Entertaining
The version I'm playing (1.9.3.3317) is yet another "ad-free" match 3 game featuring the now standard power-ups. Which means that in order to make any money off it, the developers need to make sure you can only advance so far before you need to buy powerups and or coins. However, unlike other such games (e.g. Royal Match), this one doesn't reach that point quickly if you play it half-way competently. Initially I got just past level 300 before hitting a pay-to-keep-playing point. I'm willing to watch some ads to support a game, but I'm poor enough I almost never spend actual money on games. So I just deleted it, reloaded it and started over. Now I'm still alive at level 345. To that point the difficulty level offers enough challenge to keep it entertaining. So it's not one of those games that are too easy at first, and then make a rapid switch to too hard. There isn't much to the "Solitaire" element: the one new-to-me feature is that some levels have icons of the back of playing cards (rather than the colored icons you match) typically several in a column below obstacles that can be destroyed by adjacent matches or power ups. Once the top obstacle is removed, all the icons above fall all the way to the bottom: BEHIND the cards. So if you have a power-up that falls behind the cards, though it's still there you can't get at it until you remove the cards - with matches or powerups remaining visible.
