Enjoy an audience with King Colossus in this 5 reel, 40 payline, slot from Quickspin. Celebrating gold and riches, this royal adventure comes with a free spins feature that offers extra wilds and a massive 3×3 king symbol which can deliver spectacular results. Playable across all devices, pay homage to his highness from between 40p and £120 per spin.

Quickspin video slots are usually well presented and that’s most certainly the case in King Colossus which looks excellent. Joining the lower value playing cards are a trio of gemstones and the King. The roaring lion is the wild, substituting for everything bar the scatter and +1 symbol.

Pastels dominate the reels and it’s all very tastefully done, especially considering that the theme is gold and riches. The action plays out to a stirring soundtrack with epic blasts of brass heralding your wins. The gameplay is silky smooth, even when you opt for Fast Play mode.

King Colossus is all about the Free Spins feature – to trigger it, you’ll need to land the bonus symbol on the middle 3 reels during the base game. You’ll then be granted 5 free spins. That sounds like a miserly amount but don’t be fooled, they can deliver some fantastic results.

The first thing you’ll notice in the feature is the addition of up to 3 extra wilds on reels 1 and 5 which makes forming winning combinations that much easier. You’ll see too the giant face of King Colossus himself spinning around the reels in a giant 3×3 configuration.

If you land the King in all of his full glory, complete with the added wilds, then some truly spectacular payouts are possible. There are also +1 symbols spinning around the middle 3 reels during the feature which do just what you’d expect them to, adding an extra free spin to your tally. Simple it may be but this feature is a cracker.

King Colossus sits fairly high on the volatility scale with the variance on the high side of medium – expect plenty of near misses in the base game. Where this slot really excels is in the feature. You’ll need to show some patience (and have the bankroll to cope with those potentially big swings) but if King Colossus himself puts in an appearance, there are some colossal opportunities available. If you like big block wilds, NetEnt’s Spiñata Grande offers a 3×3 wild in the free spins feature.
