I rated this 1/5 difficulty.
Neat FoW puzzle, and it made for a fun & quicker solve!
I liked the break-in a lot, and it was a very nice and approachable way to start a FoW puzzle. Throughout the solve, liked how each "type" of rule sort of formed their own "mini-puzzles" and I could just work from one clue type to the next. I imagine that during the midgame you could probably tackle sections in different orders, but this is really not an issue and the solve path/logic would mostly be the same. The fog mechanic still ultimately forces the solver to follow the different sections on their own.
This puzzle would definitely be a great way to introduce a beginner to a several different sudoku variants. The puzzle showcases a lot of common rulesets, and uses a lot of "big ideas" for each of those rules that show up in other puzzles. The fog aspect would help orient the solver to focus on one type of rule at a time, without being too complex or overwhelming. The break-in may be a bit too tricky for a true/total beginner, but the fog would definitely help make this more approachable and force them to take the time to "understand" each rule. The renban lines being yellow instead of magenta (and the yellow square) may potentially be a bit confusing for this "true beginner" scenario, but of course this is purely visual and it definitely appears to be a conscious choice in order to preserve the final thematic "picture" made by the clues.
Even if you're not a beginner, this puzzle is also nice for more advanced solvers who are just looking for an enjoyable & approachable solve.
Thanks for sharing!
