Mentamic: Two player math game

Mentamic is a strategic math and arithmetic game where you build valid equations on a 9×9 board using numbers, operators, equal signs, and parentheses.

What sets Mentamic apart from many other math apps is that you are not just competing against yourself. You can challenge friends, invite new players with a link, face random opponents, and climb the rankings.

In the app, you can:

-play solo and multiplayer
-invite friends via SMS, email, etc
-find and add other players
-chat with your opponent
-choose thinking time per move from 10 minutes to 3 days
-track ELO rankings and solo highscores
-use +, -, ×, ÷, exponents, and nth roots
-continue ongoing games later

Every move is about strategy, mental math, and timing. Build expressions that cross each other, use parentheses wisely, and maximize your score on the board.

Mentamic is for anyone who enjoys brain training, number games, logic games, and competition. Whether you want to practice alone or play against others, you get a math game with depth, social interaction, and a competitive edge.
