3 imagesSolitease
A browser version of the Danish card game drille-kabale, “tease solitaire”. Two or more players race to empty their own pile onto shared foundations, while they sabotage each other by stacking cards onto the other piles. Multiplayer is peer-to-peer over WebRTC, and practice mode plays against bots, also offline.
3 images30
A push-your-luck dice game for two or more players. Everyone starts with 30 lives, and the last player alive wins. Play on one device with friends or bots, or on a device each over a peer-to-peer connection, joined with a room code or a QR code. A score keeper tracks the lives when you play with real dice.

$ORIGINand$TTL, and turns TTLs such as1hinto seconds, so only real changes show up. Unified or split view, and it all runs in your browser.
2 imagesSecret Santa
My family draws names every Christmas, so each of us buys one gift instead of many. This tool does the draw: add the names and get one link per person. Each link reveals only who that person gives a gift to. The pairing is stored in the link itself, so there is no server and no sign-up.
