1v1 Math
Math puzzles & friend duels
Free
Five ways to play with numbers. Choose a game and difficulty, then challenge yourself or a friend.
• Cross Math: complete a grid so that every equation is correct.
• Missing Signs: find the operations that complete the calculation.
• Memory Addition: remember disappearing numbers and keep adding.
• The Biggest: spot the highest number among moving tiles.
• Memory Grid: memorize the positions, then put the numbers back.
Each game has four difficulty levels. Animations accompany answers, mistakes and results. Depending on the game, incorrect answers add a time penalty.
CHALLENGE A FRIEND
Create a private room and share its code, or use the dedicated button to join a room. Choose the game and difficulty inside the room before starting. Play several rounds together and follow your opponent’s progress. Friends can also join from the browser version. Opponent search is available too.
FOLLOW YOUR PROGRESS
Earn XP, level up and view your scores, best times and recent games. Solo games are saved separately for each game when you leave. There is also a daily Cross Math challenge.
In Cross Math, drag tiles, sort numbers, undo a move or use up to three solo hints. Each hint deducts 25% of the full XP reward.
Solo play works offline. Duels need an internet connection and use a guest profile, with no email or password required. Available in English, French, German, Italian and Spanish.
No advertisements, subscriptions or in-app purchases.
