VectorSpace

Play the published collection

Twenty browser games in one portable folder, with online rooms for up to eight friends. No sign-in, ads, remote fonts, or build step. The bundled PeerJS library connects players directly.

Play locally

Use Download for offline play on the site, extract the entire ZIP, and open VectorSpace/index.html. It includes 17 games for solo or same-device play, including 12 games with computer opponents. No installation, API keys, or internet connection is needed for those modes. Imposter, Mafia, and Sketch Party require online friends. Spectrum can be played locally by passing the device. The Vs computer and Offline & local filters make each mode easy to find.

For development, open game-night/index.html. Run node tools/build-offline.cjs to rebuild the downloadable ZIP after editing browser assets. The Pages workflow rebuilds it before every deployment.

Play with friends

Choose Create a room, enter your name, and send the six-character code to friends. They open the same site, choose Join a room, and enter the code. The host selects a game; guests press Ready, then the host starts. Every game has an online mode, including cooperative Team Solitaire. Player limits are shown on each game.

The host’s tab runs the room and must stay open. Private hands, words, identities, and roles are sent only to the corresponding player, although the host’s browser necessarily holds the complete state. This is designed for trusted friends. Refreshing or closing the host ends the room; brief guest disconnections can rejoin the same seat. There is no permanent account or match history.

Online play uses PeerJS’s free public signaling service and WebRTC. Some school, work, mobile, and restrictive router networks block signaling or direct connections. A website’s content or metadata cannot guarantee a web-filter category or access through a school’s policy.

For local development, run node tools/serve.cjs and visit http://127.0.0.1:4173/.

Face Finder — Guess Who-style deduction with 24 original illustrated characters, against the computer offline or a friend online.
Mafia — 4–8 players, private roles, night actions, investigation, protection, discussion and voting.
Liar’s Dice — hidden dice, escalating bids, challenges and elimination; offline CPU or online friends.

Each game includes its rules and any house variants. These are independent implementations with original presentation, not official versions or affiliations. Imposter, Mafia, and Sketch Party require online friends. CPU strategies use only their own player views; they cannot read your hidden identity, dice, or next choice. Solo games reset when leaving; online rooms stay connected while browsing the library. Motion respects reduced-motion preferences, and optional sound is off by default.

Verify the games

Install jsdom@30.1.0 as a development tool, then run node tools/check-games.cjs. You can also pass an absolute path to an existing jsdom package as its argument. It checks the original games’ start screens, complete computer games, fleet placement, legal dice combinations, local memory play, private party-game state, and timer cancellation. Run node tools/check-rooms.cjs, node tools/check-social.cjs, and node tools/check-competitive.cjs for transport and online engine checks. Run node tools/check-cpu.cjs (with the same optional jsdom path) to verify CPU strategies, complete matches, offline controls, and timer cleanup. Run node tools/check-download.cjs with the optional jsdom path to extract and test the actual ZIP with all external network access blocked. The published games need no package installation.
