Kroonjuwelen Slot by Pragmatic Play

Four progressive jackpot tiers sit above the reels - MINI, MAXI, MEGA, GIGA - and any spin can randomly open the pick-and-reveal screen. Twelve card symbols (J, Q, K, A) appear face-down across a grid. Match three of the same suit and that determines your tier: three Jacks award MINI, Queens give MAXI, Kings unlock MEGA, and three Aces pay the GIGA, which has climbed into the millions. The mechanic is shared across the entire Oranje Jackpot network, so the same GIGA pool feeds from every connected title - Sweet Bonanza Holland, Gates of Olympus Holland, Fruit Feestje, all of them.

Outside the jackpot trigger, the base game is about as stripped-back as modern slots get. Five paylines. Wilds only appear on reels 2, 3, and 4. Scatters pay in any position. No free spins round, no multiplier system, no bonus game of any kind. The tiara symbol at the top of the paytable pays 1,000x for five-of-a-kind, and the next highest drops to 200x - a steep cliff that makes that top combination feel almost like a mini-jackpot itself. The ring is the only symbol that pays starting from just two on a line, which keeps the reels from going completely dead on shorter combinations.

Royal purple backgrounds, gold-trimmed reels, and a symbol set built around crown jewels, emeralds, diamonds, and crossed swords. Built for the Dutch regulated market after the Netherlands opened online gambling in late 2021, Kroonjuwelen sits at the simplest end of the Oranje Jackpot lineup. Where other games in the network keep their original mechanics intact (tumbles in Sweet Bonanza Holland, the Gates multiplier system), this one strips everything to a classic payline format and lets the network progressive carry the weight.
