Quiz rules

Each quiz shows its entry fee, duration, attempt limit, passing score and reward before you start.
The entry fee is deducted from your wallet when the attempt starts.
The timer runs server-side; if it expires your attempt is submitted automatically with the answers saved so far.
Answers are saved as you go, so a lost connection does not lose your progress.
An attempt can be submitted only once. Duplicate submissions are ignored.
Rewards are credited only if you meet the passing score.
Leaderboard ranking uses total score, with faster completion breaking ties.
Any form of cheating or automation results in disqualification and possible account suspension.
