A wall is coming. Transform your number into the target before it hits you.Press 1 – 4 or tap the operation buttons.
Learn the core rules in four quick, interactive walls.
Transform your number into the wall's target before it reaches you.
Your number is in the center. The target appears in the equation and on the incoming wall.
Press 1–4 or tap an operation. Some puzzles require more than one operation.
Match before impact. Solving in the final highlighted section earns +15 Perfect points.
Each consecutive clear adds 50% of the wall's base score. A crash resets the combo.
Slow creates thinking time, Undo reverses your last operation, and Skip removes one wall.
Every fifth wall is tougher, worth more points, and restocks one use of each power-up.
No lives, no pressure, and no score records. Choose your learning level.
