BGaming's mystical fortune slot with expanding symbols during free spins, high volatility, and a powerful 5,000x max win potential.
Crystal Ball is BGaming's answer to the "book slot" format that's dominated the industry for years. If you've played Book of Dead or Book of Ra, you know the blueprint: scatter that doubles as the wild, free spins with a randomly expanding symbol. BGaming took that proven formula and wrapped it in a fortune-telling aesthetic -- crystal balls, mystic smoke, and a dark purple palette that looks genuinely striking.
What sets Crystal Ball apart from the dozens of similar clones is the 5,000x max win. That's a serious ceiling for a book-style slot, and it gives the free spins round genuine stakes. High volatility means you'll need patience -- the base game can be quiet for long stretches -- but when the free spins land and the right expanding symbol is chosen, this slot can deliver some of the biggest single-round payouts in BGaming's catalog.
Players have always thought BGaming's version of this mechanic is underrated. The visuals are polished, the maths model feels fair at 96.00% RTP, and the expanding symbol feature during free spins generates that same tension that made Book of Dead famous. If you're a fan of the format but want something that feels different from the Egyptian theme that everyone's already played to death, Crystal Ball is a solid alternative.
Crystal Ball uses the classic 5-reel, 3-row setup with 10 fixed paylines. All lines are always active, so you just set your bet and spin. Wins count left to right starting from reel one, and you need at least three matching symbols on an active payline for a payout. The crystal ball symbol acts as both wild and scatter -- it substitutes for everything on paylines and triggers free spins when you land three or more anywhere on the grid.
The betting range is flexible enough for most players. Controls are standard BGaming -- clean, modern, and responsive on both desktop and mobile. There's an autoplay option with stop conditions, and a quick-spin mode for faster sessions. The paytable shows the fortune teller as the highest-paying regular symbol, followed by various mystical items like tarot cards, potions, and candles. Card royals round out the lower end.
The free spins feature is the heart of Crystal Ball, and it works like this: land three or more crystal ball symbols anywhere on the reels to trigger 10 free spins. Before the round starts, one symbol is randomly selected as the special expanding symbol. During free spins, whenever this chosen symbol appears on a reel -- even just once -- it expands to fill all three positions on that reel.
The expanding symbol mechanic is what makes or breaks your free spins round. If the fortune teller (highest-paying symbol) gets selected and appears on multiple reels, you're looking at massive payouts across all 10 paylines simultaneously. Picture three reels fully covered by the fortune teller -- that's wins on nearly every payline at the top multiplier values. This is how you reach that 5,000x max win.
You can retrigger free spins by landing three or more crystal ball symbols during the bonus round. Each retrigger adds another 10 spins, and the same expanding symbol carries over. The retrigger is rare but game-changing when it happens -- 20 spins with a high-value expanding symbol is where the biggest results come from. There's also a gamble feature after any win where you can try to double your payout by guessing a card colour, but Consider be cautious with it after a good free spins round.
Crystal Ball is available at SlotLair Casino in both free demo and real money versions. Given the high volatility, Consider strongly recommend starting with the demo. You'll want to see how the expanding symbol feature works in practice and get comfortable with the rhythm of the game before committing real funds.
