The way I did it was to play the games over and over. I add the Amulet of Searching for 5 Rubies and the Experience Amulet for 3 Rubies each time I play. That usually gets me 5-6 Vials of Magic Salt for each wine. Expedition is the best game to play, then Chrystals, then Cards. Each time you get 25-30 vials, play the room of fate. Also, redeem your magic gifts as often as you get stars - they will help you when you go to assemble your collections. Fighting the monsters only gets you 1 star each, so they don't help much. It takes a long time to do it this way, but you will assemble collections along the way, increase coins and experience, gain collectibles, and increase your levels.

Hope this helps!
