A puzzle expert, on Reddit, solved all the Alcazar puzzles on the website with very clever techniques, and recommended that I give a preview of some advanced puzzles.
Good idea! Here are 2 pages from Alcazar - Volume I that I would normally recommend to experienced Alcazar solvers.
Warning: these puzzles are for experts only! If you feel ready to try them, feel free to print the following pdf page.
If you need to guess and erase too much, it just means that you need some practice. For that, the Alcazar book is available, and contains 100 puzzles from the easiest to the most difficult!
