Fantastic logic game

Im sick of seeing my toddler mindlessly hurl birds at pigs and tap on ads. So I was relieved to discover this fantastic ad-free introduction to logic puzzles. It requires thinking, and teaches the basic skills for more advanced puzzle solving games. My 4 year old breezed through the Easy levels and is challenging himself with the Hard levels now.
