Skymo is a free card game you play in your browser with 2 to 8 players, in real time. Nothing to install to start a game. Skymo is also available as an iOS and Android app, with an interface built for the phone. No account unless you want one. A game lasts about ten minutes.
Skymo is built and run by Maxent Rouault, an independent developer based in France, under a registered one-person business. There is no team: the same person writes the code, draws the screens, reads the support form and answers on Discord. That is also why the game ships in French and English only, and why features arrive one at a time rather than in batches.
Skymo started as a way to keep a card game going with friends who had moved away. Playing it online meant everyone installing the same app, making an account, and landing in a lobby covered in banners, so it was built the other way round: you send a link, your friends type a code, and the game starts. The app comes after, for the people who play often enough to want Skymo on their home screen. Enough people kept turning up that a weekend fix became something maintained. The rules are adjustable because every table plays a little differently, some clearing rows as well as columns, and a player who loses connection can rejoin the round in progress, because a dropped connection should not end the evening.
Skymo carries no advertising and never will. Playing is free, with no paywall in front of a match and no energy bar counting your turns. Whatever may be sold alongside it will never touch how a game plays: an advantage over other players is the one thing that will never be for sale. An account is optional and exists only so your stats, your friends and your games follow you from your phone to your laptop.
Bugs, ideas and complaints are all welcome. The support form is the fastest route, and the Discord server is where new versions are announced first.
