Neither one has a fully symmetric clue layout, but I’m happy with them as they are.
Regular Masyu rules.
The full title of this one is Alternating Liars Masyu. In addition to regular Masyu rules, half the clues are liars: that is, a liar white pearl acts like a black pearl, and vice versa. The loop must alternate between truthful and liar pearls: going around the loop, every other pearl must be a liar.
This one is an Alternating Masyu. In addition to regular Masyu rules, the loop must alternate between white and black pearls: going around the loop, every other pearl must be black.
While using guesswork might be tempting, there is a particular insight this puzzle was built around.
I’m very happy with how both of these solve. On top of that, the 10×10 one also solves as a Star Battle.
Regular LITS rules.
This one’s one of my favourites from the hard end of the difficulty spectrum. However, you’ll need a little bifurcation, so consider yourself warned.
Regular Regional Yajilin rules. However, the clues have been encrypted: different letters stand for different numbers (possibly zero), and same letters stand for the same number. Determining which letter stands for which number is part of the puzzle.
I quite like Liar variants, I should make more of these.
Standard Futoshiki rules, with the following exception: in every row and column there is exactly one liar cell, and the inequalities surrounding the liar are false. Notice that cells without any inequalities around them may also be liars.
