Pacific Boom Slot Review

Pacific Boom Tested — Core Gaming

For a 5-reel game with 20 lines, Pacific Boom extracts a lot from its frame. The submarine warfare theme carries through each part of the design. What follows was tested in real sessions on July 22, 2026.

The Numbers

Per-line bets begin at 0.01, and the top bet reaching 100. At 20 lines to work with, dead spells stay short. Like always: variance rules short sessions — play within your budget.

A Closer Look at the Symbols

The symbol set features game logo, PT boat, submarine and torpedoes — cohesive and readable even at speed. The wild here is the depth charge wild, substituting for other symbols on wins. The gold bonus, mine runner, royal blast, wild ranks and battlesubs acts as the scatter. Wild plus scatter gives Pacific Boom dual engines for surprise payouts.

Unlocking the Features

Land random chance activation and the Bonus Modifiers kicks in — arguably the game's best stretch. A second round — its Mine Runner — stacks an extra dimension. Feature number three follows: the Royal Blast Free Spins. Still — a Wild Ranks brings yet another way to win, through landing two gold bonus symbols on reels 1 and 3 along with the wild ranks bonus symbol on reel 5. Add the Battlesubs Free Spins to the list as well — landing two gold bonus symbols on reels 1 and 3 along with the battlesubs bonus symbol on reel 5 brings it off. Topping off, the Party Pots Jackpot Feature (triggered by random chance during any spin) caps the exceptionally deep feature lineup. And there's the jackpot: Pacific Boom is one of Core Gaming's progressive, so the max prize grows as players spin worldwide. Spins remain engaging between features — a sign of good base-game math.

Best Casinos to Spin
