Open browser alpha · Five-minute test
Help us make the ice clearer.
Try a River section, practise on Mirror Pond, or play an online match with another person. Tell us the first moment you were unsure what would happen, what you expected, and which device/browser you used.
Playing is free. You can play anonymously and use the Feedback button at any time. To track your playtest and get private replies, use a free game account and opt into this program. This is not an invitation to share identifying details or permit research use of replays.
Generative AI assistance was used for programming code and written text. Game artwork is not AI-generated, and computer opponents use the game's own policies.
Checking account availability…
Sign in or create a game account to join the tracked playtest. Return to this page after signing in. Accounts must meet the site's age rules; guests can still play and report anonymously.
1. Join the tracked playtest
2. Try a five-minute task
Start at Home, choose Solo river journey, or find another person online for a lake match. Computer practice is available if you want to learn the rules first. You do not need to finish to give useful feedback.
3. Report what happened
Submit a separate account-linked report each time you actually playtest. A second report helps distinguish a returning tester from a one-time applicant. These are self-reported sessions, not automatic gameplay surveillance.
My playtest record
Replies appear here or in Feedback → My tickets when you return. Game accounts do not require an email address, so this page does not send email reminders.
Owner: tracked playtest roster
Available only to the bound owner after recent authenticator verification. Distinct signed-in account IDs, self-reported sessions, and ticket review states—not unique website visitors. Anonymous feedback remains separate.
