Mind Equation Puzzles

I love this app. I love that it's free and I love that they keep adding puzzles. The only problem I have is that the bottom of the screen, where the "notes" buttons are, is being reclaimed by iOS. The 1 and 9 are cut off by the rounded edges, the 9 is taken over by a new pop up thing, the 4-5-6 have the new "swipe up to close" bar. It's getting harder and harder to use those.

Great game for keeping the brain sharp. My arithmetic has improved greatly. I don't care how weird the scoring can be or whether I'm timed or not. I can always go back under stats and re-do a puzzle. A few had multiple answers but I don't expect perfection. It was only a few of them. I thought they were endless so I was disappointed to hit the end. Fortunately new puzzles are being created in a timely manner.

Played it about every day. Completed all 620 games. They get progressively more difficult which helps you develop your skill at the game. Enjoyed the game immediately before going to sleep at night. Found that when I began to have difficulty with a puzzle it was time to go to sleep, then could easily solve later the next day.
