Each shape represents a (unique) positive whole number. The sum total of the shapes in each row or column is displayed at the end of each row or column. Use this knowledge to deduce the numerical value of each shape. To set the value for a shape, 1st click on the digit in the 10-key keypad on the left. Then click on one of the four shapes, just to the right (not on the 4x4 grid). Solving tips: Try not to guess. Try to use algebra. Treat the rows and columns as a set of "simultaneous equations".
