Crystal Hall

Play'n GO folds a nightclub disco theme into the fruit-machine format for Crystal Hall, trading the genre's usual plain visuals for neon lighting, glowing reels and a retro soundtrack. Traditional 10-through-Ace symbols make up the low end of the paytable, while poker chips, diamonds and other disco-styled icons carry the premium payouts, with a full line of top symbols worth up to 50x the stake and lower combinations returning between 2x and 5x.

The base game runs on 1,024 ways to win, a figure the free spins round later expands to 3,125 by adding an extra row to the grid. Wins form from matching symbols landing from the leftmost reel, and a wild - restricted to reels two, three and four - substitutes for everything except the scatter and the Poker Chip symbol.

Landing a Poker Chip on reel three, its only possible position, triggers the Spotlight Glow feature, dropping anywhere from 3 up to 20 Neon Frames onto random positions; every symbol caught inside one transforms into a single matching symbol type, opening up new combinations; the feature is live whether a spin is in the base round or the bonus. Three Golden Disco scatters landing on reels two, three and four trigger Disco Shuffle, which hands out either an instant Fortune Roll prize worth 5x to 200x the total bet, or the Crystal Free Spins round.

Crystal Free Spins opens with 8 spins and immediately expands the grid by a row, taking the ways to win up to 3,125; 777 symbols upgrade to Diamond 777s that pay double for the duration. Spotlight Glow also returns here with a twist - one to four Neon Frames stick to the reels for the whole round rather than resetting each spin, and turn into a single symbol type once the spins run out. Landing a Crystal Disco scatter during the round adds an extra spin, with the total capable of running as high as 46.

Crystal Hall's default RTP is 96.2%, adjustable down through 94.2%, 91.2%, 87.2% and 84.2% depending on where it's offered. Volatility scores 7 out of 10, roughly 1 in 2.68 spins returns a payout, the maximum win reaches 50,000x, and stakes run from 0.10 up to 100.
