The Great Jackpot Expedition

Drawing inspiration from Captain James Cook's legendary voyages, The Great Jackpot Expedition by Octoplay channels the spirit of 18th-century maritime discovery. While Cook charted unknown territories like Hawaii and New Zealand, players chart their course through a unique 10×10 bonus grid, seeking their own discoveries in the form of jackpots and treasures.

Breaking New Ground: Core Innovation

Octoplay introduces their first-ever persistent progress system in this nautical adventure. The game's standout feature lies in its progress tracking mechanism – a revolutionary approach where bonus symbol collections remain saved across gaming sessions. This permanent progression system creates a genuine sense of advancement, transforming each spin into a meaningful step forward.

Technical Specifications: By the Numbers

The Great Jackpot Expedition operates on a traditional 5×3 grid with 10 paylines. With an RTP of 95.80% (slightly increasing to 95.82% with Double Chance enabled), the game positions itself slightly below the industry average. The volatility stays in the low range, making it suitable for extended gaming sessions. Players can wager between 0.1 and 100 credits per spin.

Wild Scrolls: A Dynamic Multiplier System

The game's base game excitement stems from its innovative Wild Scroll mechanic. Each reel features a progress bar with levels corresponding to its position – reel one has one level, reel two has two, and so forth. When Wild Scrolls fill these bars, they trigger expanding wilds with increasing multipliers. These wilds remain active for spins equal to their reel position, with multipliers growing by 1x each spin. This creates a strategic layer where players must consider the potential of each reel position.

The Heart of Adventure: Jackpot Expedition Feature

The bonus game transforms into a sophisticated 10×10 grid adventure, reminiscent of classic board games but with modern twists. A compass-guided ship navigates this expanded space, capable of wrapping around edges for continuous movement. The feature begins with two locked areas – a 3×4 and a 3×6 region – that unlock through persistent progression.

Three distinct prize sectors await discovery:

Cash Prizes range from 2x to 25x, strategically positioned across the grid. Each prize can be claimed once per feature activation.

Treasure Chests serve as game-changing power-ups, offering multiplier increases of 5x or 10x to uncollected prizes, or deploying additional ships toward valuable targets.

Jackpot Islands require complete coverage for massive rewards, scaling from the Mini Jackpot at 50x (single sector) to the Grand Jackpot at 750x (four sectors).

Progression and Persistence

The bonus progress system tracks scattered compass symbols across two significant milestones: Level 1 requires 20 scatters, unlocking the 3×4 region Level 2 demands 30 additional scatters, revealing the 3×6 area

This progression persists between sessions, creating a genuine sense of advancement over time.

Strategic Depth

Despite its low volatility, The Great Jackpot Expedition offers meaningful strategic choices. Players must decide whether to activate Double Chance, weighing its 40% cost increase against doubled bonus trigger rates. The bonus game itself presents tactical decisions about optimal ship movement paths, especially when multiple prize sectors are within reach.

The Great Jackpot Expedition represents a bold step forward in persistent progression slot design. While its 2,500x maximum win potential might seem modest, the game compensates through consistent engagement and strategic depth. The combination of expanding wild multipliers and a sophisticated bonus board creates a compelling gameplay loop.

The persistent progression system stands as the game's greatest innovation, offering players a genuine sense of advancement rarely seen in slot games. However, higher volatility players might find the win potential limiting.

The game successfully bridges the gap between casual and strategic play, offering enough complexity to remain engaging while maintaining accessibility. It's particularly well-suited for players who enjoy methodical progression and tactical decision-making in their slot experience.
