To achieve a winning combo in this game, players must land three or more matching symbols on active paylines, starting from reel one.

The symbols on the reels of this game are:

Special features

There are three special features in the Olly Murs Big Box Bonus slot game including a wild symbol, a free spins bonus round and a bonus box feature.

The wild symbol is Olly Murs himself and this symbol will replace other symbols on the reels to help form new winning combinations and award big cash prizes.

To trigger the free spins bonus round, players must land three or more free spins symbols on their reels. The more you land, the more free spins you will be awarded.

  • Three free spins symbols – five free spins
  • Four free spins symbols – seven free spins
  • Five free spins symbols – nine free spins

Finally, we have the bonus boxes feature. If you land three or more matching box symbols on a win line you will be awarded a mystery multiplier for each box on that win line. Therefore, the more matching symbols you land, the bigger your prize will be. There is a red mystery box, a blue mystery box and a gold mystery box.

  • Blue mystery box – each box pays up to 100x your stake
  • Red mystery box – each box pays up to 250x your stake
  • Gold mystery box – each box pays up to 500x your stake

The gold mystery box is the key to the biggest wins in this slot game but it will only appear during the free spins bonus round.

Graphics and Sounds

The Olly Murs Big Box Bonus slot game resembles a cool Saturday night entertainment show and, of course, centres on the famous British singer Olly Murs. Behind the reels, players will see the bright lights of the studio shining down and a cartoon version of Olly appears next to the reels with a bright red suit. On the reels, the low value symbols are your standard playing card symbols 9, 10 J, Q, A and K. The higher value symbols include a range of mystery boxes that contain multipliers as well as a wild symbol with Olly Murs face. As you spin the reels, jazzy gameshow style music plays in the background which fits the theme perfectly.


Olly Murs Big Box Bonus is a fantastic slot game from Slot Factory and Heart Bingo players are sure to enjoy spinning the reels of this exclusive game. The graphics look great and the gameshow theme will remind players of the iconic Deal or No Deal with the mystery boxes on the reels. This game also offers something a little bit different with these mystery boxes but the gameplay is kept simple with wilds and free spins available. With the chance to win up to 500x your stake per gold mystery box, this can be a lucrative slot that you will not want to miss out on spinning.
