I have reviewed all the level 1 puzzles so far. I am sure there will always be new level 1 puzzles.
I don't think I will update this page (but I will see later) because it would be long to find it.
So far, you can find:
My favourite is the Cast loop: it has a nice design, is tricky to reassemble even if you disassembled it few minutes ago and is always fun to solve. I like the feature with the magnet.
I like also the Cast shark.
My less favourite puzzle is cast hook. Well, the puzzle is far from being obvious, but what I like less is that there is a bit of friction and you really need to make tiny moves to solve it.
Don't get me wrong, it's a nice puzzle, but just not my favourite one :-)
What's your favourite level 1? And your less favourite level 1?
