Game Rules

Chests of Plenty

5-Reel, 20-Line Slot

The main objective when playing Chests of Plenty online slot is to spin the reels and land matching symbols on the paylines. This slot, with a nod to traditional casino games like online roulette and blackjack, also features Bonus Games and a Progressive Jackpot.

How to Play:

  • Select your bets using the + Bet or – Bet buttons on the bottom centre of the reels.
  • Chests of Plenty slot is always played with 20 fixed paylines. Therefore the Total Bet is calculated as Line Bet x 20.
  • When you have selected your bet, click Spin to start the game.
  • You can also set a number of spins to be played automatically using the Auto Play Function. Select Auto Play and choose from 10, 25, 50 or 99 Auto Spins, then select Spin to start Auto Play. The Auto Spins will spin automatically, only stopping if you are awarded a Bonus, or you select Stop Auto Play.
  • A winning spin will be clearly highlighted on the reels. Only the highest winning combination is paid on each payline. The amount won on each payline will be shown on the top left of the screen. The total win will be shown on the top right of the screen.
  • The payouts for all winning combinations are shown on the Paytable pages, which are accessed via the Paytable button on the bottom left of the screen. Line Win = Payout x Line Bet. Scatter Win = Payout x Total Bet.

Info Pages:

If you select the Paytable button on the bottom left of the screen, you will open the Chests of Plenty slot Info Pages. Use the arrows to move between the pages. Select Back to Reels to return to the game screen. The Info Pages are described below:

Treasure Chest Scatter – this page describes the rules and awarding of the Treasure Chest Scatter Bonus. It also explains how the Progressive Jackpot is awarded.

Treasure Island Bonus – this page describes the rules, awarding and payouts for the Treasure Island Bonus.

Paytable (1) – this page displays the payouts for high value symbols. It also provides information on the Wild Symbol and Pirate Wild Feature.

Paytable (2) – this page displays the payouts for all other symbols. At the bottom of the page an illustration shows how all 20 paylines appear on the reels.


Paylines are the pathways that matching symbols must follow across the reels (from left to right) to achieve a Line Win.

There are 20 fixed paylines in Chests of Plenty slot.

Please note the difference between the Line Bet and the Total Bet. The Line Bet is the wager made on each payline. The Total Bet is the wager made on all paylines.

About Payouts:

All payouts for Line Wins are displayed on the Paytable Pages. Line Win = Payout x Line Bet. Bonus wins and Scatter Wins are multiplied by the Total Bet.

Only the highest winning combination is paid on each payline. Multiple wins on different paylines are added together.

Wild Symbol:

The Girl Pirate is a Wild Symbol and can substitute for all other standard symbols to help form Line Wins on paylines. The Wild Symbol does not substitute for Treasure Island Bonus Symbol or Treasure Chest Scatter Symbol.

The Wild Symbol can also form its own unique Line Win with a separate payout when three or more appear on a payline.  

If a Pirate Symbol falls to the immediate right or left of the Wild Symbol, it too will become Wild and act the same as described above.

Scatter Symbols:

Chests of Plenty slot features two Scatter Symbols – the Treasure Island Bonus Symbol and the Treasure Chest Scatter Symbol. These symbols do not need to fall on any paylines to be active. If you land three or more of either symbol in any position after a spin, you will be awarded the relevant Bonus Game (described below).

Please note: The Treasure Chest Scatter Symbols have no payout value, although they award the Treasure Chest Bonus Game. The Treasure Island Bonus Symbols have a payout (for three or more), which is calculated x the Total Bet.

Treasure Chest Bonus and Progressive Jackpot:

Three Treasure Chest Scatter Symbols on any position on the reels award the Treasure Chest Bonus. It works as follows:

  • The Treasure Chests will expand and move to the centre of the reels.
  • The Bonus will begin automatically. The first Treasure Chest will open and three jewels will appear. If they are matching you will win a payout:
    • 3 Red Jewels = 1 x Total Bet.
    • 3 Green Jewels = 2 x Total Bet.
    • 3 Diamonds = 5 x Total Bet.
  • The next Treasure Chest will then open. The Treasure Chests will continue to open and pay as above until one reveals three jewels that are not matching. When this happens, that specific Treasure Chest will be locked and it will fade away from the screen. The other Treasure Chests will continue to open until they too reveal three jewels that are not matching. When all Treasure Chest have been locked, the Bonus will end and you will be awarded the total win.
  • If all three Treasure Chests reveal three Diamonds simultaneously, you will be awarded the Progressive Jackpot.

Please note: the software ensures that the Progressive Jackpot cannot be won by two players simultaneously. If two Jackpots are won in quick succession, the first player will win the Progressive Jackpot and the second player will win the Seed (base amount provided by casino).

Treasure Island Bonus:

Three or more Treasure Island Symbols will award the Bonus. You will also be awarded a payout, which is calculated x the Total Bet. The Treasure Island Bonus works as follows:

  • A new screen is launched. You will begin on one of three different Treasure Trails. The Treasure Trail you start on depends on the amount of Treasure Island Bonus Symbols that landed on the triggering spin:
    • 3 Bonus Symbols = Booty Island.
    • 4 Bonus Symbols = Isle of Plenty.
    • 5 Bonus Symbols = Jackpot Island.
  • You will be prompted to spin the wheel to move up the Treasure on each Island. The wheel can land on a number, which advances you that many steps up the trail, or Collect (Skull and Crossbones Symbol), which will end the Bonus.
  • Each square on the Treasure Trail can be blank (in which case you spin the wheel again), award a multiplier of your Total Bet, a Mystery Prize, or contain a Map. If you collect three Maps you will automatically progress to the next Island.
  • The Mystery Prize could be one of the following:
    • A Cash Prize
    • A Go To Symbol, which advances you to the next square with a Treasure Map.
    • A Spin Again award.
  • If you advance to the next Island Treasure Trail, your winnings will be banked from the last one.
  • If the lands on Collect, the Bonus will end and you will be awarded the current amount collected in the Bonus.

Please note: the Treasure Island Bonus is played with the same Total Bet as the triggering spin.
