Seizer

Seizer is a free way to play the board game Carcassonne online. It runs in your browser with no download and no required account, and there are also iOS and Android apps. It's the most optimized mobile Carcassonne experience.

You can play live games with friends or random opponents, quick games against bots, or async daily games where each player takes their turn whenever they have time, like correspondence chess. Games can be shared with a simple invite link, so it works well for groups that can never get together at the same table. Most matches take 10 to 15 minutes.

Several expansions are included free: The River, Tiles & Taverns with a big follower and high-risk tiles, and a strategy variant where you hold up to 3 tiles in hand, with more added regularly.

Compared to Board Game Arena or the official Carcassonne app, Seizer is lighter: free, no subscription, cross-platform, and built for casual play on any device. Made and actively maintained by a solo developer, with updates shaped by player feedback.
