Jackpot Raiders slot review

Jackpot Raiders slot at a glance

Jackpot Raiders comes from Yggdrasil, the Malta and Kraków-based studio behind Valley of the Gods and the Vikings series. Released in May 2019, it pairs a standard 5×3, 20-line grid with a web of collectable symbols that lead into its bonuses.

Low volatility combined with a jackpot element is an unusual mix among the slots we review, and it sets the game apart from most treasure-hunt titles.

Low volatility explained: a £20 Jackpot Raiders session

Low volatility means the game returns money in smaller, more frequent amounts rather than saving it for rare big hits. A budget tends to last longer and fall more gradually, though the house edge still means losses are the expected result over time.

The average cost is 74p at every stake, because it’s 3.7% of £20. With small wins frequently returned and re-staked, real sessions often last longer than the raw spin count suggests, which also means more total money staked. Keep the budget fixed rather than letting play run on.

How the features work: compasses, maps, gems and relics

Four kinds of collectable drive the bonuses. Each one leads somewhere different.

Compass scatters and maps

Landing three or more compass scatters sends you either to the Treasure Hunt bonus or to extra spins. Maps give a slower route: collect five identical maps and you also get extra spins. That gives the base game a sense of progress even on spins that don’t pay.

Treasure Hunt and Sunken City

Treasure Hunt is a pick-style bonus, where choices on screen reveal rewards. Collecting five relics inside it triggers Sunken City extra spins, where every line win is multiplied by 10x. That multiplier makes it the strongest of the bonus rounds.

The Jackpot Raiders jackpots: what’s confirmed

The jackpots are won during extra spins. Gems are collected as the spins play out, and five gems of the same colour win one of the jackpots. The 4,110× maximum win figure excludes jackpots, so a jackpot sits on top of the regular cap.

Our verified data doesn’t include how many jackpot tiers there are, what they’re worth, or whether they’re fixed or progressive, so we don’t state those details. The game’s paytable is the place to check. If you’re interested in networked prizes, our progressive jackpot entry and jackpot slots guide explain how they differ from fixed ones.

Jackpots are rare by design. Treat any jackpot as a remote bonus to normal play, not a reason to stake more or play for longer.

Jackpot Raiders RTP and cost per hour

The published RTP is 96.3%, a house edge of 3.7%. Your average cost is stake × 3.7%. The table assumes an illustrative 450 spins an hour; the UK’s 2.5-second minimum spin time allows up to 1,440.

Low volatility means a single session will track these averages more closely than a high-volatility game would, though it can still finish well above or below them.

Jackpot Raiders max win: 4,110× in pounds

Leaving jackpots aside, the top regular win is 4,110× your stake. That’s £411 at 10p, £2,055 at 50p and £4,110 at £1. At £2, the cap for players aged 18 to 24, it’s £8,220, and at the £5 cap for those aged 25 and over it’s £20,550.

A moderate ceiling like this is typical of low-volatility design: the game spreads its returns across many smaller wins rather than packing them into a rare giant result.

Before you play Jackpot Raiders: a quick checklist

1. Open the game in your casino app and check the RTP in its rules screen.
2. Read the paytable for the jackpot details and how maps, gems and relics are collected.
3. Set a session budget and a reality check reminder in your account.
4. Choose a stake that fits the budget; 10p gives 200 spins from £20.
5. Stop at your limit, even if a collection feels close to completing.

That last point matters on collection games. Partly filled meters can create a feeling that the next spin is due to finish them, but every spin is random and independent of the last.

Playing Jackpot Raiders on iPhone and Android

Jackpot Raiders is an HTML5 slot that loads inside casino apps and mobile browsers. The 5×3 grid is easy to read on a phone; keeping track of maps and gems adds a little more to follow.

• Whether it plays in portrait or landscape depends on the app and game build.
• Pick bonuses like Treasure Hunt need accurate taps, which is easier on a bigger screen.
• Our pages on iPhone casino apps and Google Pixel cover setting up on each platform.

UK rules for Jackpot Raiders in casino apps

The British version follows the Gambling Commission’s rules for online slots, several of which came from the government’s High stakes white paper (opens in a new tab) on gambling reform.

The stake limits are set out in the Commission’s online slots stake limit guidance (opens in a new tab), and the requirement for clear game rules is in RTS 3 (opens in a new tab). Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players. Our white paper explainer and slot stake limits page cover the background.

Jackpot Raiders vs other Yggdrasil and low-volatility slots

These games share either the studio or the gentle volatility profile. All figures are verified specifications.

Vikings Go Wild shares the same RTP with a slightly livelier profile, and Holmes & the Stolen Stones has the highest RTP of the Yggdrasil group. For low volatility from another studio, Starburst and Blood Suckers are the best-known options.

Yggdrasil was founded in 2013, is led by chief executive James Curwen and holds a Great Britain licence among others. Its catalogue runs to about 190 games.

Jackpot Raiders slot review verdict

Jackpot Raiders is a well-built low-volatility slot with more structure than most: compasses, maps, gems and relics give each session a sense of progress. The 96.3% RTP is fair, and Sunken City’s 10x line wins add real punch. The main gap is that the jackpot details aren’t in our verified data, so read the paytable before you start.
