Review of Phi-Brain ~ Puzzle of God
Phi Brain is an anime about a puzzle god doing what he does best. This is an anime about a master of puzzles being challenged to solve lots of puzzles and uncover secrets in a high-stakes life-or-death game. Episodes consist primarily of puzzle-solving and explaining solutions. It is pretty good at having creative and unique puzzles for the most part, but there are also enough recognizable ones mixed in that you can try to think through it yourself as well. The characters are a little two-dimensional, but the characters aren't really the focus of this: it's the puzzles and solving them, and for that, youonly really need the MC. It's also over-the-top AF, ranging from deadly puzzles with the world at stake or even more deadly cookies baked with the best of intentions.
If you like big-brained MCs doing what they do best then you will like this anime. An interest in puzzles or death games will also make this more enjoyable.
Of Note: The opening is amazing. Also they play a bit of music when the MC is being particularly big-brained that really gets me going, and all the sound works toward the anime really well.
