Chests of Plenty Slot by Playtech

Two scatters, two entirely separate pick rounds, and between them they do most of the work. A gold treasure chest is one of them; land three or more and the Treasure Chest Bonus opens. You pick chests, and each one you crack reveals three gems. Match three of the same gem and that chest pays out. The other scatter is a rolled-up map scroll marked Bonus, and three or more of those send you to the Treasure Island Bonus, an interactive island trail where you move around the map collecting rewards as you go. There are no free spins anywhere in this one. These two pick rounds and the jackpot are the features, and that's it.

The top symbol is Chesty, a blonde pirate in a feathered hat with a flintlock pistol in one hand, stamped WILD. She substitutes for everything except those two scatters, and she pays the most on her own too: five of her across a line returns 10,000x the line bet, not the total bet, which is the distinction that matters when you read that number.

A progressive jackpot sits above the reels as well, tracked on a bar flanked by two gold cannons. Be clear about it though. It doesn't show and can't be won in fun-money play, only for real money. And this is a dated 2011 classic, built by Playtech's Ash Gaming studio, and it plays like its age. No free spins, no bonus buy, no ante, and the return sits noticeably below what a modern slot hands back, so you're spinning toward the two pick rounds and the jackpot rather than grinding out base-game line hits.

The setting is a sunlit tropical island: pale turquoise shallows, palm trees leaning in from both sides, a bleached skull half-buried in the sand below the reels. Those reels sit inside an ornate red-and-gold carved border, the icons drawn on aged map parchment. A-K-Q-J-10 royals share the paytable with a black-bearded pirate in a red bandana and eye-patch, a pair of crossed cutlasses, and a scarlet macaw perched on a branch.
