The visuals are as expected from a Thunderkick game, slick and really well designed with the slot itself being set within a mine with an up tempo soundtrack which really helps to set the mood. Players can expect to find 4 Rocket Fellas and 4 shiny rocks on their reels and there is also a symbol represented with a barrel which is the highest payer giving players that land five across a pay line x30 of their stake. Players will also see a mining cart packed with sparkly rocks, this being the wild and able to substitute for all the other symbols with the exception of the scatter to create winning combinations, again landing 5 carts also pays out a massive x30 of the players stake. Amongst the other symbols, players should keep their eyes open for the rocket symbol which will only make an appearance on the first reel and whenever it does it morphs into a wild.
Landing the rocket and barrel symbols on the same line will also see the symbols transforming into wilds and this process is aptly named as the Rocket feature. However, it must be said that the main attraction in this slot has to be the Bonus Game feature which comes into play when three or more of the bonus symbol (depicted by an Iron Fist) appear simultaneously within a base game spin. This bonus symbol awards 10, 25 or 20 free spins for landing 3, 4 or 5 respectively. It is also important to look out for the bonus symbol as landing 2, 3, 4, or 5 will award 3, 10, 15 or 20 extra free spins bringing the total to 40. Whilst in the Bonus Game feature, landing the barrel and rocket symbol on the same row also activates the Rocket feature although the barrel will turn into a sticky wild rather than just a wild as it does in the base game.
But there is even more as there is also a Hot Reels feature where landing barrels on the same reel will see them turning from sticky wilds to regular wilds again for even bigger wins. Whilst the slot in its entirety centres around the rocket and barrel symbols that award the wilds and sticky wilds in the Bonus feature there are some excellent sums to be won. Although Rocket Fellas Inc is a high variance game players do have the opportunity to land wins that could be worth up to x7,325 of their stake on each and every spin and free spin. If you like the whole mining theme, I would also recommend you check out Diamond Mine from the developers at Blueprint Gaming as this is another highly enjoyable slot.
