Quick troubleshooting
The game does not load
Refresh the page, confirm JavaScript and site storage are enabled, disable extensions that block required game files, and try a current version of Chrome, Edge, Firefox, or Safari. If the problem continues, include your browser, device, game, route, and what appeared on screen.
My progress disappeared
Most progress begins in browser local storage. Clearing site data, using private browsing, switching browser profiles, or changing devices can remove it. BernStone Stacks supports profile export and import where available. Account-bound purchases can be restored after signing into the same supported account.
A score or daily result did not submit
Check your connection and public player name. Security limits may reject impossible, malformed, duplicate, or excessively frequent submissions. Send the game, mode, approximate time, player name, and screenshot if you believe a valid run was rejected.
Purchases and refunds
Checkout is handled by Stripe. For a missing entitlement, sign into the account used at checkout and retain the Stripe receipt or checkout session reference. Never email full card details.
See the Refund Policy before submitting a request. Refunded or reversed purchases lose the associated digital entitlement.
Advertising and rewarded lives
Passive banners are limited to non-live surfaces such as menus, results, and the Cosmetic Forge. Rewarded inventory is optional and grants the displayed reward only after the provider confirms completion. Ads can be unavailable because of region, consent, connectivity, inventory, account configuration, or ad-blocking software.
