Just when you thought the bonus couldn’t get bigger, you find Blazin’ Hot 7s Big Bonus, an SG Digital slot. The developers have taken a classic fruit- and 7-themed game and turned it into something way more exciting. 

As always, before you place a bet on any online slots, it’s a good idea to find out more about the game in question. So, check out this game review for Blazin’ Hot 7s Big Bonus from SG Digital.

Game Overview

Blazin’ Hot 7s Big Bonus has a pretty standard 5×4 reel layout, as well as 40 paylines. The player RTP (return to player) is 95.98%, which is almost bang-on average for slots online. 

The blazing hot 7s are the highest-value symbol, but the wild 7 also offers some sweet wins, as it turns into a sticky symbol during the free spins round. Talking about free spins, this round has a minimum win feature, which means you’ll win something on every spin. There’s also a Bonus Buy feature if you’re feeling extra lucky.

This is a high-volatility slot game with an exceptional retro feel to it. It offers players the chance of a maximum win of 12,500x the original wager. 

How To Play

As with most online game casino slots, Blazin’ Hot 7s is all about matching symbols on adjacent reels. To get started, however, you can choose between a generous betting range of $0.02 and $20 per spin, which means that this game is suitable for a variety of budgets.

To form a winning combination, you must land at least three of the same symbols on any of the 40 different paylines. The symbols must land from left to right, so the first symbol will be on the first reel from the left.

The low-value symbols will pay 0.40x for three on a payline and 4x for five across the paylines. The higher-paying symbols will pay 1x and 2.50x your wager for landing three, while a combination of five symbols pays between 5–15x the wager.

The game’s wild symbol is a 7 with the text WILD, while the game’s bonus symbol is a disco ball with the word BONUS. You’ll get a closer look at what to expect from these symbols in the sections below.


The folks over at SG Digital did a great job with the graphics in Blazin’ Hot 7s Big Bonus. They managed to combine modern and retro into a perfect balance. You’ll find the reels on what looks like an old-school disco with a purple floor and red walls. The scene is complete with white and purple strobe lights that flash across the screen. The reels are found in the middle of the room and have a lovely gold frame. You’ll find the game’s logo in red and yellow letters on top of the reels.

The symbols are based on classic fruit slot symbols, but they’ve been taken to a new, detailed, and modern level. Fruit-wise, you can expect to see an orange, plum, lemon, cherry, and watermelon on the reels. Then there’s the variety of burning 7s, the BAR symbol, and the star, which are the higher-paying symbols. As mentioned, there’s also the special disco ball bonus symbol.

All of this takes place with a surprisingly soothing soundtrack to back it up.


There are a couple of features to look forward to in this game.


The big flaming 7 with the word WILD is quite obviously the game’s wild. This can substitute for all standard symbols to help you form winning combinations. This symbol also turns into a sticky wild and stays in the same position during the free spins round.

Special Bonus Symbol

The disco ball bonus symbol triggers the free spins bonus round. Land three of these anywhere on the reels to get 8 free spins, land four to get 10 free spins, and land five to get 12 free spins.

Bonuses and Jackpots

Everyone loves slots with free spins, and Blazin’ Hot 7s Big Bonus has got you covered in this aspect. 

As mentioned, you’ll get a certain amount of free spins according to the number of bonus disco balls on the reels. At a minimum, you’re guaranteed to win a 1x multiplier for every spin in this round. Any wilds that land will turn sticky and stay in place for the remainder of the spins, vastly increasing your chances of forming a winning combination.

Then there’s the Bonus Buy. For 50x your original bet, you can buy a spin that’ll guarantee you three bonus symbols and, therefore, free spin round activation.
