Loose Cannon slot from Microgaming

Loose Cannon slot from Microgaming
Every self-respecting online slot developer should have at least 1 pirate-themed slot in their portfolio. And every regular player should have at least 1 pirate-themed slot in his TOP 10 favourite online games.

After Microgaming released Cannonball Bay in 2013, they took it up a notch just a year later - in 2014, with this cartoonish take on pirates - Loose Cannon slot machine. All the typical ‘arr’- elements are included: One-eyed Captain, Voluptuous Pirate Girl, Riches chest, Treasure Map, and of course the Loose Cannon. Add a Wild Pirate Ship, Mischievous Monkey, and Compass Scatter, and you’re ready to set sail. The Wild landing on reel 3 automatically means it will expand to a full reel, while it can randomly shoot left and right, turning adjacent symbols Wild as well. We advise you to try the Thunderstruck Wild Lightning slot by Microgaming for free.

During Free Spins, wins are paid both ways, which will never hurt anybody. The pirate action of this Medium Volatility game takes place on a 5x3 grid, crossed by 243 win ways, and with its RTP of 96.13% and a max payout of 75 000, Loose Cannon is surely worth a spin or two.

Check it out for free in the DEMO version on the ‘arr’ page. No registration is required.

Personal testers’ opinion

This pirate-themed online slot has decent (not superb) graphics and a festive pirate-polka soundtrack. However, even with the stacked Wilds showing themselves very often and shooting/rendering additional Wilds, the game produces only small payouts, which are not enough to give positive recommendations to the bonus hunters. So we leave neutral suggestions for using the Loose Cannon slot machine to fulfill the wagering requirements - 5.1 points out of 10. 28 out of 100 spins will award you with wins in the base game, though they can be smaller than your bet. This is a disappointing figure, as is the small percentage of the prize pool put aside for payments in the Free Spins - only 26%. However, these bonus spins are launched reasonably frequently - statistically, after every 113th spin, and the best part in them is the win both ways feature. The slot comes with a very tempting (default) maximum potential - which by our calculation is equal to 2000x the total bet, but in practice, what the game actually delivers is not more than 300- 400x the total bet. Our team reported the biggest win of 58x in the regular spins during the tests and 29x on average during Free Spins. In short: you can play here with real money, but don’t expect some life-changing rewards.
