Always wanted to be a super hero? Have that super skill that everybody admires? Like a Jedi? Of course, you do. Who am I kidding? This game can make you a super hero in MIND MATH. Sounds nerdy, but it is super fun. And super complicated. At the beginning. The rules are dead simple: you have to find 3 numbers that give you a given number. As fast as possible. (Yes, look up in the tutorial the details. It is still that simple). So. As fast as possible. ASAP (Like it is always in life). And this is where it gets tricky. You will probably suck at first. But the good news is - you can get better. Much better. The average time you need for an answer is the ultimate measure of your skill. Your goal must be to get to 6 seconds on average. You'll start somewhere around 100 seconds. Feels terrible. But you can do it. I can do it and my sisters can do it. So you can do it too. Just train. Like a Jedi. Do not let failure disturb you. Tell your friends - let them suffer too. Watch the daily world scores on the score board. And when you get to 6 seconds you will feel the force. Believe me. It is worth it. Sincerely yours. P.S. Forgot to tell you: my sisters and I can actually do the 4 seconds. But focus on getting to 6 secs first. 4 secs is another feeling.

Verdict

The call

The clearest difference is review sentiment: Math Rings at 100% against 3o's 50%. 3o's advantage is rating (4.8 vs 4.2) and update cadence (every 6 weeks vs every 20 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

3o holds the better App Store score, 4.8 against 4.2. Both are backed by a comparable volume of ratings — 5 and 4 respectively. Written reviews complicate that: 100% of Math Rings's written reviews are positive against 50% of 3o's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Math Rings ships an update every 20 months, 3o every 6 weeks. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
