Halloween Breakout

Getting very confused. I play 'proper' Sudoku every day. I buy little books and fill in with pencil by hand. These puzzles are completely different and I am struggling. Will have to make an executive decision as to whether to bother after I finish the first tower. I might cut my losses and get back to stocking up with crops to feed all my pens. This is the first event I have done for since the spring and seeing Sudoku drew me in. Easy, thought I. Big mistake, said I. Reading all the above makes me think I will never understand what to do next.

 

The note function (the icon with a 3x3 grid of squares) allows one to mark possible numbers for a box.

 

They should introduce a button to clear all the grid. The sudokus in Tower 3 are getting harder and harder, I'm using the maps to unveil a number just to fast track this.

 

This is easily the most confusing, annoying, and time-consuming event in ages—for me, it tops them all. Sudoku with a twist? why just to annoy us. I was so looking forward to it, but now I’m totally spent and not even sure I’ll continue. I completely agree with Northy: a clear button would have made this way less aggravating. Good luck everyone!
