King Colossus

QuickSpin’s King Colossus online slot was released in 2014 and has attracted attention with two lucrative features that are triggered during freespins. A huge 3×3 symbol and guaranteed wilds ensure maximum winnings in bonus mode. The neat, pastel-coloured design and unpretentious theme are an added plus.

About the slot

Launching the demo and starting to play the King Colossus slot machine for free and without registration, the user sees a standard grid of fields: 5 reels with three rows of icons. Lines 40, and they are fixed. You can spend from 0.4 to 120 credits per spin in casino currency.

Combinations are only paid in one direction and must start from the left-most reel. To win, you need a continuous sequence of two or three elements on an active line.

There is no risk level, progressive jackpot or themed bonus round in the slot. The theoretical return rate (RTP) is 96.57%.

Slot machine interface

Video slot is controlled by the buttons on the bottom panel under the field. There are:

  • Bet setting (small white arrows).
  • Start of the spin.
  • Activation of autorotations, which can be stopped by condition (spending limit, winnings, number of scrolls).
  • Turbomode activation, accelerating the animation.

On the right are the technical settings buttons: a gear opens a menu where you can set the keyboard control, turn the sound on and off, and by clicking on the three white lines, help is available in pictures. The detailed rules of the machine can be explored by clicking on the question mark in the top right corner.

Thanks to the use of HTML5 technology, the game works equally on mobiles and personal computers. To run the application from the casino website, you simply need to download a modern browser.

Pros and cons

The developer has provided all the necessary features so that users can play King Colossus for money in the online casino and benefit from it. In addition, the machine has a nice design and interesting features that allow it to remain interesting even for those who prefer to bet in the free demo version.
