## What is MathDoku?

MathDoku turns a quiet ten minutes into the best brain workout in your day.

Inside every grid is a small, elegant arithmetic puzzle (also known as Calcudoku): fill each row and column with the numbers 1 to N without repeats, while the cells inside each outlined "cage" combine — using add, subtract, multiply, or divide — to hit its target. No guesswork. Just clean, deductive reasoning.

WHY YOU'LL LOVE MATHDOKU
• 180 hand-curated, uniquely-solvable puzzles across 6 difficulty tiers — Easy 4×4 all the way up to Grandmaster 9×9.
• A free Daily Challenge every calendar day — the same puzzle for everyone, with a streak that grows the longer you keep showing up.
• Smart hints that point to the next deductive move when you're stuck, never the answer.
• Stars, best times, and progress that unlock the next world as you sharpen up.
• Five gorgeous themes — Parchment, Midnight, Meadow, Orchid, Sunset — pick the mood, then crush the grid.
• Subtle sound and haptics that celebrate every correct placement.
• Game Center leaderboards and achievements when you want to compete.
• A shareable solve card so you can flex on the group chat.

BUILT TO LAST
• Fully offline. No accounts. No network. No ads. No interruptions.
• Color-blind palette, VoiceOver labels, Dynamic Type — accessibility built in.
• Right-to-left layout for Arabic; localized in 11 languages.
• Onboarding teaches by doing — tap a real puzzle, no walls of text.

MathDoku is the puzzle for people who love crosswords but want something more rigorous, for sudoku fans who want a sharper challenge, and for anyone who finds calm in the click of a number falling into the only place it can possibly go.

Open the app. Solve one. See the streak begin.
