The Great Jackpot Expedition

Win Lines

All symbols pay from left to right on the defined paylines.

Wild Scroll

The Wild Scroll symbols are Wild symbols that substitute all other paying symbols.

There is a progress bar under each reel. The levels of the progress bar are equal to the number of the reel they are under and are updated each time a Wild Scroll symbol lands on the reel. When a progress bar is filled, the entire reel is filled with a Wild symbol on the next spin, which substitutes all paying symbols. At the start of the game, the progress bars under all reels have the first level filled, except the first one.

The Wild symbol remains on the slot for a number of spins equal to the number of Wild Scrolls needed to fill the progress bar, they also have multipliers with a starting value of xl, that grows, which is applied to all wins that the symbol is part of. The multiplier grows by +1 after each spin that the Wild symbol remains on the slot. Bonus symbols can land on top of big Wild symbols.

Jackpot Expedition

Bonus symbols can only land on the middle 3 reels. Landing 3 Bonus symbols triggers the Jackpot Expedition bonus. The Jackpot Expedition begins with 3 free spins. Each time the ship lands on an uncollected Prize sector, the free spins are reset to 3. Each time the ship lands on a collected Prize sector, the free spins amount remains the same.

At the start of the Jackpot Expedition, the slot is transformed into a 10x10 grid with 2 locked 3x4 and 3x6 regions and a ship, which appears in the middle of the slot. On each spin during the Jackpot Expedition, the ship moves for an amount of sectors in a direction chosen by the compass. The ship can cross up to 6 sectors in one spin and if it passes through one of the edges of the map, it appears on the other side.

There are 3 types of Prize sectors on the grid during the Jackpot Expedition:

- Cash Prizes

- Treasure chests

- Jackpot islands

When the ship lands on top of a Prize sector its prize is awarded. If the Maximum Win of the game is reached the feature is terminated.
