SG Digital brings you this fierce, exciting multi-reel action game with a slightly retro feel and nostalgic symbols. The Stack Em Up symbol is what it’s all about, giving you extra ways to win. This online slots Ontario classic has a massive maximum win of $250,000 up for grabs! Like we said, things really heat up fast in this game!

This is a feature heavy game with some unique bonuses that bring on the big wins. So, let’s not waste any time and get into the feature round details.

When the Stack Em Up symbol becomes visible on an active reel set, it triggers an additional reel set. Any wins on the additional reels are paid out and if you get another Stack Em Up symbol, another reel is activated. If all four reels are active, additional symbols will create win multipliers. The Stack Em Up symbols can appear at random on any reel at the beginning of any spin and serve as this slot’s Scatter.

With every cascade, you get closer to bonus spins kicking in. The more consecutive wins you get, the more bonus spins you’ll be gifted. This is how it looks when you’re on a roll with consecutive wins:



- 5 wins - 6 spins

- 6 wins - 8 spins

- 7 wins - 10 spins

- 8 wins - 20 spins

- 9 wins - 50 spins




Any of the active reel sets and win multipliers will carry into your bonus spins.

This Wild symbol (777) substitutes for all symbols except Stack Em Up. During the bonus spins round, a multiplier is applied to any win and will increase whenever a cascade is triggered. This is limitless in terms of winning as you get an extra 1x multiplier with every win.

This slot was released at the beginning of 2021 and is a follow up of the original slot, which was released in 2017. It’s got the classic feel of an old school slot but there’s a lot going on with the flaming bonus spins ladder and multiple reels waiting to trigger. It’s a wild, fiery game but remains somehow subdued with the typical 3 reel soundtrack. It’s a nice mixture of madness and mellow.
