Bejeweled 3 has been out for years. If you're looking for a simple pastime with just enough strategy and frustration involved to keep you from falling asleep, but that isn't solitaire, then this is the game for you! Or, for me, at least. The app includes several tougher variants that offer more of a challenge than the namesake game, for people wanting more of a hassle in their time-killers. There are options WRT volume of sound, screen-size, cursors, background, and resolution.
But, IMO, I don't see any reason to update, if you're happy with 2. There's no difference worth worrying about.
FWIW, Bj3 works fine with El Capitan, with no probs at all.
