IGT’s MegaJackpots slots are somewhat famous at this point. While they don’t quite compete with the Mega Fortunes and Mega Moolahs of the gaming world, they do supply jackpots in excess of a cool one million. They also tend to hit more often than the aforementioned progressives. Isle O’ Plenty is sure to be welcomed by gamers who have enjoyed the company’s previous MegaJackpots titles (Cleopatra and Siberian Storm), but is there anything new here? Ahead of its release (on February 25), we took the game to task, asking the hard questions and investigating the gameplay to see if this one’s worth crowing about.

Greed is Good

Gamers play progressives for one reason: they want to be in with a shout of winning the biggest jackpots. With Gordon Gekko’s famous mantra embedded in their heads, they play the reels hoping to hit pay dirt; and who can blame them? Who doesn’t like the idea of winning a cool million from just a few spins of the reels?

To play Isle O’ Plenty, you’ll have to stake coins that range between 0.60 and 1,800. The total coins permissible? 60. This game should consequently appeal mostly to high rollers. On the grid, you’ll find icons such as leprechauns, harps, violins, pots of gold, rainbows, Celtic trees and flowers. Each has a different coloured background, making it easy to distinguish between the icons.

How toBreak the Bank

Hitting the MegaJackpots progressive prize is deceptively simple – in theory, anyway. You simply need to hit four MegaJackpots symbols in the central column in the base game or bonus feature. You can also win a behind-the-scenes second chance if you’re waiting on one last symbol.

Want Some Free Spins?

Not all slot games grant free spins, but the ones that neglect this feature do so at their peril, not least because gamers have come to expect them. Thankfully, Isle O’ Plenty accept that it’d be remiss to forego free spins. Thus, players can unlock up to 24 free spins by hitting lighthouse bonus symbols. Get six free spins for two, a dozen for three and 24 for four. The bonus can also re-trigger, meaning – in theory at least – there’s a possibility of activating up to 240 free spins. You’d have to be damn lucky to end up with anywhere near that figure, though.

During free spins, a touch of leprechaun magic may cause you to hit some big wins. This is because the bearded leprechaun enchants the top row on every single free spin, rewarding you with one or more wild icons. There’s also a chance of a MegaJackpots symbol cropping up during free spins, further increasing your chances of winning the progressive.

A Wild Rush

The Wild Rush feature is activated with the appearance of a solitary wild symbol. However, the wild can also stack up, greatly enhancing your chances of forming winning combinations. Wild symbols domino downwards to fill entire reels, and the feature applies both in the base game and during the free spins bonus feature.

The inclusion of stacked wilds means you can have plenty of fun and win some nice paydays, even if you don’t hit the coveted progressive jackpot.

Irish Gold

MegaJackpots Isle O’ Plenty is an ultimately satisfying medium-variance progressive. If you enjoyed IGT’s previous MegaJackpots games, there’s no reason to suppose you won’t like this one. The game should also appeal to fans of the classic Rainbow Riches game, as well as devotees of NetEnt’s Mega Fortune.

There’s a certain whimsical charm about Isle O’ Plenty, playing as it does on Irish folklore; you can certainly have a laugh about the symbols as you spin the reels. An abundance of features, including free spins bonuses and additional wilds during free spins, also enhances the overall gameplay. We look forward to playing this one for real!
