Casino Bonus Hunter

Scans 30+ online casinos, calculates the Expected Value of each welcome/reload/cashback bonus using optimal blackjack strategy, adjusts EV by casino reputation score, and outputs a ranked list so you know exactly which bonus to hunt next.

Ranks casino bonuses by adjusted Expected Value — EV calculated with optimal blackjack strategy (0.3% house edge), then multiplied by a reputation score (0-10) based on CasinoGuru ratings and payout history.

What it does

1. Evaluates 30+ welcome, reload, and cashback bonuses from crypto and traditional casinos
2. Calculates EV: bonus - (wagering * house_edge) with optimal strategy
3. Adjusts EV by reputation: a $400 EV bonus at a shady casino scores lower than a $300 EV bonus at BitStarz (9.2/10)
4. Outputs ranked JSON + console table

EV Formula

EV_gross = bonus_amount - (bonus * wagering_x / game_contribution * house_edge)
EV_adjusted = EV_gross * (reputation_score / 10)

Example — Stake $500 welcome (40x wagering, blackjack):

• Real wagering = $20,000
• Expected loss = $20,000 * 0.3% = $60
• EV_gross = $500 - $60 = +$440
• EV_adjusted = $440 * 9.1/10 = +$400 (accounts for Stake's reliability)

Output

Saves to /tmp/casino_bonuses.json with full details per bonus.

Strategy notes

• Always play blackjack for wagering (0.3% edge vs 4%+ for slots)
• Check game contribution — some casinos count blackjack at only 10%
• Cashback bonuses have wagering x1 = almost free money
• Filter by BONUS_MIN_REP=8 to avoid unreliable casinos
