You can play Flow Field Chess in your browser now — Rust compiled to WebAssembly, a thin shell around it, no server and nothing to install.

The premise, in one breath: it does not search. Each turn it raises five fields over the board — Pressure, Attack, Resistance, Trace and Flow — and you may pile on thirteen further borrowed algorithms (reaction–diffusion, Ising spins, lattice–Boltzmann and assorted friends), toggling and reweighting each one mid-game. It is not trying to be strong. It is trying to be interesting — and on a good day it manages to be surprising and wrong in the very same move.
