XXXtreme Lightning Roulette keeps a single-zero roulette wheel but expands the multiplier sequence. The first Lightning phase selects numbers, Chain Lightning can add further qualifying spots, and Double Strikes can increase multipliers already attached to them. A straight-up wager on the winning qualifying number is required for its multiplied settlement; a red or black bet covering that number does not receive the same reward. Its bonus structure therefore needs its own payout table instead of instructions copied from standard roulette.
