About Senso

Senso is a small collection of perceptual precision games. Each one isolates a single dimension of perception — time, colour, pitch, quantity, or orientation — shows you a stimulus, removes it, and asks you to reproduce it from memory.

The idea is simple and a little humbling: our senses feel vivid and exact in the moment, but memory of a raw sensation decays fast. Senso turns that fragility into a game you can measure, share, and slowly improve at.

Every game is free and works without an account. Scores are computed on a shared perceptual curve so a 40/50 means roughly the same effort whether you're matching a colour or a duration. Daily challenges are identical for everyone in the world, and challenge links replay the exact same targets.

Senso is built as an open, extensible engine: adding a new sense is implementing one interface. If you have an idea for a seventh game, we'd love to hear it.
