Kings of Crystals

Kings of Crystals is a medieval fantasy-themed slot developed by All41 Studios in partnership with Microgaming. The game is set in a mystical realm where three kings seek their crystal crowns. The visual style combines regal elements with magical crystals, creating a blend of medieval and fantasy aesthetics.

The main characters are three distinct kings, each associated with a different color: red, blue, and green. These monarchs are prominently featured on the reels, with the blue-haired king notably standing out with an almost alien-like appearance compared to his more traditional counterparts. The game's backdrop depicts a castle interior, reinforcing the royal theme.

Core Game and Mechanics

Kings of Crystals plays out on a 5-reel grid with an initial 4-row setup and 40 paylines in the base game. During certain features, the grid expands to 5×6 with 100 paylines. The game boasts a high volatility and offers multiple RTP settings, with the highest being 96.40%.

The base game focuses on landing winning combinations of symbols, with premium symbols paying 2.5x the stake for five of a kind, except for the green King symbol, which awards 5x for a full line. Wild symbols appear on reels 2, 3, and 4, substituting for regular pay symbols to form winning combinations.

A key mechanic is the scatter collection system. Red, blue, and green crystal crown scatters are collected in separate meters, eventually triggering corresponding bonus rounds or combinations thereof.
