A puzzle site for people who look twice

Our eyes are quick and confident, and they are wrong more often than we notice. They skip over the key on the patterned rug. They swear two grey squares are different colours. They lose track of the third tile you flipped. Expercepth is built around those small failures, because catching one is a lot of fun.

We publish puzzles and short articles in five families, set in our own world: a twilight house of impossible rooms, where stairs loop back on themselves and something small is always hiding in plain sight.
