1v1 Math

Every number has its place. Will you find it before your opponent?

1v1 Math combines math grids with live, two-player duels. Fill in the empty squares to correct all the horizontal and vertical equations. Addition, subtraction, multiplication, and division await you in four difficulty levels.

PLAY AT YOUR OWN PACE
• Classic: Complete the grid before the time runs out, which is adjusted to the difficulty level.

• Sprint: Take on a three-minute challenge.

• Zen: A timer displays the elapsed time, with no time limit.

Daily Challenge: A new grid every day and bonus XP for your first success.

CHALLENGE A FRIEND
Create a private room and share its code, or find an opponent online. Both players solve the same grid. Track your opponent's progress, preserve your three lives, and try to finish first. Your friends can also join you from the browser version.

PROGRESS WITH EVERY GRID
Complete grids to earn XP and level up. Higher difficulties award more XP. Find your best times, average times by mode and difficulty, and recent games in your profile.

TOOLS AT YOUR FINGERTIPS
Sort available numbers, undo a move, or use a hint in single-player mode. Equation backgrounds and raised tiles make the grid easier to read.
You have three hints per single-player game. Each hint reduces the intended XP reward by 25%, including the daily bonus. Undoing a move or restarting a game does not reset the number of hints used.

Single-player games work offline. Duels require an internet connection. No email address or password is needed to play: a guest profile is used online. Choose French, English, German, Italian, or Spanish in the settings. English is the default language.
