Seven Down

Roll a die across a board without ever seeing the face that matters. Opposite sides of a die always add up to seven, so the number underneath is the one you keep in your head. Three games share that rule: 60 puzzle boards with one roll per press and a par to beat, 120 chased action stages across six biomes, and 60 mazes in the dark, drawn only where you have already been. A new daily puzzle every day, twelve awards, playable offline, nothing to sign up for.

Plain HTML and JavaScript with three.js vendored in: no build step, no dependencies, and the whole game zips to about 230KB. Textures, audio and boards are generated at runtime, and every level is proved solvable by a solver before it ships. Each portal gets a thin wrapper around the same source for its SDK, ads and leaderboards. It is live on CrazyGames and Playgama, with more portals to follow.

iOS and Android are Capacitor wrappers around the same build, with Game Center and Play Games leaderboards wired in. Both run on real phones and are on their way to the App Store and Google Play.
