How the orbit duel plays. Each turn, a player sets one signal stone into an empty inner or outer well, then rotates the outer orbit exactly one notch. That turns every occupied inner station toward two new outer wells. A three-signal wedge across the core and orbit wins; otherwise all ten signals resolve the match.

Two board pieces, ten stones. The set is two printed pieces plus stones: a 2.8-inch fixed core with five inner wells sits inside a 4.1-inch rotating outer ring with ten outer wells. Ten signal stones about 0.291 inches wide split into two tactile styles — five ridged-top ring stones and five smooth-top spoke stones — plus a printed rulebook.

Finish built for touch, not just sight. Ring stones and spoke stones are shaped, not colored, to tell apart: a ridged, fluted top on one style and a smooth, flat top on the other, so a hand can find its own signal by feel alone. Every surface keeps a fine printed layer finish, and the outer ring seats close enough to turn in one clean notch at a time.
