Sia Doble

Sia Doble appears to be a two-player version of Oliver Schaudt's Sia Solo, a solitaire puzzle game in which the solver tries to swap the positions of two large stones on the game board. In Sia Doble, each player has three large stones and – I'm saying this based totally on gut-feeling – needs to place those stones in the starting spaces of the opponent's stones in order to win.
