Novomatic revisits a classic theme and gives it a modern twist or two in Reel King, an old-school 5 reel, 20 payline slot machine. It comes with a free spins feature that offers jackpots of up to 500 times your line bet. Play from between 20p and £100 per spin.

Reel King has been a big hit with players in brick and mortar casinos up and down the land and the online version sticks faithfully to the original. The reels are packed full of symbols you’d expect find on a classic fruit machine and include cherries, plums and a selection of playing card symbols.

The jester’s hat acts as the wild and substitutes for all other symbols. The biggest payer is the jackpot symbol. If you manage to fill all 15 reels with the jackpot you’ll be awarded a bumper payout of 500 times you bet.

The main attraction is a Free Spins feature – it’s a little different from the standard free games offering that is a staple of so many slots. The first difference is that it is triggered at random rather than having to find a series of scatters. The second is the way that the spins are awarded. Instead of being played out on the same, or even a different screen, they’re instead offered on a single symbol, the rotund King.

He expands to reveal a tiny set of mini reels, packed full lucky 7 symbols in a variety of colours. The amount won on each spin depends on the colour of the 7s. The feature continues until a spin appears that includes something other than one of the lucky 7s. When the Reel King does hit it can be extremely lucrative, offering payouts of between 5 and 500 times your total stake.

The variance in Reel King isn’t in the stratospheric range which is the case for some Novomatic slots. It’s still on the high side of medium though so some careful bankroll management is required. If you like complex feature rounds packed full of slick graphics and animations then you’ll find Reel King something of a disappointing.

Lover of old school one-arm bandits will find it much more to their liking. This game can be found in pubs up and down the UK much like Barcrest’s Rainbow Riches which is a classic.
