Your practice, on your device.

Last updated October 4, 2026

Local game progress

We store unfinished rounds, submitted practice answers, recently seen question IDs and up to 20 completed rounds in your browser's local storage. This lets you continue a round and see local scores. The game does not upload these records to a game server or official Krillion account.

Use Clear progress in the game to remove its saved record. You can also delete this site's storage in your browser settings. Private browsing or storage restrictions may prevent saving.

Hosting and requests

Our hosting provider, Cloudflare, receives ordinary web requests, including IP address and browser request information, to deliver and protect this site. See Cloudflare's privacy policy. Fonts and game images are served with the site.

Private friend challenges

When you create or join a challenge, the game server receives your nickname, submitted answers and answer times. These are stored with a private room code in Cloudflare Durable Objects so two players can see shared progress. Opponent answers are shown only after the match. Use a nickname rather than a real name and do not type sensitive information.

Rooms stop accepting requests one hour after creation and active room storage is deleted through a scheduled storage alarm. Cloudflare may retain recovery copies under its storage retention system. A private reconnection token is stored in this browser until you leave the room or clear site data. Rooms are not public profiles or a global leaderboard.

Advertising and analytics

This release contains no advertising scripts, third-party analytics tags or account system. If that changes, this page and the relevant controls will be updated before those services are enabled.

Sharing and email

Sharing a result is optional. Only the result text you choose to share is passed to your device's share function or clipboard. If you email support, your message and address are processed by our email providers so we can reply.

Do not include sensitive personal information in game answers or correspondence. We do not request your real name, date of birth or payment details.
