Seriously a great app

It's addicting and at the same time teaches me both tricks and novel ways of thinking with math. I'm around numbers all the time at work and school, so the challenges and secrets of math this app reveals is priceless to me. Yes, I'm a huge fan and I play this on the train and before I go to sleep at night.

Love this app

One ask: I wish the "play" selected categories were persistent. I.e. The ones you selected the last time you played are selected them next time you played.

Update: Reiterating this one year later. Still love the app, but I would use it regularly if I could “set” which Play categories I wanted and they would stay set every time I opened the app

Great strategies but can you consider elementary

We love the strategies and the app. But my 3rd grade daughter cannot practice because all the numbers are at an advanced level. She wanted to practice her 4’s but she got 4 Times 66. That’s pretty tough for a 3rd grader. Can you add something in the settings to simplify the practice?
