I have some puzzle ideas eg
Some sort of sign and inequality mixture,
some sort of odd/even loop puzzles,
some sort of sudoku variant,
some sort of triangle weaka style sudoku variant,
some sort of !Puz loop/puzzle,
some sort of love heart puzzle,
maybe a 1-away killer, a 2-away killer etc etc.
PUZZLE BOOK IDEAS:
I may make a book of 3-away product frame odd pair sudoku
Or how about a book of Battle Symbols? I do not recall Errre having one.
A book of Sum Skycrapers, and a book of Product Skyscrapers
A mixture book of 5-away Sudoku, 5-away Killer, 5-away Kakuro, 5-away Futoshiki and 5-away X-Factor.
