Hit the board
Games where the world’s chess traditions meet.
Chess, ōgi and xiongqi on one shared board — built on open protocols, with an identity you hold yourself.
Traditions that meet, not merge
Chess in Europe, shogi in Japan, xiangqi in China: parallel traditions, equally deep. Sashité brings their spirit onto one 8×8 board so any of them can play any other — each keeping its own rules.
An identity you hold
Your account is a cryptographic key that never leaves you. No sign-up, no email, no password — and your games are signed, public and portable, on a relay you can read them back from.
Open, down to the notation
One board notation, one piece notation, one move notation — published as open specifications, with reference implementations anyone can build on.
