Cannonball Bay Slot from Microgaming

Cannonball Bay slot from MicrogamingMicrogaming’s 2013 Cannonball Bay slot machine welcomes you aboard one adventurous pirate ship, full of bounty hunters, marauders, and other shady figures, who are all ready to share their loot with you. While you are under the enemy’s fire, you’ll be spinning the reels in search of hidden treasures, trying to gather your own collection of coins to increase your balance.

The perilous pirate action takes place on a 5x3 grid, crossed by 25 pay lines, accompanied by bombastic sound effects to complete the pirate picture. Cannonball Bay promises an under industry minimum RTP of 95.8% and a Medium Volatility game process. You can put your gunpowder for free first in the DEMO version on our page. No registration is required.

Personal testers’ opinion

The Cannonball Bay online slot doesn’t stand with super high-quality graphics, sound, and settings. The general outlook of the machine is outdated and unappealing. It is not popular and not widely available. The bay doesn’t provide stable payouts in the base spins. Continuous insufficiently paying combinations (less than or equal to the stake) are slowly eating the balance. There is no recovery even with the Free Spins. You will never see a full screen of Cannons (Wild symbols, top value of 2000 coins for 5OAK), not even 5 of them. What you can expect is long waiting for the bonus round. When you actually get it, it consists only of 5 Free Spins (re-trigger is only possible on papers - according to our test sessions), with no multiplier. So, don’t hope for much, as the average payout of the bonus round we established is only between 35x and 40x the bet, despite the multiple explosives. To top it all, the slot has one very low score at our wagering scale records - 3.79 (out of 10), which indicates that Cannonball Bay is not suitable ammo for the bonus shooters/hunters.
