MIGHTY ARTHUR slot is one of my favourite slot games from Quickspin. This mythical game with its amazing graphics and animation is set around the classic characters of king Arthur and Merlin the wizard. Mighty Arthur slot has a 96.94% RTP and comes with three fantastic bonus features which include the free spins bonus feature, merlin random wilds and the king Arthur expanding wild, with the free spins feature and the king Arthur feature having the potential of giving epic wins. The maximum default win on a single bet line in the base game is 621 x your stake. The highest I have won in this game is about 210 x 40c stake which gave me a win of $84 and was won from the free spins feature where I got two expanding merlin wizards on the 4th free giving me a win of $42.

I dont know about other players but I seem to have way better luck playing the desktop version. I have played this game ALOT of times and most of my big wins have been played on the desktop version.
I also find with this slot game that if I trigger the free spins bonus round during the start of my game play, it gets re-triggered again and again easily within the first 100 spins. For me, this also applies too with the merlin wizard expanding wild feature in the base game.


With mighty arthur slot I find that if I start off on a winning roll I will keep winning and hitting the bonus features regularly for a while but if I start off on a loosing roll I could spin over 500 spins and still not hit one bonus feature at all and when I finally do trigger ANY bonus feature, the winning is always very small, usually no more than $2

I find there is very little not to like about the game Mighty Arthur by Quickspin. The gameplay is smooth, the graphics crisp and clear, the bonus round has the potential for some impressive wins and the base game doesn't lag behind much in the department either.

The Arthur symbol which drops randomly on the center reel and then expands to fill the center 3 rows can be a game changer or a game saver depending on where your balance sits when it hits for you. Having the center 3 rows all turn wild makes for some wonderful hits even with low end symbols, yet alone when it hits along with some of the top symbols.

The Merlin symbol drops randomly, making an entire row wild and can drop in multiple places at the same time.

The bonus round is 10 rounds and any time even a hint of either Merlin or Arthur show them slide down into place just as pretty as can be to form up some incredible bonus round wins.

This game in my experience is very much a "when it's hot, it's hot" game. I've taken an initial $20 deposit and turned it into upwards of $5,000 by raising the bet after every bonus round, I've also seen it eat a $50 deposit without even pretending to show a bonus round. Get it while it's hot, steer clear when it's not.


The teasing of the bonus symbols Merlin and Arthur can be a touch frustrating at times when you've gone a long cycle without a decent hit and they seem set to come in, but hover just out of reach instead. This is by design and working as intended however and just encourages the intrepid spinner to hit the spin button one more time in hopes of finally seeing the big win.
