Prime Zone slot review (Quickspin)


When you start the game, you are taken to a wide boulevard lined with palm trees. On the one side is the ocean, on the other high rises. A Miami Vice-themed slot was our first thought. This wouldn’t be a clone of Netent’s successful Hotline slot, would it?

With Prime Zone, Quickspin has created a retro-style slot with a few notable features, such as wilds in so-called “Prime Zones.”

Fortunately, that is not the case. Quickspin never takes the easy road by copying other providers’ slots.

Prime Zone is a real classic fruit machine, with all the well-known symbols: 7’s, liberty bells, diamonds and card symbols.

The wilds play an essential part, both during the primary game and the free spin bonus.

Prime Zone gameplay and features

Prime Zone has 10 fixed paylines and is played on 5 reels with 3 rows of symbols. So nothing new under the hot Miami sun.

The payout rate of 96.28% is pretty much standard for a new generation Quickspin slot.

The variance is medium, although you can tinker with that a bit during the bonus game.

Symbols and payouts

The symbols are noticeably large and clear. It all looks very tight, although a bit more plain compared to what we are used to from this Swedish casino game developer.

The wild symbol helps you to rake in the big money prizes in this game. Of course, it replaces all other symbols, except for the scatters, but there is more.

Every wild that is part of a winning combination increases the multiplier with +1.

Let’s say you spin five liberty bells, for example with the aid of 4 wilds. Then the total payout is multiplied x 4. Now, is that nice or what?!

Five wilds on an active payline are worth a payout of 100 x the total bet.

The premium symbols consist of red and blue 7’s, liberty bells and diamonds. Spin 5 identical ones of these on an active payline and you get between 20 x and 50 x the total bet. And that is not including possible wild multipliers.

The crazy situation can occur where it is better to spin four wilds with a blue 7 for a payout of 50 x 4 = 200 x the total bet, then five wilds that “only” pay 100 x the bet.

Free spin bonus

Spin 3 scatters on the middle reels to activate the free spin bonus.

The time has now arrived to make some crucial choices.

You receive a menu with options, whereby you have to decide with which Primes Zones you will be playing. These are certain zones on the reels where extra wilds can be placed. There are also extra multipliers that can go up to 4 x.

Choose from the following four options:

  • Option 1: extra wilds on reels 1, 2 and 3 with a 1 x multiplier (low variance)
  • Option 2: extra wilds on reels 2, 3 and 4 with a multiplier of 2 x (medium variance)
  • Option 3: extra wilds on reels 3, 4 and 5 with a multiplier of 3 x (high variance)
  • Option 4: a mystery red mode with all options open and multipliers up to 4 x (higher variance)

Options 3 and 4 have the highest risk profile. You can have bigger prizes, but there is a real chance your bonus round will get you next to nothing.

Want a bit more certainty? Choose for option 1 or 2.

The highest possible payout is 2,685 x the total bet, using option 4.

If you opt for option 1, you can win a maximum of 1,000 x the bet.

Our verdict on the Prime Zone video slot?

Prime Zone is a top-notch video slot, just like almost all Quickspin slots. Is it good enough to be in our top 10 of Quickspin slots?

Not entirely, but then that is a very high bar.

We would like to have seen a bit more depth in the primary game, (perhaps a mystery wild bonus), but we did have a lot of fun, nonetheless.

This slot is suitable for those times you want to play a long time with your money, with relatively speaking a lot of free spin bonus features.

3.7 out of 5 stars.
