1v1 Math

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.
