Ra KO is an online slot developed by Green Jade Games. It has 50 paylines, 6 reels and an RTP of 96.098%. It has an Ancient Egypt-inspired theme with bonus features including wilds and multipliers.


A sandstorm is not normally a good thing but it is in this 6-reel, 50 payline slot from Green Jade Games. Take advantage of multiple wilds that can arrive on any spin, as well as Ra’s Bonus Reels, offering prizes of between 2x and 2,000x your stake. 

The slot offers an RTP of 96.098% and is a highly volatile game, which is often the case with slots of this type.

Theme, Graphics & Soundtrack

This is an Egyptian-themed game in the same vein as the Gold of Ra slot. It revolves around Ra, one of Ancient Egypt’s most important gods who was said to be the God of the ky, the sun, kings and order. He is notable for his falcon head and sun disk within a cobra which sits on his head. In this slot, he stands on either side of the reels, presiding over the action. The Ancient Egyptian theme is strong and is highlighted when a sandstorm blows across your reels and leaves a trail of wilds in its wake. It isn’t a new theme - or design - but it does work well, and the bouncing background music does a good job of transporting you back in time.

How to Play Ra KO

Green Jade Games slots are as pleasant to play as they are easy-on-the-eye. To get you started, here are some tips:

  1. Locate the spin button in the centre under the reels.
  2. Click on the top tab on the left of the spin button to use the autospin function and to decide how many games you want the slot to play automatically and when you want it to give you back control.
  3. The tab below the autospin button allows you to speed up the action of the game if this is how you prefer to play.
  4. Use the up and down arrows on the right-hand side of the spin button to decide how much you want to stake on each game. Bets start at 0.50 and go up to 25.00 per spin.
  5. Fun comments are displayed in a box above the reels, such as ‘By the power of Ra!’. Above this comments box is where you will find the settings menu tab.
  6. Use the hexagonal settings button to turn the soundtrack and music on or off.
  7. This menu is also where you will find the help section. This is where you will find a range of information, including the paylines on offer and the game’s paytable featuring possible prizes.
  8. Use the arrows at the bottom of the help screen to scroll through the 13 pages of information.
  9. Remember to always play responsibly. Decide on a budget and stick to it.

Bet Sizes & Paytable Wins

Unlike with some online games, you don’t need to make more choices than you do in the supermarket before you get to play. In this slot, you just have to decide how much you want to bet with the choices ranging from 0.50 to 25.00 per spin.

Access the paytable using the game’s help menu to see the prizes on offer, which are all displayed as cash values and change according to how much you decide to bet. Here are the top prizes available in the base game if you decide to bet the maximum of 25.00 per spin and manage to land 5 matching symbols on a payline:

Red-gemmed female burial mask - 1,000.00

Sekhmet the lioness goddess - 250.00

Ra - 150.00

There are also mid-pay symbols, offering prizes of between 60.00 and 80.00 for 5-of-a-kind and lower paying card symbols, delivering wins for 5-strong combinations of between 40.00 and 55.00.

Ra KO Bonus Features

Ras Bonus Reels can offer all sorts of cash prizes (or credits if you’re playing in free demo mode). The Bonus Reels feature is triggered if you manage to land between 3 and 6 loot boxes in a horizontal collection on a row. If you land enough but not in a horizontal row, you will get the Auto KO feature instead. If you trigger the Bonus Reels, the reels will spin and reveal a symbol, to award you with a prize ranging from 2x to 2,000x your total win. Your prizes will be revealed from the lowest to the highest. The number of prizes you receive is based on how many loot boxes you land. So, if you get four loot boxes you will get four prize-winning bonus reels.

In the Auto KO feature, Ra knocks out icons to sort out loot boxes and trigger the bonus feature. Each knockout will use up a charge and the number of these you have will be shown on a meter, either at the bottom of the reels or to the right, depending on if you are playing on a desktop or a mobile device.

This slot doesn’t have a free spins bonus but it does has a Magic Wilds feature that can be a real game-changer. If triggered, Ra will add between 4 and 16 wilds to your reels, offering substitution powers to help you to create winning combinations. 

Ra KO Review

This is quite an original take on a fairly standard theme, although the high volatility will not be for everyone. If you can stand the waits for wins, however, this a good-looking game with plenty of bonus action if lady luck is on your side. There are some decent prizes on offer, especially when the loot boxes come into play, and the RTP is about average in the world of online slots.
