Lightning Roulette is a European roulette variant with a 37-number wheel (0-36).
Place bets on individual numbers, red/black, odd/even, dozens, columns, and more.
Each round, 1-5 random lightning numbers are struck with multipliers (50x-500x).
If your straight-up bet hits a lightning number, you win with the enhanced multiplier.
Standard straight-up bets pay 29:1 (reduced from 35:1 to fund the lightning multipliers).
Outside bets (red/black, odd/even, etc.) pay at standard rates.

The lightning multiplier mechanic adds significant variance to standard roulette. While outside bets maintain normal probabilities, straight-up bets have a 1/37 chance of hitting, with a further ~8% chance of that number being a lightning number. The reduced 29:1 base payout funds the multiplier pool.
