About King Colossus
King Colossus online slot, which was created by QuickSpin, features a 5x3 reel set. However, the traditional number of available pay lines has been increased from 20 to 40, enhancing your winning potential. The opportunity to create ‘multi wins’ with a single spin is strong here! These payouts will soon stack up as they accumulate with each spin. Low wins come in the form of the playing card symbols, of which there are five: ten, jack, queen, king and ace. Medium wins arrive courtesy of the character symbols, which pay the following based upon an 0.80 bet per line strategy:
Symbol 2x Payout 3x Payout 4x Payout 5x Payout Emerald - 0.40 0.60 2.00 Sapphire - 0.40 0.60 2.00 Ruby - 0.40 0.60 2.00 The King 0.04 0.40 0.60 2.00 As mentioned, there is potential to pick up multiple wins per spin, so accumulating a profit is quite possible.
How to Play King Colossus Slot Online
The King Colossus slot game features 40 paylines: a number set in stone. This means players have fewer options when it comes to modifying their stake amount. Instead, however, you can use the total bet function to edit your wager from 0.40 to 120.00 per spin of the reels. What's more, QuickSpin have made it easy to zip through plenty of spins as quickly as possible – truly living up to their namesake. There is also the option to use Autoplay (10-1000 spins at the same bet per line each time), and highlight the fast forward button to bring each spin to a rapid conclusion. Lastly, you can choose to activate your keyboard when playing on desktop or tablet devices. This allows you to press space bar to spin the reels rather than having to click the spin button.
King Colossus Slot Features, Specials and Symbols
The King Colossus online slot features not one, but two wild symbols. The first, which is termed the regular wild, is a lion’s head on a green background. This substitutes for all other symbols apart from the other wild and the +1 spin icon (more on that shortly). It also pays a huge 15.00, 90.00, 300.00 and 1500.00 for matching two to five on your reels. The second wild is known simply as the bonus, and is depicted with a lion’s head on a red background. This appears solely in the free spins feature, and two will line up in random positions on reels 1 and/or 5 on each turn.
So how do you trigger the free spins round? Just reveal three or more of the scatter symbol. Here, the +1 spin symbol will (hopefully) reveal itself, adding extra free spins to your allotment, while the King himself expands to form a 3x3 block on reels two, three and four. This could be your ticket to the high life!
