Voluntary support

Your attention funds the room.

Watch a short rewarded video when you choose. A verified completion adds 0.2 credit to your ledger. Credits never expire, and you can always use free practice without watching anything.

Server verified

Credits are granted only after a trusted event is accepted by the API.

No expiry

Your earned balance does not disappear at the end of the month.

Clear limits

A visible daily cap protects the experience from abuse.

In production, this page is connected to a rewarded web provider with a signed server-to-server postback. Client-side completion events alone never create meaningful credits.
