I'm trying to remember where I played this slot game before.
It has an initial spin - 3 reels - you select to keep 1, 2 or 3 of the reels and then the 3 lines above it are spun keeping your reel choices the same for each line and a random symbol spins for the other reels. The symbols include crowns, rings and genie bottles ( I think) with another symbol which I forget but whatever that one is, it gives you a 'feature' to select a treasure chest.

I think there is a similar game with different symbols but it plays the same way.
