Alibaba's Cave of Fortune Slot by PG Soft

Coin symbols land during normal play carrying values between 1x and 10x, and when a Collector appears on the same spin, it scoops up every visible Coin value and pays the total. That interaction works in the base game too, not just during the bonus - so a Collector on reel 3 sitting next to a few scattered Coins already produces a small hold-and-collect payout before the feature even triggers. Six or more Coins in a single spin open the bonus round, but there's a wrinkle: landing only 4 or 5 Coins gives the game a random shot at adding enough extras to push you over the threshold. It's a fudge factor, basically. Sometimes you're one Coin short and the game tops you up, sometimes it doesn't.

Inside the bonus, every position on the grid is either a Coin (1x-10x), a prize tier symbol (Mini at 20x, Minor at 50x, Major at 500x, Grand at 5,000x), or a Collector. You start with 3 spins. Each Collector that lands gathers the values from all visible symbols on the board, then transforms into a new Coin or tier symbol itself - so one Collector doesn't just pay, it also adds permanent value to the grid for the next Collector to scoop. And every Collector resets the spin counter back to 3. That reset loop is where the 10,000x ceiling lives, since the bonus only ends when three consecutive spins produce zero Collectors. Desert gold and Arabian stonework fill the background, with treasure piles glowing beneath torch-lit cave walls - a similar vibe to Ali Baba's Bounty but rendered in PG Soft's rounder, more saturated mobile-first style. Wilds cover reels 2 through 5 in the base game and substitute for everything except Coins and Collectors, though they're mostly a supporting act. The Collector loop is the game.
