How to play Blazin’ Hot 7s Stack Em Up mobile slot

Want to play on not one, not two, but four slot machines at once? Maybe get up to 10x multiplier? And have some free spins? Welcome to the Blazing Hot 7s Stack Em Up slot.

Did you love the classic Blazin’ Hot 7s slot? What? Never heard of it? Well, don’t worry. You’ll want to play on this new version which just stacks em up with more and more bonus games. Quite literally.

You play on one set of 3 reels with 5 paylines full of cherries, melons, plums, lemons and oranges as low paying symbols. Then you have Double Bar, Bell, Stars and 7s as the high paying ones.

The triple 7’s symbol is the wild symbol and if you get just 3 of those symbols on one of the paylines you’ll walk away with 500x your bet. And that’s just to start.

Play on ALL the Blazing Hot 7s Stack Em Up slots

There’s four in total that you can play. How do you unlock them? By catching a scatter symbol on an active reel set. This will open up a new set of reels above, with its own 5 paylines and same paytable.

So now, for the same price, you are playing on two slot machines. And you get that second reel open for a single spin, unless you get another scatter and open another game set.

You can open up as much as four slot machines as long as you keep catching more scatters, and if you open up all games, you then get a multiplier for each scatter you catch.

We haven’t even mentioned the avalanching spins and the free spins

If that got you excited, we should point out that opening up more than one reel set isn’t the easiest thing in the world especially in the base game. However, the Blazing Hot 7s Stack Em Up slot has cascading spins on every spin, making even one reel set interesting enough to play.

The real place where you might get those big reels and big multiplier is in the free spins game. Why? Because once you’ve opened up a reel set, it will stay open for the remaining of the bonus games.

How do you trigger the bonus? By getting 4 or more wins in a row. You’ll hopefully catch 6 to 8 free spins, up to 50 if you are lucky. And then things get interesting as the games open up and catching those big multipliers become a real possibility.

This Blazing Hot 7s Stack Em Up review gets 4 stars for surprising us and being fun. But if you don’t love the feel of a classic slot spin, you won’t love this mobile casino game, so you may want to go check out the Bull in a China Shop slot instead.

Bonus Features

Wild: The Triple 7 symbol is the wild symbol and substitutes for all symbols except the Stack Em Up Bonus.

Stack Em Up: If this is in view on an active reel set, an additional reel set will be activated. If all four reel sets, any subsequent Stack Em Up symbol will increment a win multiplier which is applied to all wins. It's a scatter and pays on any reels.

Cascading Reels: Every win will see the symbols explode and more tumble down from above, giving you another chance at a win.

Free Spins: Every cascade gets you one rung closer to triggering the free spins. The more wins in a row you get the more free spins you'll trigger.

  • 5 wins: 6 free spins
  • 6 wins: 8 free spins
  • 7 wins: 10 free spins
  • 8 wins: 20 free spins
  • 9 wins: 50 free spins

During the free spins, any new reel set you catch will not reset on a loss. Instead it will continue, with a maximum possible multiplier of 10x.

Blazin’ Hot 7s Stack Em Up Review Conclusion

The Blazing Hot 7s Stack Em Up slot will get you watching eagle-eyed for those scatter symbols so you can unlock more and more reels and more and more wins.

This is a fun little game that took us completely by surprised, mostly because we had no expectations.

So when we opened up this 3 reel classic slot with cascading reels, wilds, and the potential to open up four games with big multipliers, we had great fun.

It's something of a mix between a video slot and a classic slot, and we think you'll have fun, especially with that high RTP of 96.06% and a minimum bet of 0.20 a spin.
