Zalatar Slot by Endorphina

Three orbs float above the reels, red, green and blue, and each one hides a completely different bonus. Colored TOKEN symbols land in the base game and drift up toward the orb that matches their color, but the count doesn't decide anything. The trigger is random. An orb fires when it fires, only one can go off at a time, and you never pick which of the three bonuses you're about to play. It picks you.

Red opens a Collect round on a 3x3 grid. One collector coin locks into the centre column and stays there for the whole feature, soaking up the value of every regular coin that lands around it, anywhere from 1x up to 15x the bet each spin. The gem coins are where it climbs fast: emerald at 25x, sapphire 50x, amethyst 100x, ruby at 200x. You start with three respins and every fresh coin resets them.

Green runs a 12-spin Multi round instead. Its bonus symbols carry values that reach x200, and a multiplier in the middle cell can lift a spin's whole haul by as much as x100. That same central slot also drops mystic respin symbols worth one or two extra spins, so a hot run stretches well past twelve.

Blue is the straight jackpot chase. Fill five coins of one type to bank its fixed prize, MIN 20x, MID 50x, MAX 150x, or ULTRA at 500x, with the reels turning until you've collected at least one and then handing over a single last spin. Sitting apart from those fixed tiers is a pooled set of progressive Grand, Major and Minor jackpots that can drop at random during normal play, tilted toward bigger stakes.

Three scatters skip the wait and open a Mystery Pick'em: three cards, each hiding one of the orb colors, and whichever you flip decides which bonus starts. Don't want to wait for that either? The Bonus Pop buy option purchases the same pick round outright, though some casinos switch it off. Any win outside the jackpots can also be run through a card gamble, doubling up to ten times, with the joker beating everything.

The setting is a lantern-strung Arabian bazaar at night, cobblestones and bunting behind a turbaned fortune-teller who hovers his hands over the glowing orbs. The reels carry a golden sun face, a purple crescent moon, a green jeweled tree, a blue compass medallion and gem-cut royals, plus a red question-mark tile for the mystery symbol. The look is strong. That random trigger is the sticking point, though: you can't build toward a bonus by stacking tokens, you just wait for the genie to decide which orb lights up.
