Stack 'Em

Stack 'Em is a cluster pays slot, where winning combinations are created with a cluster of five or more of the same symbols. The bigger the cluster, the bigger the payout.
The symbols have zero coherence and that's what's so nice about it. From old-fashioned letters to thumbs up, dead birds, snakes and skulls. Who knows may say.
Winning combinations stand and fall down. After this, new symbols appear on the playing field, while a multiplier is simultaneously built up.
As long as new same symbols fall, this process is repeated.
You can bet from 0.20 euros per spin and that goes up to 100 euros per spin.
Don't be fooled by the cute Canny the Can and his mischievous Mona the Mouse: despite the lovely character, this is a slot with a very large variance.
It is possible to win up to 10,000 x the stake, but that also means a lot of dead spins and bonus rounds that pay out below par.

As with all Hacksaw Gaming games, Stack 'Em can only really come to life if you win the free spins bonus.
The bonus is activated by spinning 3 scatters or by purchasing the bonus for 129 x the total bet.
You get 5 free spins in the form of lives. The number of hearts at the top of the playing field indicates how many lives you have left.
During the free spins, winning combinations no longer disappear, but they do ensure that the multiplier grows.
As soon as you make a winning combination that has an “X” attached to it, the payout of this combination is multiplied by the total multiplier.
And then there are extra boosters that you earn by spinning the question mark:
Additional multipliers
The total multiplier is multiplied
You get extra lives
Because of the question marks, you can not only increase the multiplier in record time, but also earn retriggers.
Multipliers of x 1,000 are absolutely achievable and it just goes to show how volatile Stack 'Em is.
