Jackpot Giant Pros and Cons

Reviewed by Paul Stone
Published: September 2018

Pros

• The progressive jackpot is the real draw, fed across Playtech’s network, it has paid out as much as roughly £9.4 million, and landing Wilds along the middle row at £4 a spin is what unlocks it.
• The Giant Bonus is a genuinely fun pick-round: choose up to six erupting volcanoes for cash prizes, a change of pace from spinning that breaks up a session nicely.
• Even away from the jackpot the ceiling is high, a screen full of Wilds at under £4 a spin pays 50,000x your total bet, and at any non-£4 level the Wilds-across-the-middle-row trigger still awards 1,000x.
• It plays from just 50p a spin with a high base-game hit frequency, so the cartoon Stone Age world stays lively between features rather than sitting dead.

Cons

• The 94.22% RTP is clearly below the modern average, typical for jackpot slots, because a slice of every bet funds the progressive, but a real cost over a long session.
• The top jackpot is effectively gated: you only qualify for the progressive by betting exactly £4 per spin, so casual low-stakes players are chasing the 1,000x consolation, not the millions.
• Feature variety is thin by modern standards, stacked and expanding Wilds, the volcano pick and the jackpot trigger are the whole offering, with no cascades, multipliers ladders or modern extras.
• The visuals and soundtrack, bright as they are, show their 2014 age next to current Playtech releases.

How Jackpot Giant Works

Jackpot Giant runs on a 5-reel, 3-row grid with 50 fixed paylines, paying left to right from the leftmost reel, from 50p a spin up to the £4 level that qualifies for the progressive. The friendly Stone Age giant is the centrepiece, and the game leans on stacked and expanding Wilds to build wins. There is no cascade or ways-to-win gimmick here, it is a straightforward payline slot whose interest comes from the volcano Giant Bonus and, above all, the network jackpot. The single most important rule to understand is the bet level: only a £4 stake puts the true progressive in play.

Symbols and Paytable

The giant and the themed Stone Age icons sit at the top of the paytable, with the Wild the symbol that matters most, it stacks and expands to fill positions and, crucially, lines up across the middle row to trigger the jackpot mechanic. A full screen of Wilds is the route to the 50,000x total-bet max win when you are betting below the £4 jackpot threshold. Lower symbols fill out the frequent small wins that keep the high hit-rate base game ticking.

The Progressive Jackpot

This is what Jackpot Giant is built around. The jackpot is a Playtech network progressive, pooled across many casinos, and it has historically climbed into the millions, with a record payout reported at roughly £9.4 million. To win it you need Wilds landing across the middle row while betting the maximum £4 per spin. Land that same Wild line at any other stake and you do not miss out entirely: you collect 1,000x your total bet instead. That £4 gate is the defining tension of the game, the difference between a life-changing prize and a still-substantial consolation comes down to your bet size, which is the first thing any serious Jackpot Giant player needs to weigh up.

The Giant Bonus Feature

The Giant Bonus is the game’s pick-style round: you are presented with erupting volcanoes and choose up to six of them, each revealing a cash prize, before the round ends. It is simple, but it lands at a satisfying rhythm and gives you a guaranteed return away from the paylines. After the relentless build toward the jackpot, the volcano pick is the slot’s moment of light relief, and a reliable source of mid-sized wins that pad out a session between bigger hits.

What is the RTP of Jackpot Giant?

Jackpot Giant has an RTP of 94.22%, below the roughly 96% modern average. That is typical for progressive jackpot slots, where a portion of every bet funds the jackpot pool, worth factoring in before you play.

What is the max win on Jackpot Giant?

Excluding the progressive jackpot, the maximum win is 50,000x your total bet, achieved with a full screen of Wilds when betting under £4 a spin. The progressive jackpot itself is separate and has historically paid into the millions, with a reported record of around £9.4 million.

How do you win the Jackpot Giant progressive jackpot?

You win the progressive by landing Wilds across the middle row while betting the maximum £4 per spin. Land that same Wild line at any other bet level and you win 1,000x your total bet instead of the jackpot, so the £4 stake is essential to qualify for the top prize.

Does Jackpot Giant have free spins?

Jackpot Giant’s headline features are the progressive jackpot, the stacked and expanding Wilds and the volcano Giant Bonus pick-round, rather than a conventional free spins round. Some listings tag it with free spins, but in practice the Giant Bonus and the jackpot mechanic are the features that define play.

How does the Giant Bonus work?

The Giant Bonus is a pick-style feature where you choose up to six erupting volcanoes, each revealing a cash prize. It gives a guaranteed return away from the paylines and breaks up the base game between bigger jackpot-chasing spins.

Who made Jackpot Giant?

Jackpot Giant was developed by Playtech and released on 20 December 2014. Playtech, founded in Estonia in 1999, is one of the largest gaming-software suppliers in the world and holds a UK Gambling Commission licence for its UK-facing content.

Is Jackpot Giant worth playing?

If you specifically want a shot at a large network jackpot from a low stake, it remains a solid, friendly choice with a fun volcano bonus. If you want a high RTP, rich features or modern mechanics, newer slots will serve you better, and remember only a £4 bet puts the full jackpot in play.

Our Verdict on Jackpot Giant

Jackpot Giant is a jackpot slot, and judged on that it does its job: the Playtech network progressive has paid into the millions, the volcano Giant Bonus is good fun, and a 50p entry point keeps it accessible. The catch is the trade-offs jackpot slots always make, a below-par 94.22% RTP, thin feature variety, and a top prize effectively locked behind a £4 bet, leaving low-stakes players chasing the 1,000x consolation. It is for players who specifically want a shot at a big network jackpot and enjoy a light, cartoonish Stone Age theme, not for anyone after deep features or strong base-game value. If you like slots like Jackpot Giant, Playtech’s Age of the Gods range offers the same jackpot-chasing appeal with more modern feature design.
