A two-player tabletop duel. Two players sit across a kitchen table and share the five signal stones between them. Set one on an open peg, spin the core or the outer ring, and watch the whole layout shift. Good for a game night, a study break, or anyone who likes a rematch that never plays the same way twice.

One turn moves every stone. You press a signal stone onto an open peg on the five-job core, then turn either that core or the outer counter-orbit ring by hand. The turn carries every stone already seated to a new spot against the ring's rim, opening or closing the three-point wedge both players are chasing that match.

The pieces and how they seat. The set comes as the counter-orbit ring, the five-job core disc, and five spoke-signal stones, one for each job. Each stone presses onto its own peg on the core; the core then drops inside the ring and spins free against its scalloped rim, no glue, pins, or hardware holding it together.

Fit, spin, and finish. The core rides inside the ring with just enough clearance to spin free by hand, no bearings pressed in to do it. The ring's rim carries eight cut stops that keep its edge crisp, layer lines run fine and even across every face, and each peg holds its stone snug without wobble or glue.
