Titans of the Sun Hyperion is the first of two new video slots that recently released from Microgaming and they have same themes relative to some Greek Gods. You can play both in download mode or Flash mode, via Microgaming and Quickfire operators. This slot has 15 pay-lines and 5 reels and we can say that is a quite simple game with nice graphics and sounds and without to many animations. You have the option to click on Demo Credits to view your summery and choose to view coin, credits or both. The coin denomination is from .01 till .10 credits and you can bet up to 10 coins per each active line. You can find these options in the Bet button. The game has the regular low-pay symbols, the high playing card symbols and also medium-pay ones, like Phoenix birds, or the winged horse Pegasus and Hyperion, which was one of the 12 Titan children of Gaia and Uranus, himself. A very interesting feature is that the Hyperion symbol appears stacked on all reels. The most you can win for five of such is around 133x your total bet.Since we are also players and we already try this game we found that the most interesting feature of this game is the brand new Stacked Mystery Symbols. These icons appear as the Sun and can transform into any high or low symbol. These icons becoming even more interesting if you manage to get them during the Free Spins bonus round which you can trigger with three or more Scatters in the form of Hyperion and Theia.During this round you will get 15 free spins and as we said the mystery symbol during this round can not only transform into any high or low symbol, but also Wilds!!! The bonus round can also be retriggered with the same type of combination and can reward you up to 100x the total bet for five on a line. So if you do your math you can find that the maximum reward during this round can reach up to 75,000 credits! Overall Titans of the Sun Hyperion slot machine is a very nice game with new features from Microgaming like the Stacked Mystery Symbols which we believe that you are going to love immediately.
