(Published on 18. February 2021, 16:36 by bigger)
All the following puzzles would be under valentine theme. In other words, idea comes from valentine itself. So, hope you guys would enjoy.
Standard sudoku rules applies. Fill the grid with numbers from 1 to 6 so each digit occurs exactly once in every row, column and 2x3 box.
Cells with a arrow means the cell that is n cells away that direction is 7-n, where n is the number in the arrow cell. In other words, arrow cell and the pointed cell are a pair/sum to 7. Not all arrows are shown.(how)
this one for warm up.
this one for real.
This puzzle is made by Old Miles from China. This idea is hellish hard. It's harder than mystery box. The problem Old Miles has to deal with is to make a doable puzzle for me, which means, the hard one won't be shown.
Solution code: Row 5 first one then second one (12 digits)
