Colossus Kingdom Slot Review

Released April 2019

The Colossus Kingdom slots game can be found at casinos offering Spinomenal software. Spinomenal is one of the newer software developers in the online gaming market. Alongside many of the smaller casino software providers Spinomenal focus heavily on slots games. The House Edge/RTP of the Spinomenal slots games is listed within the paytable for the newer games in their catalogue. For the older games, as Spinomenal is partnered with UK licensed operators and the UKGC license requires the publication of this information, RTP figures can be found on numerous casino sites. As such, we know that the house edge for Colossus Kingdom is 4.8%.

Colossus Kingdom is a 5-reel game that is 3 symbols high on reels 2, 3 and 4, with reels 1 and 5 being 4 symbols high. This means that colossal 3x3 symbols can be formed in the middle 3 reels. The game uses traditional paylines with 20 in total, playing from left to right.

Special Symbols

Wilds – The game’s Wild symbol is the “Wizard”, which will substitute for all symbols other than Free Spins and Bonus symbols. 5 Wild symbols on a winning payline will award a x160 multiplier.

Free Spins– The Free Spins “Castle Gate” symbols will trigger the Free Spins feature if you can reveal a colossal 3x3 symbol on the middle reels. This is only available during the base game.

Bonus – The Bonus is triggered when you land a 3x3 colossal “Bonus Wheel” symbol on the middle reels. This is only available during the base game.

High Paying Symbol – Along with the Wild symbol the two most valuable symbols are the “Dragon” and the “King”. 3 of them as part of a winning payline will pay out 25 times the bet; 4 will pay out 50 times the bet and 5 as part of a winning payline will pay out 160 times the bet.

Bonus Features

Mystery Symbol – After the reels have stopped spinning, if there are any Mystery symbols left on the reels they will uncover and reveal 1 normal sized symbol.

Colossus Spin Feature – The Colossus Spin feature can randomly appear when the reels are spinning and reveal a 3x3 Colossal symbol on the middle 3 reels. This does not apply to Wilds, Bonus or Free Spins symbols.

Colossus Symbols – Other than the Wild symbol, any other symbol may appear as a Colossus 3x3 symbol on the middle 3 reels.

Nudge Feature – If on 2/3 of a Bonus or a Free Spins feature lands on the middle 3x3 reels, then there is a chance that a Nudge can occur that will push the symbol down and fill the reels.

Gamble Feature – When you trigger the Free Spins feature you can gamble the Free Spins that you have won in an attempt to win up to 40 Free Spins. You can gamble a set amount and then choose which side of the coin you think will land when it is flipped. Win and you double your Free Spins. Lose and you lose everything you have gambled.


Colossus Kingdom is a brightly coloured game set in a world of wizards, dragons, kings, queens and castles. There is a cartoonish look to the game that brings a degree of fun and light-heartedness to the experience. The game has plenty of special features to offer, with the stand out feature being the 3x3 colossal reel in the middle of the reels. The house edge needs to be a fair bit lower, but is still less than many of Spinomenal’s games.
