Playing is simple. Just click on the up or down arrows next to "Lines" to increase or decrease the amount of lines you want. The mini-game graphics will show you which lines you have chosen as you increase or decrease the amount of lines.
Eg: one line chosen
Then click on the up or down arrows next to "Stake" to increase or decrease your stake/bet.
Your Lines, Stake and Total are all linked. For example, if you choose three (3) lines and raise your stake (bet) to 20c, your total will be 60c (this is the default setting).
The possible winning combinations and their potential payouts are displayed if you click on "Pay Table" button.
The five betting lines are defined in order as:
Atlantis Gold Pay Table
Atlantis Feature Game
If you get a set of keys in the first reel on a line you have bet on, the game takes you to a different screen in which you need to choose three chests for a bonus.
Once you have chosen your three chests, the points will be added up to give you your bonus.
It is possible to play the feature twice. This will occur if you bet on five lines, and the key is present on the top or bottom of the first reel, or if you bet on four lines and the key is present on the bottom of the first reel.
