Web roguelikes with no pay-to-win, and how to tell a real one from a monetised one
Traditional roguelikes are the least monetised genre in games, and one of them has been playable in a browser tab for years. Here is what to play and the four checks that expose a free-to-play trap.
- Topic
- Open source
- Difficulty
- beginner
- Spoilers
- None
The word “roguelike” has drifted far enough that it now covers two almost unrelated things. The original meaning — turn-based, grid-based, procedurally generated, permadeath, no meta-progression — describes a genre that has been free and open source since the 1980s. The modern meaning covers action games with random levels and a permanent upgrade tree, and that version is where the monetisation lives.
This is about the first kind, which is the kind that is genuinely free and genuinely has no pay-to-win, because there is nothing to pay for.
Dungeon Crawl Stone Soup — playable in a browser right now
Dungeon Crawl Stone Soup is one of the major traditional roguelikes, and it has the best browser story in the genre. WebTiles is an official tile-based interface that runs in a browser tab against a public server.
- What it is: a full traditional roguelike — turn-based, grid-based, deep, unforgiving
- Where: a list of community servers at crawl.develz.org/play.htm, including crawl.akrasiac.org, cbro.berotato.org and crawl.dcss.io
- Cost: nothing, and there is nothing to buy
What makes WebTiles the standout is not the graphics, it is what the server model gives you:
- Saves live server-side. Close the tab, come back tomorrow, continue. No save file to lose.
- Spectating. You can watch other players’ runs live, which is the single fastest way to learn the game.
- Chat and ghosts. The community is built into the interface.
- It works on anything with a browser. The heavy lifting happens on the server, so a decade-old laptop plays it identically to a new one.
Crawl is the recommendation if you want one traditional roguelike and you want it in a browser with no setup at all. Expect to die a great many times. That is the genre, not a difficulty setting.
Shattered Pixel Dungeon — excellent, but not a web game
Shattered Pixel Dungeon is a traditional roguelike dungeon crawler based on Watabou’s Pixel Dungeon source, developed by Evan Debenham. It is a superb game and one of the best open-source games of the last decade.
- Licence: GPL-3.0
- Built with: libGDX (Java)
- Official platforms: Android, iOS and desktop
The correction you will not find in most recommendations: there is no official browser version. The project’s official builds are the mobile and desktop ones. If you have seen a “Shattered Pixel Dungeon web version”, it is a third-party port — several exist on GitHub, and community projects like Pixel Crawlers have built browser-native versions. They are unofficial, they lag the upstream releases, and the developer does not support them.
That does not make them illegitimate — the GPL-3.0 licence explicitly permits forks and ports, which is the whole point of it. But if you want the actual current game, install the real build. If you want to play in a browser, understand that you are playing somebody’s port of a version that may be months old.
Cataclysm: Dark Days Ahead — the other free one
Cataclysm-DDA is a turn-based survival roguelike with a level of simulation detail nothing commercial matches. Vehicle construction, crafting trees, mutations, a world that generates its own history.
- Licence: Creative Commons Attribution-ShareAlike 3.0
- Built by: over a thousand volunteers
- Cost: nothing
It is not a browser game and it is not beginner-friendly — the interface is a keyboard-driven menu system with a cliff for a learning curve. But it belongs in this list because it is completely free with no monetisation of any kind, and because it demonstrates how far a volunteer project can go.
The four checks
Most “free” browser roguelikes are not. These four questions separate them in about a minute.
1. Is there a currency? Gems, coins, energy, keys, crystals — if the game has one, it has something to sell. A traditional roguelike has no economy outside the game world, because the run is the whole game.
2. Is there a timer or an energy bar? “You have 5 lives, next in 20 minutes” is the signature of a game designed around interruption. Traditional roguelikes are turn-based, which means they wait for you indefinitely, on purpose.
3. Can you buy an advantage? Even a cosmetic-only shop is fine. The problem is anything that affects a run: extra lives, starting items, stat boosts, continues. In a genre whose entire identity is permadeath, paying to undo death removes the game.
4. Is the source available, or is the server the product? If the source is open, nobody can secretly monetise you — you can read the code. If it is closed and browser-based, the server controls everything, and the interface you are looking at can change under you next week.
What we would actually play
| Game | In a browser? | Licence | Cost |
|---|---|---|---|
| Dungeon Crawl Stone Soup | Yes, WebTiles | Open source | Free |
| Shattered Pixel Dungeon | No — unofficial ports only | GPL-3.0 | Free |
| Cataclysm: Dark Days Ahead | No | CC BY-SA 3.0 | Free |
Start with Crawl in a browser tab. It costs nothing, requires no install, and if you bounce off it you have lost twenty minutes rather than an afternoon.
And if you want something you can play immediately without any of this setup, we host a handful of small browser games — different genre, same principle: nothing to install, nothing to buy, source readable.
