Jenny Nevada and the Diamond Temple Slot by Rival

Three different scatters on one reel set, which is rare for a Rival title and the first thing worth flagging. The blue Diamond pays anywhere - 3, 4, or 5 of them anywhere on the grid awards 75x, 350x, or a flat 10,000x your bet, and that 5-of-a-kind hit is the actual ceiling of the game in both base spins and free spins. The vintage prop Plane is the bonus trigger. The Jenny portrait fires Free Spins. Easy to mistake one for another in motion, so watch the labels.

Free Spins scale steeply with the trigger: 3, 4, or 5 Jenny scatters award 10, 20, or 50 spins at flat 1x, no retriggers, same reel set. The pull is that the Diamond pay-anywhere stays live during the round, so a 50-spin trigger is essentially a long lottery ticket on that 10,000x line.

The Temple Maze Bonus Round is where the design gets interesting. You enter by landing 3, 4, or 5 Plane scatters, and the trigger count determines which of three escalating tiers you play - the gap is huge. Tier 0 averages around 9x with a 50x cap. Tier 1 jumps to about 45x average, 200x cap. Tier 2 sits at roughly 90x average and tops out at 400x. Inside the round you pull levers to open temple doors, each one revealing a treasure value, and you keep pulling until you either find the Sacred Diamond (clean win) or trip a Booby Trap (round over). Eight possible picks per tier, one of which is the trap, so most runs play out before it appears.

The Bonus Buy panel offers two prices, and they sit on opposite ends of the value spectrum. The 10x bet Temple Maze entry only buys you a Tier 0 round at 94.37% return, which is the worst RTP path in the game. The 22x bet Free Spins buy lands at 96.94%, slightly above base - one of the rare buy options that's mathematically defensible.

The Tribal Mask Wild fills in on reels 2 through 5 with no multiplier attached, pure substitution. Visually the whole thing leans hard into the Indiana Jones template - red-haired explorer in khaki standing torch-in-hand beside the reels, jungle vines crawling over weathered stone columns, brass-and-gold Aztec calendar styling on the spin button. Saturday-matinee pulp, executed neatly by Rival.
