RoboJack Slotby Microgaming

This little beauty from Microgaming Systems might look like a tame 20 or 25 payline slot with five reels and three positions each – but all the stops have been pulled out and it really offers 243 virtual paylines from left to right. There's no sense drawing all those lines, it's simply a matter of matching symbols landing on adjacent reels. Scatters figure prominently in this game – each additional scatter yo land will open up feature opportunities.

Land 3, 4, or 5 scatters and one of five robots will be randomly awarded – each as its own features. Accept the robot offered or decline in hopes of a better offer. You can receive extra wilds on up to 60 free spins, a wild reel on 4-20 free spins, 3x multipliers on 10-65 free games, or activate the free spins to retrigger with only 2 scatters rather than 3. Each retrigger adds 8 games.
