I had become addicted to this game. Thoroughly enjoyable.
However, after reaching about a medium level, I found it impossible to go any further without using any gems, which are very quickly depleted.
Almost every aspect of this game relies upon using gems, as opposed to coins— from choosing an extra category, to receiving a hint on an answer, to getting an extra spin.
Furthermore, there is a “glitch” (is it really a glitch?), supposedly allowing you to watch videos, to freely earn a small number of gems...
But after watching these videos, no gems are received!!
I have the latest version of this game installed, so that has nothing to do with the “error”.
The *only* way to obtain the gems is to buy them.....I have already laid down money once, in removing the ads...lI refuse to do it again.
Why can’t the user occasionally exchange some of the amassed coins or stars, for the gems?
And without accumulated gems, it is practically impossible to advance any further in the game.
Too bad, because this is otherwise a wonderful app, and an entertaining pastime.
Other suggestions:
Where are the categories like spelling, grammar, and mathematics? ...or maybe I am just old fashioned.....
Also, how about classic TV and films, and classical music categories?
....Way too many “pop culture” entries from the year 2000 and up—at least for this user.
