Chrome Comet Showdown

5 reels × 3 rows, 243 ways, left to right. Winning symbols clear and new ones fall in; each cascade in a spin climbs 1× → 2× → 3× → 5× → 8×. Wilds land on the three middle reels.

In the free spins, each free spin opens with a showdown on the reels as they land. If the Chrome Comet has more symbols on the grid than Baron Moonbolt, the spin starts that many steps up the ladder: a lead of 1 starts it at 2×, 2 at 3×, 3 at 5×, and 4 or more at 8×, and each cascade still climbs from there. Wilds count for neither side, and symbols that fall in later do not count. If the villain matches or leads, the spin starts at 1×. About one free spin in 3 starts above 1×.

3, 4 or 5 scatters on the first drop of a spin award 12, 15 or 20 free spins; 3, 4 or 5 on a free spin add that many again, up to 60 free spins in all. The feature can be bought for 16.41× the bet with 12 free spins, for 20.52× with 15, or for 27.34× with 20. Each price is what those spins return on average, less the house's share: no tier is a better buy than another.

Bought, the three return 96.40%, 96.41% and 96.39%, as measured (each give or take 0.19 points at most); most buys return less than they cost.

When two scatters are in view, the reels still turning stop more slowly. That is decided only by the reels that have already stopped and happens every time two are in view, whether a third comes or not: it says nothing about what the turning reels will show.

One spin, feature included, pays at most 6,000× the bet: a spin that reaches it stops there and is paid exactly that.

The return printed here was measured, not derived: 96.29%, give or take 0.10 points, over 60 million spins. 34.9% of spins pay something; the free spins come about one spin in 153 and pay 11% of the return.
