The Great Jackpot Expedition

The Great Jackpot Expedition slot game is based around adventure and exploration. This online slot has a lot of old-fashioned explorer vibes and even incorporates a pirate theme to go along with the exploration ideas.

The Great Jackpot Expedition slot game is made by Octoplay and is a relatively simple game. It is played across five reels, but it also has a lot of bonus features and added extras. There are 10 paylines and the maximum potential payout is 2,500 coins.

The lower paying symbols are 10, J, Q, K and A, while some of the higher paying symbols include the Anchor, Green Flask, Binoculars and Explorer. Players need to land five or more matching symbols on a payline in this video slot game to trigger a payout.

For those who enjoy exploring, this could be a good option among the online slots available at LeoVegas.

With its relatively simple base game, The Great Jackpot Expedition slot game has loads of different bonus features and minigames, including:

The Jackpot Expedition feature activates when three Scatter symbols land on reels 2, 3 and 4, granting three Free Spins. Players are transported to an interactive game board with a 10x10 grid, where a ship navigates across the board. Each time the ship stops on an unclaimed prize sector, the Free Spins counter resets to three, adding more chances to win.

A player’s movement during the feature is directed by a compass located on the right side of the screen, determining both the direction and number of steps the ship takes, with up to six steps possible per spin. If the ship reaches the edge of the map, it reappears on the opposite side, keeping the gameplay unpredictable.

The Wild symbol plays a key role in creating winning combinations, substituting for all symbols — except the Scatter symbols. Landing five Wild symbols on a payline delivers a payout of 50 coins.

Beneath each of the five reels is a Wild Symbol Progress Bar, with levels corresponding to the reel number — reel 1 has one level, reel 2 has two, and so on. Every time a Wild lands on a reel, its corresponding Progress Bar fills. Once full, the entire reel transforms into an Expanding Wild on the next spin.

These Expanding Wilds lock in place for a set number of spins equal to the levels on the Progress Bar. For example, if reel 5 activates an Expanding Wild, it stays locked for five spins. Each Expanding Wild begins with a 1x multiplier, which increases by one with every spin it remains on the reels.

The paylines of this slot are relatively simple and players need to match three or more symbols, starting from left to right, across one of these paylines to trigger a win. The more symbols matched, the higher the potential return.

The card symbols have the lowest payouts but the Explorer and Green Flask can trigger higher wins.

Of course, there are bonuses, and it is possible to trigger these by landing Scatter symbols. Three or more Scatter symbols can trigger the Free Spins round.

Like many Octoplay slot games, The Great Jackpot Expedition video slot is really easy to control and play. The controls are at the bottom right of the reels and players can simply choose their stake and hit the spin button.

The game can be played on a wide variety of devices. It has been optimised for play on mobile devices as well as on computers. Both Android and Apple users will find it easy to load and play the game on their browsers.

The Great Jackpot Expedition online slot was released in 2024 and has a modern feel to it with crisp graphics. It is set on an island and the scroll and pirate imagery help to set the theme of setting sail and exploring the world. There’s quite a grandiose feel to the game as a result.

This Octoplay slot also has a sense of humour and doesn’t seem to take itself too seriously. It is one of many video slot games that has a fun outlook.
