Practise sudoku #6 - Sum or Product Frame
After the writing of all the sudokus and the selections, HSSC turned out to be a bit more math-oriented as expected. This Sum or Product Frame requires quite a bit of calculating too. It is really helpful to have a small table of possibilities for all the sums and products available before the contest starts. This practise puzzle contains a lot different clues. Use it to your advantage! 🙂
