I don't mind this app but find it incredibly frustrating that most plurals aren't allowed, anatomical structure except obvious eg heart, ulna, try smaller ie microscopic and not allowed. English spelling vs USA spelling is another problem. And as for free spins once I had 15 spins and 11 on them landed on 3 points, another time 4 out of 4 landed on the 3. Does my device have a weight in it 😂😂. One really good thing is not a lots of ads for a free game, so congratulations on that.
