How do credits work?
Each solve uses a set number of credit(s) from your balance. Failed solves are refunded automatically. New accounts start with 20 starter credits. Your starter credits never expire, and neither do credits you claim or earn. Every change is listed under Credits. Credits have no cash value.
How do I get more credits?
Claim your free weekly credits on the Overview tab once every 7 days, or invite friends. The admin can also add credits.
How do referrals work?
Share your link from Invite friends. It only works for people who don't have an account yet, and the admin still lets each new person in. You both get the bonus after your friend's first solve. Each account can refer a limited number of friends (shown on the Invite friends tab).
How do I connect the extension?
Open the SparxSolver extension and press Connect account, then sign in here with the same Google account. Linked browsers are listed under Security.
I think someone else is using my account
Go to Security and press Sign out everywhere. That ends every session and disconnects every extension. Then sign in again.
Still stuck?
Ask the admin who let you in. Include the time it happened and your user id: —.
