When placing your bet, you should be aware that not all bet types will allow you to access the bonus rounds. All inside bets will allow you to trigger it. This includes all straight-up bets and split bets. However, outside bets (e.g. red/black, odd/even) will not allow you to trigger the bonus game.
It is worth noting that the multiplier awarded will be affected by the bet you made. If it was a straight-up bet, you will be awarded the full multiplier. Split bets will be halved, quarter bets will be divided by four, and line wagers will be awarded at ⅙ of the multiplier.
Mega Fire Blaze Roulette offers the biggest and best payouts when the bonus features come into play. It is only here that you can win up to 10,000x at max bet.
Outside of the special features, the standard bet payouts are exactly the same as European Roulette.
