How To Play Rainbow King Slot

The base game is a standard 5 x 3 reel structure with 20 paylines.

While 20 paylines aren’t as impressive as some of the modern games, it’s so much easier to keep track of the game, and it allows for greater flexibility when betting.

The minimum stake for this game is £0.01, and the maximum stake is £100, giving you a wide betting range.

You can adjust your coin values to be as little as £0.01 or as much as £5, and you can bet on as many paylines as you’d like, the minimum being one and the maximum being 20.

There are seven paying symbols in the game, with the most valuable being the multicoloured Wild symbol. Matching five of these symbols pays out 2,500x your stake, so look out for those!

The second most valuable symbol is the Bag of Gold, which pays out 1,250x your stake if you match five in a row.

There are three other symbols in the game that unlock Bonus features, and you’ll need to hit these Bonus features if you want to take home the 12,500x max win.

Rainbow King Slot Features

The Rainbow King online slot game is chock-full of great bonus features, so let’s dive right in!

Cash Castle Bonus

If you find three or more Castle symbols on your game board, you unlock the Cash Castle Bonus.

In this bonus round, you must select one of the castles on the board to reveal an instant cash prize.

King Cash Bonus

If you find three or more Crown symbols on your game board, you unlock the King Cash Bonus.

You’ll be taken to a second screen, where you pick from one of 12 crowns to win an instant cash prize.

Prizes range from 100 credits to 1,000 credits, so there’s potential for a huge win.

Rainbow King Bonus

If you find three or more of the eponymous Rainbow King symbols on your game board, you unlock the Rainbow King Bonus.

You’ll then be taken to a large game board, where you can roll a die, move around the board, and collect cash prizes.

Reel King Spins Bonus

If you pick up Reel King Spins in the Rainbow King Bonus feature, you’ll be taken to an additional bonus round.

You’ll then be greeted by four Kings, each holding three-reel slot machines.

You can spin each of these slot machines to unlock a prize, with a maximum of 2,500 credits per King available to win!

Rainbow King Slot RTP & Volatility

One area the game is lacking is its return to player rate. With an RTP rate of just 95%, it’s below the average rate of 96% that we’d expect to see from an online slot.

However, this slot is low volatility, making it ideal for players who prefer more regular, smaller wins.
