Keno is a high-variance lottery-style game. The probability of matching all 10 picks is approximately 1 in 8.9 million. However, matching 5-7 numbers happens frequently enough to keep sessions interesting. The paytable is weighted to favor the house heavily on lower matches while offering massive payouts on rare high matches.

🔒 For Casino Operators

Engine Mechanics: Random number generation picks 20 from 80 numbers. Payout table heavily favors house on low matches.

RTP Control: Target RTP is configurable via the Dashboard → Game Control tab. The engine uses dynamic payout adjustment: rtpFactor = targetRTP / currentRTP clamped to [0.1, 2.5], applied to every win. Over ~500 rounds, actual RTP converges to target within ±1%.

House Edge: 7.5% at default settings. Revenue per 1,000 rounds at €1 avg bet: ~€75.

Variance Profile: Highest house edge game in portfolio. High variance — 7+ matches are rare but pay big. Most profitable game per round for operators. Max exposure on 10/10 match is 50,000x but probability is ~1 in 8.9M.
