Send a support request
Use the Feedback control on this page or inside the game. Choose the category that best matches the problem and include the screen, action, device, browser, and approximate time. The alpha does not yet promise a response-time service level.
Do not include a recovery key, session token, passkey export, device PIN, biometric information, or administrator credential.
Account and recovery
Play without an account
Guest play works immediately. Guest identity is linked to local browser data, so clearing site data or changing browsers can remove access to guest progress.
Protect or restore a player
Open Player Identity from the avatar control or visit the account page. Choose Protect this player to create a passkey. Store the one-time recovery key somewhere private. If the passkey is unavailable, choose Use recovery key and register a new passkey on the current device.
Delete a protected account
Open Player Identity, expand Account controls, type DELETE, and confirm with your passkey. Deletion is permanent and removes the supported account identity and related game records described in the Privacy Policy.
Browser and connection help
- Use a current version of Chrome, Edge, Firefox, or Safari where WebAssembly and WebGL are enabled.
- Reload once after a deployment if the loading screen does not advance.
- Check that content blockers are not preventing requests to gostop.io or api.gostop.io.
- For missing sound, interact with the page once and confirm the tab and game audio settings are not muted.
- For a disconnected multiplayer match, leave the tab open briefly so automatic recovery can run before starting a new room.
- On a slower device, enable Low performance mode and reduce browser tabs running in the background.
Gameplay questions
The guided first match and table coach explain legal plays, matching, captures, and Go or Stop decisions. For a rules disagreement, report the cards involved, the turn stage, the action taken, and the result shown. A screenshot is useful, but do not include private browser or account screens.
Progression and achievement changes are confirmed by the backend. If rewards appear delayed, reopen the Profile after the match settles before replaying the same action.
A useful bug report
Include these details when practical:
- What you expected and what happened instead.
- Whether the match was practice, guided, or multiplayer.
- The browser and device type, screen orientation, and Low performance or reduced-motion setting.
- The last visible turn message and whether reloading changed the result.
- The approximate local time and the public version shown in the page footer.
Feedback may include technical context such as the route, platform, version, and build identifier automatically.
Security and abuse
Use Feedback with category "Bug or broken behavior" and begin the message with "Security report." Describe the affected surface and impact without publishing exploit instructions or accessing other players' data. For immediate account safety, sign out, secure the device, and use the recovery flow to replace an unavailable passkey.
Privacy requests
For access, correction, deletion, or another privacy request, use Feedback with category "Something else" and begin the message with "Privacy request." Include the player display name and enough non-secret context to locate the profile. See the Privacy Policy for data categories and retention.
