Loading the machine: grid, controls and virtual credits
The Gates of Olympus demo opens on a six by five grid with Zeus standing to the left of it. Thirty symbol positions, no paylines, no win line indicators. The controls run along the bottom: balance, bet field, spin, and a small cluster of secondary buttons that most players never open. Your first job at this machine is to open all of them, one at a time, and see what each one does to the interface before you commit to a single spin.
The credits sitting in the balance box are virtual. They were not deposited, they do not belong to anyone, and there is no mechanism anywhere in this client to convert them into money. That is not a limitation to work around, it is the entire premise of a free slot demo. It means you can do things here that would be reckless with real funds, such as running two hundred spins at maximum bet just to see the shape of the variance, and learn something from it.
