SQR 4 is a colourful mathematical puzzle. The player's point is to make each line's digit sum equal to appropriate column's sum using addition (+), substraction (-), multiplication (×), division (÷), squaring (^), square root extraction operation (√), concatenation (∨) and clipping (∧) only. Concatenation assigns the number after to the right of the number (13∨6 = 136). The clipping removes the indicated number of digits from the number to the right (358∧1 = 35).
