Cash Eruption MegaJackpots Slot Review
A temple built to house a jackpot: Cash Eruption MegaJackpots charges you for its progressive on every single spin, and that toll is the whole story of this game. Two percent of the return goes into a prize pool almost nobody will ever touch, which is why the total sits at 91%, or 89% once the jackpot contribution is stripped out. IGT makes that an easier pill to swallow here than most, wrapping the pill in firelit stone, a 5×3 grid, 20 fixed paylines and a 5,000x fixed ladder on the side.
The MegaJackpots progressive seeds at half a million pounds and grows from there. Stablemates worth knowing include Cash Eruption, Cleopatra and Triple Cash Eruption The Western. The original eruption built its name on a long, glossy wait between fireball rounds, and this version keeps the wait while adding a far bigger prize to chase.
Base Game & Features
The reels sit inside that Aztec-stamped gold frame on a 5×3 grid, with betting fixed at 20 paylines. Stakes are set through the total bet menu: pick a coin value and a total bet, and the 20 lines come as part of the package. There’s no way to play fewer of them.
The menu itself is straightforward. A cog icon or the total bet readout opens it, the coin count and coin value are displayed alongside your total, and a tap of OK confirms everything. On desktop, plus and minus buttons step the stake up and down instead.
Auto Spin handles the repetitive part where the jurisdiction allows it. You choose the number of spins, and where available a loss limit and an optional single win limit. It stops on any bonus trigger, on a drained balance, or when a limit is reached.
The wild substitutes for every paying symbol, with a single exception: it doesn’t stand in for the Red 7 in a pattern win. Everything else on the reels is classic fruit-and-sevens material, dressed up in glossy 3D.
The paytable is a modest one, and it’s honest about being so:
- Red 7 (red ribbon): 25.00 for five, 5.00 for four, 1.00 for three
- Blue 7: 20.00 for five, 3.00 for four, 1.00 for three
- Bell and Watermelon: 10.00 for five, 2.50 for four, 1.00 for three
- Grapes: 7.50 for five, 2.00 for four, 0.50 for three
- Plum and Orange: 5.00 for five, 1.50 for four, 0.50 for three
- Lemon and Cherry: 4.00 for five, 1.00 for four, 0.50 for three
- Bonus scatter: 200.00 for five, 30.00 for four, 4.00 for three, multiplied by the total bet
Three symbols from the bottom tier of that list returns half your coin value, so the fruit is there to keep the reels moving rather than to pay for the session. The real money sits in the scatters, the pattern and the fireballs. Wins are shown at the current bet, so everything scales with your stake.
Note the shape of that list, too. The Red 7 pays two and a half times what the Lemon does for a five-of-a-kind, but the gap narrows to nothing at three-of-a-kind, where every top-tier symbol pays 1.00 and every bottom-tier one pays 0.50. The paytable is flat at the bottom and only spreads at the top.
Pattern Feature
There’s one unusual line-based extra. Fill every position on reel 1 with the Red 7 symbol and cover the other four reels entirely with wilds, and you’ve earned a pattern win. The wild doesn’t count as a Red 7 for this, and line wins aren’t paid on top of it.
It’s a long shot by design. Fourteen positions all landing correctly at once doesn’t come round often, but it’s the one base-game moment that pays outside the ordinary paytable, and it gives the wild something to do beyond filling gaps.
Cash Eruption MegaJackpots Bonuses & Jackpots
Free Spins
Three Bonus symbols trigger the free spins round. During it, reels link up and spin together, and that’s where the features start feeding each other: a Fireball landing on a linked reel in the bonus triggers the Cash Eruption Bonus directly. Scatter wins from the trigger are multiplied by the total bet.
At the maximum of five scatters, that’s 200x the total bet before a single free spin plays out. The linked-reel structure is the quiet point of the round: it concentrates fireballs, which is exactly the symbol you want concentrated.
MegaJackpots Bonus Game
The headline event is a single spin on its own set of reels. Five MegaJackpots symbols collected in the bonus meter earn that spin, and a Jumbo MegaJackpots symbol landing in the bonus earns it too. These reels are different from the base game’s, carrying Multiplier and Wild symbols instead of fruit.
Everything in the middle row is awarded, and revealed multipliers are added together. If a MegaJackpots symbol shows up anywhere in that row, the progressive is yours. Only one progressive is paid per award.
It’s a clean decider. One spin, one row, and the biggest prize in the game either lands or it doesn’t, with no second attempt and nothing to carry over.
Every bet offers a chance at the progressive, and the odds are proportional to the amount staked: a player at 0.20 per spin has exactly twice the chance of a player at 0.10, with the same expected return for both. Bigger bets buy better odds, not a better game.
Cash Eruption Bonus
Six or more Fireball scatter symbols anywhere in the base game trigger the Cash Eruption Bonus, the hold-style round the series is built around. Fireballs carry cash values and jackpot labels on their faces, from small amounts up to the fixed ladder’s rungs.
A Fireball on the linked reels during the bonus triggers the round again, so the free spins and the eruption feed each other rather than taking turns. The two features sharing a symbol is what gives this game its shape.
The fixed ladder alongside the reels pays, as multiples of the bet:
- Grand: 5,000x the bet
- Major: 100x the bet
- Minor: 25x the bet
- Mini: 5x the bet
The Grand rung at 5,000x the bet is the fixed ceiling of the game, and it sits inside the fireball round rather than behind the progressive gate. Between that and the progressive, two different bonus routes lead to two different top prizes.
Our Honest Verdict
Overall Rating: 6.9/10
This is a long sit in a beautiful temple, and the reason somebody chooses it over the ordinary Cash Eruption is the half-million-pound progressive ticking away above the reels. The firelight is gorgeous and the reels are quiet, and the jackpot is the thing that makes the quiet worth sitting through.
Its best trick is the two-route prize structure: the fireball round pays up to 5,000x the bet on its own ladder, so there’s a life-changing ceiling to chase that doesn’t depend on the progressive landing. Its worst is that the jackpot toll quietly taxes every spin, and the flat fruit paytable gives almost nothing back in the meantime.
Jackpot hunters and fans of the series will feel right at home in the firelight, and a slot that pays for patience with a half-million-pound ceiling is a rare thing. Anyone who wants regular wins to carry a session will find the temple doors stay shut for long stretches, and the prize they’re paying towards never opens for them.
