A Sudoku With Only 1 Given Digit?!

** TODAY'S PUZZLE ** This sort of title heralds a sudoku by Aad van de Wetering, the Dutch wizard. This one is called 24 Squares! and it's "classic Aad" - a simple ruleset and a surprisingly deep and satisfying logical exercise. This puzzle does not play to any sudoku strengths Simon may have...!! Play the puzzle at the links below: https://sudokupad.app/oso53h7rd2 Rules: Normal sudoku rules apply. Each line contains a square number reading from left to right (or in the case of the line in r3c1, from top to bottom). eg If r8c7 was a 2 then r7c8 must be a 5 (to give the square number 25). (As an aide memoire, all 2-digit squares and 3-digit squares (without zeroes or a repeated digit) are: 16, 25, 36, 49, 64, 81, 169, 196, 256, 289, 324, 361, 529, 576, 625, 729, 784, 841, 961). ▶ LAST NIGHT'S BLUE PRINCE STREAM ◀ Here at 10pm UK time: https://youtube.com/live/OCmA4gubvks ▶ BLOBZ' WORM: OUR BRAND NEW APP ◀ We've released a brand new collection of sudoku puzzles by Blobz.
