I found the puzzles to be pretty hard, for the first one I had to look at 2 hints, when I realized the solution it made feel a little silly cuz it wasn't that hard. With the 2nd one I pretty much solved it on my own cuz I put together pretty fast what to do. with the 3rd one, I gave it a honest try but I think I'm missing something because I just don't understand how to solve it I did try to determine who the liar is and to add up the numbers but I couldn't figure it out and I don't really understand what I am supposed to do with the result since it asks me to enter a date and all results I uncovered were unhelpful in that regard
