I really like logical puzzles; in particular I love ones in which the solution is on reach without complex computations; however I like also ones in which complex reasoning leads to surprising results.

Here I collected some of the puzzles I liked more with their solutions. Sometims they're puzzles I invented, a few others are ones I just solved and some others are ones I wasn't able to solve myself (so the solution presented isn't mine).

If you know a puzzle or logic problem that you think is particularly interesting or if you don't like the solution I presented to the ones listed here (either because you have better ones or because you think mine are wrong) then don't hesitate in contacting me.
