Yes, it's actually one of the main ones. Daily drops rotate through a handful of featured slots each day, and Gates of Olympus has shown up in that lineup pretty regularly since I started paying attention a few weeks ago. Played it during one of the drop windows myself, small mystery prize landed after a handful of spins, nothing huge but still fun. Rotation seems to favor higher volatility titles for the drops, which makes sense given the bigger swings people are chasing. Full schedule of which games are currently in the drop rotation is listed on the hellofortune premium casino club page, easy to see each morning before deciding where to play. Winnings from the drops landed straight in the cash balance, no wagering attached at all
