This week again one of my own ideas for the Daily League. I have posted a few of these already on my blog. I came up with this type as a response to the repetetiveness of Frame Sudokus. I always enjoyed solving Frame Sudokus, but after a while they get a bit the same. This rule set adds to the diversity of the solve as you now have more ways of creating openings and keeping the solving path narrower.
This puzzle is easier than the other Frameless Sudokus I have made, to make it more suitable for speedsolving. The path is solving path is still narrow, but you get a few easy digits to start off with. I think the equal sums on the left and right side are a nice touch. I was planning on making two sequences at the top and bottom too. Except the 16 and 18 clues wouldn't work in order with the other clues, but did work switched. So I figured that would be good enough. This puzzle can also be used as practise for the upcoming Serbian Round of the WPF Sudoku Gran Prix held from April 20th-April22nd, which features a Frameless Sudoku.
