First release! Math crossword puzzles with four difficulty levels, a Daily Challenge, Endless mode, AI battles, achievements and leaderboards.
Math crossword puzzles: fill the grid so every equation adds up. Play 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. 🏅 LEVELS, QUESTS AND ACHIEVEMENTS Earn XP, level up from Beginner to Grandmaster, complete three daily quests to open a reward chest and unlock 16 achievements. Compare your scores on Google Play Games leaderboards and keep your progress in the cloud. 🧘 DESIGNED TO RELAX • Plays offline — no Wi-Fi needed • Light and dark themes, large numbers option and your choice of ÷, : or / for division • Optional mistake limit, timer and auto-sorting of numbers • Calm music and gentle sound effects you can switch off • Small download, quick to start Crossmath is a brain training puzzle for fans of math puzzles, number games, sudoku, kakuro and crosswords.
