How the Game Plays

The Great Jackpot Expedition by Octoplay takes you on a nautical voyage across uncharted waters. Set on a standard 5x3 grid, the base game features maritime symbols like anchors, monoculars, and the courageous captain. Winning combinations are formed across 10 fixed paylines, but the real depth lies in the stateful progress system. Below each reel, players fill individual progress bars to trigger Expanding Wilds that remain sticky for multiple spins and carry growing multipliers.

Jackpot Expedition Explained

Landing three scatter symbols on the middle reels triggers the titular feature. The game transforms into a 10x10 grid where a ship moves based on a compass dial. This round begins with three spins that reset whenever the ship lands on an uncollected prize. Players can navigate to Cash Prize sectors, Treasure Chests that multiply existing rewards, or specific Jackpot Islands.

Bonus Progress & Jackpots

A unique aspect of this slot is its permanent progress bar. As you collect bonus symbols, you unlock additional 3x4 and 3x6 regions on the expedition map, which remain open for all future bonus rounds. Unlocking these areas is essential to reach the Major and Grand Jackpot Islands, offering fixed rewards of 250x and 750x respectively.
