll be looking at between hands on either platform.
Where they diverge is in what the interface is actually built to do. Mahjong Soul’s interface is built around getting you into a ranked match quickly: menus, match flow, and scoring displays are all readable enough that most people land in their first comfortable game without needing to look anything up elsewhere. Riichi City’s interface carries the same competence, but it also has something Mahjong Soul’s doesn’t: a structured onboarding flow that sits on top of the regular UI and walks a genuine newcomer through the mechanics step by step, rather than just getting them to a table.
Device support is nearly identical between the two, and this is one axis that genuinely won’t decide your pick. Both run on browser, iOS, Android, and Steam, and both play as landscape-only games on mobile, following the standard mahjong-tile-table layout. Mahjong Soul adds a dedicated Windows client on top of that list, and it shares one account across every platform, so a game started on your phone on the train can be picked back up at your desk without losing any progress. The one edge case: if you specifically want a native Windows client outside of Steam, Mahjong Soul is the one that offers it.
Player pool and matchmaking speed
This is Mahjong Soul’s clearest structural advantage. It has the largest English-speaking population of any riichi platform, and that shows up directly in matchmaking speed: a bigger pool means faster matches and, just as important, more opponents actually sitting at your skill level rather than a queue padded out with mismatches.
Riichi City’s pool is smaller overall and skews heavily toward Japanese-speaking players. The clearest evidence for this comes from a detailed multi-client review, written by the player who took second place in Riichi City’s own 2025 Tenkaichi tournament. He had every reason to go easy on the platform whose event he’d just done well in — instead, his write-up points out that strong Western players often can’t find each other in the queue, since there simply aren’t enough of them online at the same time. For a rules-shaky beginner this barely matters; you’ll still find games. For a competitive player hunting well-matched opponents at the top of the ladder, the gap is real.
Gacha and monetization
Neither platform is pay-to-win. On both, money buys characters, outfits, and decorations, never an edge at the table. The difference is how each treats a player who never opens their wallet.
Mahjong Soul keeps its free currency tap running slow. Unlocking everything a favorite character wears without spending is a long grind, and whatever pace of pulls you start with tends to thin out fast once the early-game bonuses run dry. Riichi City is the more generous of the two: a free player who logs in regularly can expect roughly a ten-pull’s worth of currency each month, well above what Mahjong Soul gives away for free.
That free-side generosity doesn’t make Riichi City the cheaper platform for someone determined to spend, though. On the US App Store, the single largest purchase available runs $49.99 on Riichi City versus $79.99 on Mahjong Soul, and both charge $4.99 for their monthly pass (Fortune Charm on Mahjong Soul’s side). But that $49.99 figure is a single-item cap, not Riichi City’s real spending ceiling: when a full crossover event drops, like the 2025 Akagi collaboration, players stacking every piece of the tie-in cosmetics have reported the total running to roughly $400. Assembled across multiple purchases rather than one line item, that ceiling is well above anything Mahjong Soul currently offers to buy in one sitting.
If you can shrug at cosmetics you’ll never own, this axis doesn’t matter much either way. If the gacha loop tends to hook you, Riichi City’s friendlier free drip is the safer platform to be on — just don’t assume its top-line prices are automatically the smaller of the two.
Rank systems
The two ladders are built on different philosophies. Mahjong Soul splits players into six tiers, Novice through the top rank of Celestial, with four-player and three-player results tracked on separate ladders. The general consensus, worth taking seriously, is that it’s noticeably softer than Tenhou’s competitive benchmark — results accumulate over many games, so raw skill matters less than simply putting in the reps. Even a bad stretch won’t stall your climb as long as you keep playing.
Riichi City’s ladder leans toward the harder, Tenhou-style model instead. The standout rule: coming in third counts against you almost as much as an outright loss, not as a safe middle finish. There’s no drifting up the ranks by just staying out of last place — you have to actually play to win each hand. The climb is tougher for it, but that pressure arguably builds better habits than a system that only asks you to survive.
For a beginner, Mahjong Soul’s forgiving ladder means you can lose constantly while learning the rules and still feel like you’re making progress. For a player who wants their rank to mean something more exacting from the start, Riichi City’s punish-third philosophy is the better training ground.
English support
Both platforms clear the bar that actually matters for this comparison: neither asks you to fight the interface the way Tenhou does. Mahjong Soul’s English localization is native-quality rather than machine-translated, and it’s a big enough part of the platform’s identity that it’s the standard answer to “where do English speakers play riichi online.” Riichi City’s English support is equally complete, shipping alongside Japanese, Korean, and Chinese rather than treating English as an afterthought bolted onto a Japanese-first client.
The practical difference isn’t in the quality of the translation on either side; both read naturally. It’s in what surrounds the translation, which is where the community gap covered below actually shows up.
Community, content, and longevity
Mahjong Soul has the longer track record of the two, and its 2026 event lineup reflects that: an April tie-in with Sword Art Online, a follow-up Akagi collaboration in June, and celebrations marking seven years since the English version launched. Landing a franchise crossover on the scale of Sword Art Online isn’t something a struggling operator manages, so it’s a decent signal the platform will still be running well past your first year of learning the game. That track record has also left behind a real community: streamers, YouTube tutorials, strategy threads, and enough accumulated English-language discussion that most beginner questions already have a written answer somewhere.
Riichi City is the newer of the two, but the numbers say it’s far from a niche side project: its official account confirmed passing 3.3 million total downloads back in February 2025. Its English-speaking community exists and is growing, and Steam reviews filtered to English are notably warmer than the aggregate “Mixed” rating, but it hasn’t reached the same critical mass of English-language third-party content as Mahjong Soul. That’s a natural consequence of having the smaller of the two English-speaking player bases, not evidence that the platform itself is thin. If part of what you want from a platform is a deep well of English guides and community discussion to lean on when you’re stuck, that currently favors Mahjong Soul.
Verdict: which should you actually install?
If you’re weighing player pool against teaching quality, that’s really the whole decision. Everything else — monetization ceilings, rank philosophy, event calendar — is real but secondary, and mostly cuts in favor of whichever platform you already leaned toward on the first axis.
Never played riichi before and want to be taught → Riichi City. Its lesson system is the best structured in-app instruction currently available between the two, and its gacha economy won’t punish you for not spending. Accept the smaller pool as the price.
Want to jump into games and find opponents fast → Mahjong Soul. The biggest English-speaking crowd of any riichi platform means quick matches at your level from day one, even though its tutorial has real gaps around furiten and the yaku requirement, gaps you can close in ten minutes with our beginner’s guide to riichi mahjong.
Genuinely can’t decide? Both are free and both let you play a real ranked game inside your first ten minutes, so don’t agonize over it: install both tonight, play a session on each before you sleep on it, and let your own first impression settle the question your reading couldn’t. For the deeper, standalone dives into each platform’s gacha math, rank ladder, and who it’s really for, see our full Mahjong Soul review and Riichi City review.
