This is a free social casino. The games are played with virtual coins only — there is no real-money betting, no deposits and no prizes. Entry is still limited to adults aged 18 and over.
By continuing you confirm your age. We keep that confirmation in your own browser storage and nowhere else.
Registration keeps your nickname and coin balance on this device. Your email and password are hashed with SHA-256 in the browser — nothing is sent anywhere and no server ever sees them.
Clearing your browser data removes the account and the coin balance for good. There is no recovery, because there is nothing stored on our side.
