Above is the free Crystal Waters
slot, an often overlooked but entertaining free spin slot made by RTG and available to play online at the casinos listed here.
To get the feature, you need 3 or more scatters in view and you are awarded 15 free spins with all wins doubled. Aditionally, an extra wild symbol with a "random multiplier" is added to the center reel and you can multiply each win during the free spin bonus by up to 8x.
Crystal Waters is a pretty decent slot and one I play a fair bit, although like most of play for fun slots
here, it can be a bit streaky at times, especially if you don't hit the free spin feature for while but that's because RTG do like their higher variance games! You have to learn to be patient and wait for the bonus round if you want to win on this game.
Fans of Crystal Waters and in particular the free spins bonus round might want to also try Cleopatra's Gold
(15 at 3x) or Achilles
which has two free spin features with multipliers of 2x and 3x.
