Extreme 7 review: introduction

Extreme 7 joins the ranks of Slots Temple free slots and is one of the classiest-looking online slots you will ever lay eyes on. Don’t expect too many frills in terms of gameplay, but Extreme 7 offers classic fruit machine-style gameplay at its finest. The slot is accessible and its core mechanics are extremely solid.

As a fruit machine, all the symbols are immediately familiar. Diamonds lead the way payout-wise, followed by a pair of lucky 7s and two sets of bar symbols. There aren’t any wilds or scatter symbols in this slot - while a little unusual, this makes the gameplay more straightforward and keeps things pure. 

There are a mere five paylines, but this is not a major area of concern given the shrunken size of the grid. Extreme 7 is smaller than many other online slots at just 3x3. Autoplay is available, winnings pay from the left, and you can even opt for turbo rounds.

You can play this and other Green Jade slots online right here at Slots Temple.

Theme, graphics & design

Extreme 7 might not be overflowing with special features and design flourishes, but it makes up for this with a heady injection of style. This is a classic fruit machine that has been given a sophisticated high-gloss makeover that shines through at every opportunity. The reels are massive but feel truly premium. They are trimmed with gold that glitters against a deep red background.

Reds, golds and whites are the colours of choice, and this is more than enough to create an atmosphere of high luxury. The slot logo and paytable, which is displayed next to the reels at all times, have golden outlines. The symbols are polished and veritably shine. They are nice and chunky and pop against the white reels. Extreme 7 is simple, but Green Jade Games has worked extra-hard to give it classy visuals.

The music is more of a mixed bag. Although we enjoyed the music that accompanies the spinning reels, this is a slot that lends itself perfectly to a more extended soundtrack. A laidback lounge tune or something jazzy would have been the perfect fit for the high-end visuals, so it is a shame that Green Jade Games didn’t go down this route.

Extreme 7 RTP and variance

Although no information about variance has been released, we do have some specific details about Extreme 7. Its RTP is a healthy 96.1 per cent and the top prize is 600x. This is not the most spectacular win that you will encounter, but it is more than adequate for a slot of this kind.

How to play Extreme 7

Extreme 7’s appeal lies in its sheer simplicity and accessibility, so it should come as no surprise to learn that it has virtually no learning curve. These tips should be all you need for an enjoyable experience:

  1. When the slot has loaded, look for the sound button. You can adjust the music and reel effect levels.
  2. Have a quick look through the paytable next. There are no complex menu systems to navigate here, as the payable is small enough to be displayed to the left of the reels!
  3. The small question mark icon opens the game rules, where you can also read about the paylines.
  4. The bet controls are just as simple: the + and - keys will raise and lower your stake.
  5. Autoplay and spin are the two central buttons. Use autoplay if you want to pre-programme a set of spins with loss and win limits.
  6. Set a budget that is within your means and always keep responsible gambling in mind.
  7. Hit the spin button to set the reels in motion.

Bet & win sizes

Extreme 7 has a big bet range, as players can start low with just 0.25 or go as high as 500. It is easy to adjust your stake sizes using the bet controls; alternatively, you can tap the max bet button if you want to jump straight to the highest possible wager.

The top single line win on Extreme 7 is 600x, which is awarded for landing three triple diamond symbols. The full paytable for three matching symbols is as follows:

  • Triple diamonds = 600x
  • Single diamonds = 200x
  • Double lucky 7s = 36x
  • Single lucky 7s = 32x
  • Triple bars = 24x
  • Single bars = 20x

Extreme 7’s five paylines might seem disappointing at first glance; however, this slot is only 3x3, so five paylines are enough to keep gameplay ticking along nicely.

Extreme 7 bonus features

This is the area in which Extreme 7 lets itself down. There are no bonus features to be found - not even special symbols such as wilds or scatters. While we appreciate that this is a deliberate design choice and certainly keeps the gameplay feeling pure and straightforward, we think that the addition of at least a wild or scatter would have improved the game.

Final thoughts

Extreme 7 is an online slot that purists will love. Its gameplay is simple, exciting, and reminiscent of a much simpler era. 

Although we would have preferred to see at least one bonus feature, it is hard to argue with Green Jade Games and its determination to make a truly classic slot. Extreme 7 is sophisticated, stylish, and sometimes outright luxurious!

This might not be the place to look if you are someone who seeks out dramatic bonus features, but it is a great example of pure gameplay. If you enjoy this kind of classically styled slot, we think you will also love the Extreme Fruits 20 slot.
