It is a cascading slot machine with 7×7 reels. Symbols fall on the reels to form winning combinations. Wins are achieved by getting 5 or more of the same symbols when they are in a group that is vertically or horizontally touching. Winning symbols are removed and new symbols drop down to fill the reels.
Wins contribute towards filling the features meter. Get enough consecutive wins to fill each segment and the Olympus Box feature indicated by the color will be added to the queue.
Transforms up to 8 symbols into Wilds while removing adjacent symbols.
Places a Wild symbol in the centre of the reels. Creates 2 diagonal lines from the centre with the same random symbol. Random symbols will not replace any Wilds in their path.
Destroys all low pay symbols.
Selects 1 random low pay symbol, and all matching symbols and turns them into another symbol. If no low pay symbols are on the reels, any other available symbol is chosen.
When the Olympus Box feature meter is fully charged the Olympus Bonus is added to the queue. The Olympus Bonus first adds a 3×3 Wild Castle symbol to the grid in a random position. If no more cascades are possible, it then becomes two 2×2 Wild symbols, before finally ending up as nine 1×1 Wild symbols. New symbols drop down from the top to fill the grid before each move.
If no more cascades are possible, the Olympus Box features in the queue are triggered. The game round continues normally, allowing more features to be charged, possibly creating additional wins. Olympus Box resets only at the end of each game round when there are no more winning combinations.
After each spin, a total win multiplier is applied to the won amount. This multiplier corresponds to the number of features triggered in this game round.
When 4 matching low or high pay symbols are adjacent to each other in a square formation they transform into a single Super Sized 2×2 symbol. Wins are doubled if one or more Super Sized symbols are part of a winning combination.
On any initial non-winning spin, there is a chance for Zeus to drop up to 8 Wilds randomly on the reels.
A random low pay symbol is highlighted on each spin. If any of the highlighted symbols are removed as part of a winning combination they leave behind two 1×1 Wilds.
Substitutes for all symbols.
