About @CalcMaster
@CalcMaster turns quick mental math into a daily puzzle habit. Each day you’ll face a hidden equation: guess numbers and operators, get color‑coded feedback on what’s correct, and use logic (not luck) to solve it before you run out of tries. Build a streak by coming back every day, tracking your progress on the calendar, and watching your best streak grow as you rack up points. Whether you’ve got 30 seconds or 10 minutes, it’s a fast, satisfying way to sharpen your math instincts. Play solo or with friends: add people you know, compare scores on a live leaderboard, send and accept friend requests, and browse profiles and stats to see who’s really the sharpest. Earn points as you play and spend them in the shop on new profile emojis and backgrounds to show off your style while you climb the ranks. Sign in with Game Center to submit your total points and best streak to global leaderboards and unlock achievements as you hit new milestones; games played, win streaks, total wins, and lifetime points. @CalcMaster also works offline, saving games locally and syncing them automatically the next time you’re online, so your streak and stats stay up to date wherever you play.
