Testing Notes: Here’s What Happened When We Played Primal Hunter Gigablox

IMPORTANT: To give you an accurate assessment of the games we review our writers play 200 spins. Whilst this is a useful tool to help us review games and to give an example of what might happen when you play, keep in mind that 200 spins is only a very small sample and cannot be used to accurately predict what might happen over another 200 spins. The outcome of all slots play is always random.

Boom Or Bust? Our Session By The Numbers

I played 200 spins on Primal Hunter Gigablox on Reel Play’s test server prior to release to test the game. This is what happened.

  • Stake Size: €1
  • Start balance: €11,000
  • End balance: €10,897.07
  • Hit Rate: 19.5% (39 winning spins in 200)
  • Biggest Win: 23.37x
  • Free Spins Round: 0

Primal Hunter Gigablox is billed as a medium-high variance slot but it felt more like a high variance in every way over this short test session. The hit rate was just 19.5% which is low, even for a volatile game, and most wins came in at 5x or less. There was one good moment where a 23.37x win came from a run of 3 cascades culminating in 15 10s across the reels, shown in the screenshot.

I never unlocked the free spins. It can take 250 or more in high variance slots so it’s not totally unusual, but without much else going on in the base game it made Primal Hunter feel like a bit of a slog. The dramatic shaking and fire that highlights the gigablox reels is fun to start, but the novelty can wear off quite quickly if you don’t land some good wins. In short, whilst a great looking game, this is definitely a slot for high-risk fans who have the patience to chase down the big moments.

  • Gigablox guaranteed on EVERY spin
  • Superb production with great visuals and audio

"This simple slot is built for high risk slots fans with an epic production to match the dramatic gameplay. Just a shame the max win isn't higher!"

Overall Score: 8.0

Theme & Design

Our Score 9

Dramatic Primal Atmosphere For Big Win Hunters!

ReelPlay have created an epic-looking game invoking a prehistoric age of volcanic mountains and lush jungles populated by dinosaurs including T-Rexs and pterodactyls. Center stage is a giant reel set built in stone and lit up by flaming torches that rattles around as the reels spin, spitting fire in the lines around the rows that combine to form gigablox on each spin. It’s a dramatic scene and the artwork is really well crafted, backed by a tribal drumbeat soundtrack that adds to the atmosphere.

RTP and Variance

Our Score 8

What is RTP?

RTP (Return to Player) refers to the amount a game will pay out in cash prizes expressed as a percentage of all the money wagered on that game. For example, a 96% RTP means a game will pay out £96 for every £100 wagered. This is an average number and will vary from one session to the next.  Read more here.

What is Variance?

Variance refers to how far a game will deviate from its RTP over time. High variance games deviate a lot and produce uneven win distributions and unexpected windfalls. Low variance games provide a more stable and even distribution of wins. Read more here.

Primal Hunter Gigablox runs at an optimum return to player of 96%. However, there are also settings of 94%, 90.5% and 86%. Check the RTP wherever you play by hitting the ‘?’ to the right of the reels then scrolling though until you see Return To Player. To get the best return I recommend playing at Casumo or Barz Casino (White Hat Gaming) both of which consistently run games at their highest RTP.

 This is also a medium-high variance slot so it will be a volatile game with an uneven win distribution and where the right combination of free spins and multipliers can really make the game go off.

Maximum Win

Our Score 7

What Is Maximum Win?

Maximum win refers to the maximum amount a player can win from one spin. It is expressed as a multiple of the stake. For example, where the maximum win is 100,000x, from a £1 stake, the maximum win would be £100,000.  

The game has a max win of 7,595x which isn’t bad but doesn’t quite scale the heights that you might expect from a game that is built around the idea of epic-size apex predators. If you want to chase down higher value payouts then I recommend taking a look at the games in our list of highest paying slots.

Symbols and Paytable

Our Score 8

This is a 6 reel and 4 row slot with 40 active paylines on every spin. You’ll need to land 3 or more identical symbols across a line from left to right, starting at the left most reel, to trigger a win.

To help you, the game uses ReelPlay’s Gigablox mechanic where reels combine on EVERY spin to create larger symbols of 2×2 or 4×4 in size. These can be ANY symbol from the paytable including wilds and scatters.

Primal Hunter Gigablox Paytable
The paytable with 3.75x for 6 T-Rex

There are 10 pay symbols in the paytable. These are the 6 cards – 9, 10, Jack, Queen, King and Ace – valued at from 0.05x for 3 9s up to 1.5x for 6 Aces. The premiums are the 4 animals including the pterodactyl, sabre-toothed tiger and the T-Rex. These are valued at from 0.175x for 3 pterodactyls up to 3.75x for 6 T-Rexs.

There is also a pre-historic hunter character, a bearded man, who represents the Wild. This will substitute for all pay symbols to complete pay lines and has its own value at 0.5x, 1x, 2.5x or 10x for 3, 4, 5 or 6 on a payline.

Features and Gameplay

Our Score 8

Primal Hunter Gigablox is a very simple slot using classic cascades, win multipliers and free spins. Here is how it works.

Cascading Wins 

In both base game and free spins round winning symbols are removed from the reels after each win. Remaining symbols drop down to fill the spaces and new ones drop from above to replace those ones. If more wins occur then the process repeats until no more wins are formed.

Free Spins and Progressive Multipliers

This is where you really want to get to in this game. Free spins are triggered by landing 5 or more scatters on one spin. Scatters are represented by the skull symbol.

It’s simple. You get 2 free spins for every scatter that lands on the triggering spin. And during the round for each win cascade a progressive multiplier starting at 1x increases by 1x. There is no limit to the size of this multiplier which does NOT re-set between spins and is applied to ALL wins throughout the round.

Finally, you can extend the free spins round by landing another 5 or more scatters on one spin. This time you get 1 more spin per scatter.

The Final Verdict

ReelPlay have created a really good slot for fans of high-risk gameplay. The production is excellent with eye-catching visuals and sounds, and the no-nonsense features, stripped back to the bare bones of free spins and progressive multipliers will appeal to anyone who likes to just gun for glory without the complication of too many enhancements. The only minor quibble is that the max win was not set higher than 7,595x.

Useful Tips When Playing Primal Hunter Gigablox

Remember, online slots are games of chance, there is NO strategy that can improve your odds of winning. However, reading our review and following these tips will help you get the most out of your time playing this slot game.

1. Look For Skull Scatters At All Times

The secret to winning big here is landing 5 or more scatters to trigger the free spins round. That is where the best stuff happens with progressive multipliers to boost your wins.

2. Find A Casino With The Max RTP

To give yourself the best chance of winning make sure you play at the optimum RTP of 96%. You can do this by checking the RTP on the game info screen once you load up the slot. If it’s less than 96%, find another casino!

3. Play At A Low Stake

This is a medium-high variance slot so it can be a tough play and burn your balance fast. Choose a low stake – the minimum is 40p – to absorb those dry spells whilst you chase down the big wins.

4. Play At A Licensed UK Slot Site

Make sure you always play slots at licensed sites like the ones on this page where the games have been audited for fairness and security.
