Battle Crunch Maths is a fast, brain-crunching mental-math game. Every round hands you a 20×5 matrix: twenty numbers, each transformed by five random operations - add, subtract, multiply, divide, squares, cubes and square roots. Solve the whole grid before the clock gets the better of you. • THREE DIFFICULTIES - Easy, Medium and Hard tune the number range and which operations appear. • MAKE IT YOURS - choose exactly which operations show up at each level. • WORKOUT PAD - scribble your working out on any cell; handwriting turns into your answer. • RESULTS & RANKS - accuracy, time, a correction sheet, and a rank ladder from Math Recruit to Quantum Overlord. • BATTLE A FRIEND - invite a friend to the same grid and race in real time. • CLASSROOM ROOM - run a live race for a whole class (25+ players) with a real-time leaderboard. • THEMES & WALLPAPERS - sage, ocean, forest and custom backgrounds. • FACE ID - optional quick sign-in. Fully playable offline. No ads. No tracking. Train your mental math anywhere. Terms of Use (EULA): https://battlecrunch.mytribe.club/terms Privacy Policy: https://battlecrunch.mytribe.club/privacy
