A 3D physics dice roller for your browser. Throw up to 100 dice at once (d4–d100), watch them tumble and settle, read the total. Runs entirely on your device — no accounts, no tracking, no network.
Optional one-time unlocks add custom looks and extra modes — buy once, yours forever.
The full dice roller — every die type, physics throws, history, and a stack of earn-as-you-play extras (themes, sound packs, fairness check, odds preview). No account.
Small touches that make it yours — a one-time unlock, lifetime license, no subscription, works offline, activate on as many of your devices as you like. Pricing and checkout are coming soon.
Game modes and more are on the way.
Castahedron is free, and the free features stay free. The optional premium unlocks (custom skins, custom interface colours, extra game modes) are still in development and are not on sale yet — there is no checkout, and the extension has no key field to fill in. When they launch, keys will arrive by email, activate offline, and never expire. Nothing you install today will start asking you for money.
Premium unlocks are not yet on sale, so there is nothing to refund today. Once they are: because license keys are delivered instantly and work offline, we generally won't offer refunds once a key has been issued. If your key doesn't work or you were charged in error, email [email protected] within 14 days and we'll make it right (replacement key or refund). Refunds will be processed through Lemon Squeezy.
