Reel King is a traditional video slot machine originally made by Astra. Astra is however a sub company to Novomatic, so it's brought online by Novomatic's online division named Greentube. This is a slot machine that have been highly popular in the UK land based market for several years, but its available online for everyone to play. Reel King is actually the same slot as Win Wizard, but with a slightly different presentation of the bonus game. It's a fairly simple slot machine with a mix between single and stacked symbols. The maximal win per spin is 500x the stake during both the base game and the bonus game. The bonus game is actually known for being a bit buggy. Sometimes the bonus game refuses to load, and instead the cash prizes are just paid out without any animations. This does not interfere with the payout percentage or anything, it's just a graphical bug. The RTP for Reel King is really low at only 93.97%.

Game features

Reel King has wild symbols on reel 3, 4 and 5, and these symbols substitute for all other symbols in play. The best paying symbol is the Jackpot symbol, and it's possible to fill the entire screen with this symbol for a prize of 500x the stake. The only bonus feature on this game is a feature that is activated by sound only, yes your heard it right. There's no symbols needed to activate the bonus, you just need to listed for a sound when each reel stops. I'll explain it more in the below section. If you're a real gambler you might want to try to double your winnings in the in-game double up game that's presented as an option after any winning spin. Here you get a true 50/50 chance to double your winnings in a red/black card game, but please remember that you also risk all the winnings!

Bonus game: Like mentioned above, the bonus game is triggered in a highly unusual way on Reel King. If you play the slot with sounds muted, you have no indications that the bonus game is won until it pops up on the screen. However, if you have sounds activated, you will have to listen for a melody for each of the 5 reels. If a melody is played when each of the 5 reels stop, the bonus game is triggered. (If you are lucky, as there is a bug in this slot that sometimes don't show the animations from the bonus game, but instantly pay out the prizes that was supposed to be won from the bonus game animations). I mentioned earlier that this is the same slot machine as Win Wizard, but that the bonus game was slightly different, and here’s the difference. While Win Wizard rewards you with between 1 and 5 books that will give you different cash prizes, Reel King rewards you with between 1 and 5 mini slot machines.

Each of the mini slot machines can pay different amounts, but the total win will never exceed 500x. So if you get all 5 mini slot machines, the maximal prize is still 500x the stake. You get to spin the slot machines as long as you get a winning combination of sevens. If you look at the paytable, you will see that a combination of mixed sevens pays 2x the stake, blue sevens pays 5x the stake, yellow sevens pays 10x the stake, while the red sevens pays 25x the stake. Each mini slot machine will continue to spin as long as you get a winning combination, or until the maximal win of 100x the stake is won. The bonus ends when none of the slot machines has spins left, or when 500x the stake is won.
