About Rivaldle

Rivaldle is a free, browser-based daily guessing game built around the cast of Marvel Rivals. Every day a different character becomes the answer, and players have unlimited attempts to identify them across five distinct game modes. We built Rivaldle for the people who already love the roster — the players who can name a hero from a single ultimate splash, a torn silhouette, or four emojis pinned to the bottom of a Discord message.

Who is behind Rivaldle?

Rivaldle is an independent fan project, started in 2025 as a way to combine the kind of programming work we already enjoyed with a game we were already playing every night. We are not a studio and we are not affiliated with NetEase, Marvel Games, or Disney. The site is hand-built: vanilla HTML, vanilla CSS, an Express backend, and one shared Google App Engine deploy. There is no ad-tech behind the curtain other than what you can see in the page source. There is no analytics dashboard reading your inputs. We made the entire thing because we wanted to play it ourselves.

If you have built a Wordle clone before, you already know roughly how Rivaldle works under the hood. The interesting part — the part we have spent most of our time on — is everything that surrounds the puzzle: five different framings of the same daily answer, a streak system that rewards consistency rather than speed, a localization layer that runs in five languages, and a content set that we manually maintain as the Marvel Rivals roster grows. That last point matters more than it sounds. Each new hero added to the game requires us to research, transcribe, normalize, and translate roughly forty fields of data. We do that work ourselves, by hand, because that is the part of the game that we believe should never be wrong.

Why a daily Marvel Rivals game?

The original spark for Rivaldle was the realization that Marvel Rivals was missing the kind of companion puzzle that other competitive games have grown alongside them. League of Legends has LoLdle. Smash Bros. has Smashdle. Even niche fighters have community-run guessing games. The Marvel Rivals roster is genuinely well-suited to this format: heroes have distinct silhouettes, ability names that are themselves a kind of trivia, and visual designs lifted from decades of Marvel comics and films. The audience for this game is also broader than the audience for any one comic run. Someone who has only ever seen the MCU films can play a round of Emoji Mode and have a real chance. Someone who has been reading Hickman runs since 2012 will recognize a silhouette that confuses everyone else. We wanted a puzzle that worked at every level of fandom, and we wanted it to reset once a day so it stayed a conversation rather than a grind.

Resetting once a day is a deliberate constraint. Rivaldle does not let you replay a mode you have already cleared, and the answer is the same for every player on Earth on any given day. The reason is simple: the game is more interesting when it is shared. The fun of asking a friend whether they got today's emoji puzzle is gone if everyone is on a different randomized seed. The streak system reflects the same idea — it tracks consecutive days, not consecutive solves, because we want the game to be a habit rather than a high score.

How Rivaldle is built

Rivaldle is a static frontend with a small Express backend that serves the daily answers and the character database. There is no user account system, and we do not store anything about you on the server. Your streak and progress live entirely in your browser's local storage. If you clear your cookies, your streak is gone, and there is no way for us to bring it back — that is by design. We did not want to build a game that asked for an email address before letting you guess Wolverine.

The character database is hand-maintained in a single JavaScript file. Each entry contains the hero's role, HP value, gender, species, affiliation, eye color, hair color, year of first appearance in Marvel comics, an emoji string we authored, and the ordered ability list as it appears in Marvel Rivals. Every field is duplicated across five languages — English, Spanish, French, German, and Mandarin — because we wanted the puzzle to work for the international audience that Marvel Rivals already has. When a new hero is added to the live game, we add the entry, verify it against the in-game ability descriptions, and push the data set live the same week.

The five game modes share that single character database. Classic Mode runs a comparison grid, similar to other guessing games, where each guess is compared against the secret hero across eight categories. Silhouette Mode pulls the character splash, blacks it out, and reveals it gradually as you guess. Emoji Mode displays four emojis we picked to gesture at the answer without naming them. Character Ability Mode shows the literal text of one of the hero's abilities and asks you to identify the hero from the ability alone. Pixelation Mode, the newest mode, displays the character splash at extreme pixelation and unblurs it with each wrong guess. The shared database means the puzzles stay coherent across modes — if a character is in one, they are in all of them.

What we will not do

It feels worth being explicit about a few things, because the line between a fan project and a content farm is thinner than people assume. We will not sell or rent your data. We will not ask you to make an account. We will not paywall any mode. We will not run pop-ups or interstitial video ads. Rivaldle currently runs display advertising through Google AdSense and Ezoic in order to cover hosting costs; that is the entire business model, and you can read the details in our Privacy Policy. We will never charge for access, and we will never put a daily answer behind a subscription.

We also will not claim ownership over Marvel content. Every character on this site, every name, every ability, every visual is the intellectual property of Marvel Entertainment and its parent company, The Walt Disney Company. Rivaldle is an unofficial fan project that uses these elements under the doctrine of fair use for the purposes of commentary and transformative gameplay. If a representative of Marvel or Disney ever asks us to remove content, we will remove it. The disclaimer in the footer is not a formality. It is the basis on which this entire site exists.

Who Rivaldle is for

Rivaldle is for the player who has the daily Wordle bookmarked, who plays a few rounds of LoLdle while waiting for queue, who screenshots a Smashdle solve to a group chat. It is for the Marvel Rivals player who wants something to do during a queue pop, and for the comics reader who never installed Marvel Rivals but recognizes Adam Warlock from the cover of Strange Tales #178. It is for anyone who wants a small, daily, low-stakes puzzle that costs nothing and respects their time. We hope you enjoy it. If you don't, the close tab is right there and we will not chase you with an email.

Contact

Bug reports, feature requests, character corrections, takedown notices, and general feedback can all be sent to rivaldleguesser@gmail.com. We read every email and we respond to most of them. If you found a factual error in a character entry — wrong HP, wrong year of origin, an ability that does not match the in-game text — please include the character name and the field in your subject line. That is the fastest way to get the fix shipped.

You can also follow Rivaldle on Instagram, where we post roster updates, mode launches, and occasional notes about the puzzle of the day.
