10 Games Like Hearthstone (Browser Card Battlers)

Hearthstone runs in the browser — Blizzard ships an official web client — but most players want alternatives, whether for variety, for a lighter install footprint, or to play on hardware where the official client struggles. These ten games like Hearthstone cover the CCG and deck-builder space in browser, from PvP card duels to single-player roguelite deck-builders to the indie scene’s wildest experiments. All are free in Chrome with no download.

1. Eternal Card Game

The most direct Hearthstone competitor still in active development. Eternal Card Game offers the same one-versus-one turn-based card duel structure with five factions, a deep constructed format, and competitive draft modes. The pace is faster than Magic and the rules cleaner than Hearthstone’s tempo-driven meta. Browser version available via the developer’s web client.

2. Faeria

A card game with a hex-grid board on which units physically move. The grid mechanic gives Faeria a tactical layer Hearthstone never had — positioning matters, terrain matters, and a card’s value depends on where it can reach next turn. The game went free-to-play and open-source in 2020. Multiple browser ports exist.

3. Slay the Spire (Web Version)

Not multiplayer, not a CCG — but Slay the Spire is the modern standard for single-player card-game design and a fan-made browser port has existed for years. You climb a procedural dungeon, building a deck from the cards each fight rewards. The skill ceiling is enormous, the runs are tight, and the deck-building feedback is faster than anything else on this list.

4. Card Crawl

A dungeon-crawl roguelite played on a four-card grid. Each turn you draw and play from a small hand, fighting through a deck of monsters. Card Crawl turns the CCG vocabulary inside out — there’s no opponent deck, just a procedural enemy stream — but the satisfaction of finding the right play with limited options is straight from the CCG playbook. Mobile-first design that ports cleanly to browser.

5. Monster Train (Browser Demo)

The deck-builder roguelite that took the Slay the Spire formula and added a three-tier battlefield. The full game is on Steam, but the official browser demo covers the first run and gives a clean intro to the core deck-building loop. The mechanic of choosing where to deploy each unit across three floors is genuinely novel.

6. Cards of Cthulhu

An indie browser card game in the Lovecraftian horror vein. You play as an investigator deck-building against escalating supernatural threats. Smaller scope than the genre giants, but the theme is committed and the mechanics borrow from both classic CCGs and modern roguelite deck-builders.

7. Yu-Gi-Oh! Master Duel (Browser via Steam Cloud)

Master Duel is a free-to-play Yu-Gi-Oh! client from Konami. The native client is the main version, but Steam Cloud and similar services can stream it to a browser tab. If you grew up with Yu-Gi-Oh!, the modern competitive client is the closest to a true CCG-grade Hearthstone alternative — deep card pool, an active meta, and frequent format rotations.

8. Magic: The Gathering Arena (Browser via WebGL Wrapper)

Wizards’ free-to-play MTG client has no official browser version, but the company has experimented with web-launchable previews. The full game is desktop-native; for full browser play, see Magic Online’s older clients or fan-made browser sims. Worth a slot here because no list of CCGs is complete without Magic.

9. Hand of the Gods (Discontinued — Spiritual Heirs)

Hi-Rez’s CCG died, but the genre’s interest in grid-positioning card games persists in indie titles like Tactical Spear, Cards of Cthulhu, and other small-team experiments listed across the browser indie scene. If you specifically want a grid-tactics CCG and Faeria isn’t enough, the indie space has more than you’d expect.

10. Solitica (and Other Solitaire-Likes)

Wider net: solitaire-derived single-player card games like Solitica, Pirate Cards, and the deeper indie titles in the Zachtronics catalog. None of them are CCGs in the Hearthstone sense, but they share the satisfaction of playing the right card at the right moment. Best for players who came to Hearthstone for the puzzles, not the PvP.

What about Hearthstone itself?

For completeness: Blizzard’s official Hearthstone web client lets you play directly in a browser tab after logging in with a Battle.net account. It’s the best way to play Hearthstone if you’re on a Chromebook or any machine where you can’t or won’t install the native app. Performance is roughly equivalent to the native client. The reason it doesn’t headline this list is that you came looking for alternatives — but worth knowing the option exists. The Hearthstone Wikipedia entry covers the game’s history if you want the long version.

CCG vs deck-builder roguelite

The genre Hearthstone helped define has split, in 2026, into two distinct camps. Traditional CCGs (Hearthstone, Eternal, MTG Arena) charge real money for card packs and rely on competitive PvP to keep players engaged. Roguelite deck-builders (Slay the Spire, Monster Train, Inscryption) are one-and-done premium games where you build temporary decks within a single run. Browser-wise, the roguelite camp is much better represented — the long-tail player base for free single-player card games is huge. For more of those, see our browser deckbuilder roundup.

Mobile playability

Hand-based card games suffer on narrow screens. Faeria, Card Crawl, and Slay the Spire’s mobile-aware versions handle it well. Eternal Card Game and the MTG-family clients want at least a tablet-sized screen. For phone-only sessions, stick with Card Crawl or the indie roguelites built for mobile from the start.

Frequently asked questions

Is Hearthstone playable in browser?

Yes — Blizzard runs an official browser client. You’ll need a Battle.net login. It supports the full game, including ranked play, arena, and constructed modes.

What is the closest free game to Hearthstone in browser?

Eternal Card Game is the most direct competitor with the same one-versus-one turn-based card-duel structure. Faeria is the closest if you want grid-positioning mixed in. For single-player, Slay the Spire’s web port is the genre standard.

Can I play Magic: The Gathering Arena in browser?

Not officially as a free standalone web client. The native MTG Arena client is the main supported version. Cloud-gaming services can stream it to a browser, but require a subscription and account linking.

Are roguelite deck-builders the same as CCGs?

They share the deck-building DNA but diverge sharply on monetization and structure. CCGs (Hearthstone, MTG, Yu-Gi-Oh!) build long-term collections through paid packs. Roguelites (Slay the Spire, Monster Train) give you a fresh temporary deck each run with no real-money progression.

Which of these are kid-friendly?

Card Crawl and Slay the Spire are mechanically rich but free of mature content. Eternal Card Game and Faeria are similarly safe. The Yu-Gi-Oh! and Cards of Cthulhu titles include some intense art and themes; check before sharing.

Pick your poison

If you want classic CCG against humans, Eternal is the starting point. For tactical card battling on a board, Faeria. For the genre’s best single-player experience, Slay the Spire. And when twenty-minute card matches are too much, the Chrome Dino game resets your brain in about thirty seconds at the top of this site.
