Multiplication Practice
(Published on 29. October 2023, 11:31 by RockyRoer)
After my students have complained about my quizzes being too hard, hopefully here's an easier RockyRoer puzzle for you all. 2 points extra credit if you complete it without a calculator!
The Rules:
- Normal sudoku rules apply, so fill every row, column, and 3x3 box with the digits from 1-9 once each.
- [Odd/Even]
- Cells with a gray circle must be odd.
- Cells with a grey square must be even.
- [Products] In each region, the one-, two-, or three-digit number in the circled cell(s) is the product of the cells in the circles/squares in that region.
The Puzzle:
Solution code: Column 9 from top to bottom

Reply: Honestly, I double checked myself with a calculator in Box 3 and Box 5 too... :-)
