Huh. In roulette, the green spot is pretty brilliant as it’s the “reasonable” explanation for being the odd man out on of the bets (not in: thirds, half, color, parity, corner betting, etc), so it’s incorporation fixes all those bets so they can have the otherwise “expected payout”- some house edge, but it doesn’t solve the single number payout issue, so they have to lower the payout for that bet. As it’s so high it seems reasonable. Neat
