Crystal Ball by Bally takes you to the magical world of wizards and unicorns. The game has five reels with five fixed paylines and a maximum jackpot of €10,000 per line.
The graphics in Crystal Ball are average 2D graphics that start at the bottom of the paytable with the standard poker symbols, then rise to a potion and amulet in the middle and further up to the crystal ball, unicorn and wizard. The music and sound effects in the standard game rounds aren’t incredibly inventive and don’t necessarily support the theme very well. There aren’t many animations in the game either. However, if you manage to start the free spins, the music and sound effects become much more fitting to the theme and quite lovely.
The stakes in the game range from €0.05 to a maximum of €10 per game round. The theoretical payback to the players is 96.12%.
The game’s unique features are the crystal ball, which can substitute for other symbols like a wild symbol. Three or more crystal balls are also the scatter symbol and give you a payout based on the number of symbols you can see on the screen, and you also get ten free spins. At the beginning of the free spins, a random bonus symbol is chosen, but it cannot be the crystal ball. At first, the wins of the game rounds are usually calculated, but if you get at least two or three bonus symbols anywhere on the reels, these symbols will expand and occupy the whole reel. The paylines are then recalculated, and you get a payout on scatter basis. If the wizard is the bonus symbol and there are multiple wild symbols in the winning combination, then the payout is calculated based on a unicorn combination. You can also extend the free spins with more scatter symbols. The game also offers you the possibility to increase winnings of less than €150 in one of the two risk games to a maximum of €150.
Unfortunately, the Crystal Ball slot is not yet available for mobile devices, but you can play the game on a setup or a computer. Since the game only has 5five paylines, you certainly expect the free spins to compensate for that, and I think these free spins with the bonus symbol achieve that well.
Wild symbol: The crystal ball is the wild symbol and substitutes for all other symbols for winning combinations.
Scatter symbol: The crystal ball is also the scatter symbol and gives you an instant win and free spins for 3 or more symbols.
Free Spins: With at least 3 scatter symbols, you get ten free spins, which can also be retriggered. A random bonus symbol is chosen in these free spins that can expand to other reels and thus provide multiple winning combinations.
Gamble option: there is the card risk game and the ladder risk game, in which you can wager winnings from game rounds, provided they are less than €150.
Bonus games: none
