Video Summary

The video explains a puzzle where seven different single-digit numbers are placed in circles, with each line of three circles having the same product. Numbers 5 and 7 are ruled out because no three-line products could universally include them. The puzzle requires the two horizontal rows to produce a square product, and considering allowed numbers after ruling out 5 and 7, the missing number under the question mark is determined to be 2. This allows a setup where each line's product is 72, with the correct configuration being: top row (1, 9, 8), middle row (3, 4, 6), and a column (9, 4, 2).
