Jackpot Giant slot

What the Jackpot Giant slot is

Jackpot Giant comes from Playtech, founded in 1999 in Tartu, Estonia, and now headquartered on the Isle of Man and listed on the London Stock Exchange. Playtech is best known for its jackpot games, including the Age of the Gods network, and Jackpot Giant, released in 2014, is one of its longer-running stand-alone progressives. The theme is a cartoon giant in a prehistoric landscape of volcanoes, written for adult players and simple to read.

The game belongs to the progressive jackpot slot machines family. That label tells you more about its maths than any graphic: a slice of every stake is set aside for one large prize, so the ordinary paytable has less to work with. Understanding that trade-off is the key to deciding whether the game suits you.

How the Jackpot Giant slot machine works

1. Choose your stake. All 50 paylines are fixed, so the stake is divided across them.
2. Spin. The random number generator fixes the outcome, including any jackpot win, before the reels move.
3. Line wins are paid for matching symbols from the leftmost reel along any of the 50 lines.
4. A contribution from your stake is added to the progressive jackpot pool.
5. If the Volcano bonus symbols land in the required positions, the pick feature starts.
6. If the jackpot combination lands under the qualifying conditions, the jackpot is paid; otherwise the spin ends and the next can start after 2.5 seconds.

Fifty lines on a 15-position grid means many overlapping routes, so small wins are frequent. Most are smaller than the stake: on a 50p spin, a line that pays 10p still leaves you 40p down. UK games aren't allowed to celebrate such returns as wins, a rule in force since 31 October 2021.

How the Jackpot Giant progressive jackpot works

Every stake on the game adds a small amount to the jackpot pool, which starts from a seed value and grows until someone wins it. Our page on how jackpots are funded shows the arithmetic in detail. The share of each stake that goes to the jackpot is set by Playtech and shown, where published, in the game's help screen.

Reference listings describe the jackpot as won by landing five of the giant wild symbols on payline 1, the middle row, and say a lower stake pays a fixed prize instead of the full progressive. We couldn't confirm the qualifying stake from Playtech directly, so check the help screen before you play: it states the exact rule for the version your casino runs. If the qualifying stake is above your legal limit (£2 a spin for 18 to 24-year-olds, £5 for those aged 25 and over), you couldn't qualify for the full jackpot at that casino.

A jackpot that hasn't been won for a long time isn't 'due'. The chance of winning is set by the game's maths and is the same on every qualifying spin, whatever the pool size.

Jackpot Giant bonus: the Volcano pick feature

The game's main feature is a pick bonus. Reference listings say it starts when Volcano bonus symbols land on reels 1 and 5 on the same base-game spin. You then pick three of six volcanoes. Each hides a cash prize, an Extra Pick that lets you choose a fourth volcano, or Win 'Em All, which pays every prize on the board.

Worked example

Say you stake 50p and the six volcanoes hold prizes of 2x, 3x, 5x, 8x, 10x and 20x the stake. You pick three and reveal 3x, Extra Pick and 8x, then use the extra pick to reveal 10x. You win 3 + 8 + 10 = 21x, or £10.50. Had one of your picks been Win 'Em All, you would have taken the full 48x, £24. The prize values here are invented to show the mechanics; the real ones are in the help screen.

There is no free spins round in published descriptions of Jackpot Giant. The Volcano pick and the jackpot are the two features.

Jackpot Giant RTP and what it costs to play

The listed RTP is 94.22%. Over millions of spins, the game returns about £94.22 of every £100 staked, a margin of £5.78. That figure includes the jackpot, which is won rarely, so the return from ordinary play during a typical session is lower still. This is common to progressives, and it is the price of the large top prize; see are high RTP slots better for how to weigh it.

Playtech doesn't give a volatility rating in our sources, so we don't state one. Frequent small line wins smooth the experience, but the jackpot share means the long-run cost is higher than for a 96% game: £5.78 per £100 here against about £4 at 96%.

Jackpot Giant max win and jackpot odds

Because the top prize is progressive, Jackpot Giant has no fixed max win multiple. The jackpot's value on any given day is shown on the game's lobby tile or in the game itself. We don't quote jackpot sizes, past wins or odds, because they change constantly and Playtech doesn't publish the odds of the jackpot.

What we can say is how rare such prizes are by design. A jackpot paid from a few per cent of all stakes, and large enough to be worth chasing, has to be very unlikely on any single spin. Our page on the odds of winning a slot machine jackpot explains the maths, and what happens when a slot jackpot is won covers payment.

Is the Jackpot Giant slot worth it?

Jackpot Giant suits adults who understand that they are paying a little more per spin for a very small chance at a large prize. If you'd rather keep the long-run cost down, a high RTP slot machine is the better fit.

Jackpot Giant myths: big pools and due jackpots

• "A big pool means it's about to drop." A pure progressive has no due date; the odds per qualifying spin don't change with the pool.
• "Four wilds on the line was nearly the jackpot." It was a losing outcome; read about near misses.
• "Always bet max on jackpot slots." Only if the rules require it to qualify and it fits your budget and legal limit; see should you bet max.
• "Someone just won, so it won't pay again for months." Each spin is independent; the next jackpot could come at any time or not for a long while.
