Mighty Arthur slot

Might Arthur video slotYou will need to start Mighty Arthur slot. This slot is devoted to cult legends of old England, to the first Knights-Britons and their brave leader – King Arthur. A lot of novels and movies have been created about the valour and courage of this wise ruler. King Arthur threw himself into the battle with excitement and always won. Despite all the familiar topics, the slot uses special options. Immediately two symbols can expand, and one of them can take 3x3 cells at once. You can also win free spins. RTP is 96.94%. We offer you to get familiar with all the rules that are in the game.

Review and recommendations from the testing team

  • Mighty Arthur slot has gained great popularity among players. Its many different types of bonus features, as well as the potential to make full screens of wild symbols combinations (or top symbols), but, unfortunately, this does not give a huge win. Even with that said, the slot still has the potential to trigger a series of medium size wins. I also want to note something right away, this is one of the few slots from QuickSpin company that keeps its balance very well and allows you to play a long series of spins.
  • In the usual spins without triggering the bonus feature, the slot gives out only small wins, with prizes for normal bet size to just a few bets, less often payouts are up to 15x bets (it was not possible to win more than 15x total bets in the usual spins without bonus feature).
  • The “Arthur Expanding” feature is triggered when a full (whole reel) symbol of Arthur is shown, which will then expand the neighbouring reels (2nd and 4th) to a size of 3 * 3, and acts as a wild symbol. The final payout will depend on the symbols that are given on the first and fifth reels. On average, winnings vary from 25x to 60x bets, and only once, during testing, we managed to get a win of more than 100x. This feature triggers, in the usual spins most of the time, and less often during free spins.
  • The “Merlin Random Wilds” feature is triggered when Merlin symbol appears on the playing reels, which can be shown, as a full-reel in the size of 1 * 3, and then the bonus feature is triggered directly, or as a smaller-sized, and then the slot can do both - push it until it is made full or leave it in place, like in Sakura Fortune slot. When the “Merlin Random Wilds” feature is triggered, Merlin generates from 2 to 6 additional wild symbols that are randomly placed on the reels. Merlin himself (full-sized reel) is also staying on the screen as wild symbol. The average win when this feature is triggered varies from 1x to 15x bets, and less often - reaches 30x-45x. The maximum payout received is 60+ bets. The potential of this feature is better realized during free spins, where 2 Merlin symbols are already shown, also can catch full-screen wild symbols.
  • Free spins are triggered, often once on every 50-150 spins, but sometimes, at longer distances, and in this case, Mighty Arthur slot will give do triggers almost in a row. During free spins, bonus features from usual spins are all out in play, while Arthur Expanding less often and “Merlin Random Wilds” is more often triggered. The average win during free spins is 40x-90x bets, less often - the slot gives out "empty" free spins with a total payout of 10x-25x total bets. More successful free spins (with two Merlin Random Wilds) gave out winnings in the range of 100x-170x bets (and such wins are not uncommon for Mighty Arthur slot), and the maximum payout recorded by the provider was 250+ bets.

As I said in the beginning, Mighty Arthur keeps its balance very well because the bonus features are triggering often, therefore it may well be recommended playing bonus money, but, with the exception of times when the slot machine is “cold”. While playing for real money, I would recommend leaving Mighty Arthur after a series of average wins, not trying to wait for the top combination, since this can lead to a negative result. The progressive betting strategy is also not recommended.
