Marvel Snap turned card games into something you can finish on a bus ride: short matches, three lanes, and cards that flip face up one after another until someone blinks. We kept coming back to one part of that loop more than any other, the not-knowing, so we built Hidden Fronts, an original card game where the rival’s whole side of the board stays hidden until the final turn. It runs right here on this page. Free, no download, no signup, no account.

How to play
A match runs five turns across three fronts: Ridge, Bridge, and Reef. Your energy grows by one each turn, up to five, and every card in your hand costs energy to place. Tap a card to select it, then tap a front to commit it there. Your own cards stay visible the whole match, but the rival’s side only shows a hidden-card count until the fronts flip on the final turn. Whoever has more total power on a front wins it, and whoever wins more fronts wins the match. On that last turn you also get one Overcharge, a one-time move that doubles your power on a single front, so the last few taps carry real weight. Every day runs the same opening shuffle for everyone, so your wins, streak, and best fronts-won are worth comparing. All of that is saved on your device. Nothing leaves your browser.
How it compares to Marvel Snap
Hidden Fronts keeps the shape of Marvel Snap that hooked us: three lanes to win, a cost curve that forces real trade-offs, a short clock, and a big swingy button that doubles the stakes right when it matters most. We leaned harder into the hidden-information part of that loop than the original does. In Marvel Snap, both sides pick a card in secret each turn, then everything on the board becomes visible again once that turn resolves. We stretched that tension across the whole match instead: the rival’s board stays a mystery from turn one until the final flip, so you are planning against total uncertainty rather than a board you can see building up.
We also cut almost everything else. There is no collection to build, no season pass, no cosmetics, and no changing lane effects that shift the plan every game, since our three fronts always behave the same way. Our card pool is twelve original pieces we designed ourselves, not the hundreds of cards Marvel Snap has released since launch, and you are playing one AI rival with a readable strategy rather than another human. A match here takes a couple of minutes; Marvel Snap’s real matches usually run a bit longer once you account for deck strategy and lane reveals compounding across six turns.
When should you get the real thing? The moment you want deckbuilding, a real opponent, and lanes that change the plan every game. Second Dinner’s Marvel Snap is the full card game, built around a deep card pool, ranked ladders, and location variety no single web page can hold. Hidden Fronts is the two-minute fix when you just want the tension of a hidden board and a big final-turn decision.

Frequently asked questions
Can I play Marvel Snap in a browser?
Marvel Snap does not have an official browser version; it runs as a native app on phones and through a PC client. Hidden Fronts, the game on this page, is our own original card game built around the same three-fronts, energy-curve loop, and it runs in any modern browser on phone or desktop with no install.
Is this the real Marvel Snap?
No. Hidden Fronts is an original game we designed, inspired by Marvel Snap’s fast lane-battle format. It is not affiliated with, endorsed by, or connected to Second Dinner or Marvel in any way. Every card name, icon, and mechanic in our version is our own work, and the download links above point to the official game.
Why can't I see the rival's cards until the end?
That is the whole hook. We hide the rival’s side of the board for the entire match instead of revealing it turn by turn, so every card you place is a guess against the unknown. The final turn, when both boards flip and the fronts are scored, is where the tension pays off.
Is it free?
Completely. There are no ads, no in-app purchases, no accounts, and no data collection. Your wins, streak, and best fronts-won are stored in your browser’s local storage and never sent anywhere.
Does it work offline?
Once the page has finished loading, the game makes no further network requests, so a dropped connection will not interrupt a match. That makes Hidden Fronts a reliable pick when you want a quick card game without depending on a live connection.
