Rolling Dunes is an eight-marble race over a track of rolling humps, filmed in 155.io’s studio. Despite the name, and despite what some sites claim, it isn’t a CCTV feed of a real desert. It’s a marble race, with the same bets and rules as Marble Plinko.
How Rolling Dunes works

Marble race rules and bet types
Winner: pick the marble that finishes first.
Straight Forecast: pick first and second in the exact order.
Reverse Forecast: pick first and second in either order.
Tricast: pick the top three in the exact order.
Combination Tricast: pick the top three in any order.
A marble that leaves the track or gets stuck is disqualified and placed at the back of the finishing order. If too few marbles finish, the race is cancelled and all bets are refunded. Each race result is tied to a seed that's committed before betting closes, so you can verify it after the race.
Lightning Rounds and boosts
Multipliers are fixed, and each option's RTP is simply its multiplier times its true chance of winning. On top of that, random Lightning Rounds boost one option's multiplier. The boost stays hidden until betting closes, and only one Lightning tier can apply per round. Win and loss streak boosts and player-level bonuses can stack on top, with payouts capped at the casino's maximum. The published RTP figures include Lightning Rounds but not streak or level bonuses.
