For context I have Murdoku Volume 1, portuguese version. I‘m actually losing my mind. Many of these I cannot solve by myself and have to check the step by step solution in the back and I STILL don‘t get it. For example, in puzzle 37 the solution in the back says something like „… which isolates G in the last car“ when I still have 2 cars available even after following the step by step solution. This has happened in at least 4 other puzzles so far. I love sudoku but this is really frustrating me. Is it just me?
