Triangulation from Microgaming is one of very few slots that has some kind of skill element to it. This comes in the bonus round when you have to select the best possible combination of triangles to swap out for wilds. In the video below the player has in fact picked one of the worst possible combinations. Pause the video at 29 seconds and you can see that picking the 3 triangles on the left would have resulted in a much much greater combination of 4 x 4 plus 5 x 2.5 rather than the 8 x 0.2 they selected. So you can see that by playing smart they could have increased their total win from 1.6 times stake to 28.5 times stake. This is a slot that requires you to think and we enjoy that element.


#8: Spartacus online slot (WMS Williams Interactive)

Colossal Reels Spartacus Gladiator of Rome Slot Machines by WMS Gaming (to give it its full title) is our favourite Williams Interactive online slot. It features 5×4 and 5×12 Colossal Reels sets which combine to offer up to 100 lines of high-volatility action!
This slot is one we enjoy spending a lot of time on. The bonus feature can pay really big sums on occasion but most of the time it doesn’t bring home too much bacon. However it is the fact that during the normal mode you can regularly get decent sized wins that keeps this slot ticking over. We tend to be a little less cautious with this slot compared to some of the really high volatile slots you will find on our top 30.
Below you will find the official video from Williams Interactive which is showing you the bonus round.


#7: Transformers Battle For Cybertron online slot (IGT)

We liked themed slots here at Slots Guide and this Transformers slot from IGT is another good one. This time featuring the free fall type of slot, there are plenty and regular mini features to keep your balance and entertainment levels ticking along whilst the main bonus game gives you 4 options to choose from and we appreciate slots that let us take the extra gamble of picking which bonus to take.
