# Attempts & rewards
***
QRBase manages attempts and rewards at the level system layer — not just at the individual puzzle level. This structure keeps the economy healthy, rewards real skill, and reduces low-quality farming or automated abuse.
### Daily free attempts
Every player receives **free attempts per day** based on their current level. Free attempts **reset at UTC midnight**.
### Buying extra attempts
Each extra attempt is priced in $SCAN based on your current level — the higher your level, the higher the cost. Payment is verified on-chain via ERC-20 transfer to the QRBase treasury on Base.
### Earning extra attempts
* **Tasks** — complete a task bundle to earn +1 attempt.
* **Referrals** — refer a friend who buys an attempt to trigger a referral reward.
***
### **Daily Limits**
Daily limits exist to protect the reward economy and discourage repetitive farming. Depending on your current level, the system applies:
* different free attempt counts
* different daily caps
* shorter puzzle timers
* more difficult shuffle configurations
Lower levels are designed to be more forgiving and accessible for new players. As players progress, rewards become significantly larger, entry costs increase, timers get shorter, and daily limits become stricter — creating higher-risk, higher-reward gameplay for skilled players.
### Win reward
Prizes are paid automatically on-chain the moment a puzzle is solved and scale with your level — higher levels, bigger payouts. A wallet address is required to receive the payout. Wins are still recorded even if no wallet is connected, but the payout is skipped.
#### **Fair Play and Anti-Cheat**
QRBase uses anti-cheat systems and bot protection to keep rewards fair and sustainable. Protection measures may include:
* suspicious activity monitoring
* advanced solve validation
* reward blocking for flagged accounts
* detection of repeated farming patterns
Successfully solving a puzzle does not automatically guarantee a payout. Rewards can still be blocked if an account fails fair-play checks.

**Eligibility note:** Farcaster eligibility is more open than before, but QRBase still protects the platform using stronger solve validation and anti-farming systems.
