The crescent moon is the wild symbol, is can substitute for all the symbols except the scatters to help and form winning combinations and it offers a huge payout.
There are two scatter symbols, the planets and a globe, and they each trigger a separate bonus feature.
When the planets symbol lands on reels one, three and five simultaneously a bonus game begins. You will see the planets orbiting the sun at different speeds. This will come to a stop with one or more planet on the win line and each will add to a total multiplier prize.
When three or more globe symbols land on the reels the free spins are triggered. Landing three globes awards 5 spins with 1 reel modifier, four globes awards 10 spins with 2 reel modifiers and five globes awards 15 spins with 3 reel modifiers. The reel modifiers are extra features that you can choose that are then active for five spins. The Earthquake modifier will cause random symbols to disappear after each spin and be replaced by upgraded ones. The Lightning modifier turns up to four symbols wild after each spin. The Tsunami modifier will turn up to three reels completely wild after each spin.
During the base game a scroll can occasionally unfurl on the reels and award one of three bonuses: a multiplier and extra cash prize, one of the three reel modifiers from the free spins or an extra large win.
Nostradamus offers a huge top payout of 500x for landing either five wilds or five of the Nostradamus symbols along the reels. The book can payout up to 300x, the telescope up to 250x, the hourglass up to 200x and the parchment and quill up to 100x.
