Crossmath: Math Puzzle Offline

Crossmath is a calm, clever math crossword puzzle game. Every row and column is an equation — fill the empty cells with the numbers below so that every sum works out. Simple to learn, deeply satisfying to master, and it plays completely offline.

🧮 HOW TO PLAY
• Tap an empty cell, then tap a number — or drag the number onto the cell.
• Rows read left to right and columns top to bottom: a + b = c, a − b = c, a × b = c, a ÷ b = c.
• Use every number once. Solved equations turn green.

✅ FAIR PUZZLES, EVERY TIME
Every puzzle has exactly one solution and can be solved with pure logic — no guessing. Answers are checked by the equations themselves, so a correct number is never marked wrong.

💡 HINTS THAT EXPLAIN
Stuck? A hint fills the next logical cell and shows you why: "55 ÷ 11 = 5". Learn the tricks instead of just copying an answer. Pencil notes and pinch-to-zoom help on the biggest boards.

🎯 FOUR DIFFICULTY LEVELS
Easy, Medium, Hard and Expert — from a relaxing warm-up with small numbers to large boards that need deep reasoning with all four operations.

📅 DAILY CHALLENGE
A new puzzle every day, the same for everyone. Build your streak, fill the calendar and earn bronze, silver and gold monthly trophies.

♾️ ENDLESS MODE
Stages get harder and mistakes stay hidden until you submit your board. You have three hearts — how far can you go?

⚔️ BATTLE MODE
Race a computer AI rival on the same puzzle and climb from Bronze to Diamond in monthly seasons.
