Eltoreo reminds me of the game called Wild Princess which was created by Xplosive slot. Maybe they are a different gaming however the slot design, look and feel is exactly like GameArt. Anyways this 10 payline slot is not that much of interest as the bonus feature is the only thing that attracts me to this slot.
The game has a wild symbol which is the matador guy that expands to cover the entire reel. The wild only appears on reels 2, 3 and 5 during the base game and during the free spins game. The free spins are triggered when 3 or more bull symbols lands anywhere on the reels. Whether you get 3 scattered bull symbols or 5, the payout for scatter stays the same.
You initially get 10 free spins and during free spins the wilds are sticky. So, if a matador wild symbol lands on the reels in expanded position it stays there for the remaining free spins. The highlight would be get reels 2, 3 and reels 4 sticky wilds. The would maximise the win insanely. I do not think you can retrigger the feature.
I had a couple of wins over x100 my bet on this slot but never more than x200 my bet. On average you win x50 your bet. I think the game has the potential but in my opinion, should have 20 paylines lines. The slot can be very cold at times and triggering the bonus feature can take forever at times.
I still prefer Eltorero form Reel Time gaming(Gamomat). This slot has more potential and sticky wilds are on all the reels.
