Syzigy

This chess-like game is played on a round board consisting of 157 circular spaces, connecting both circularly (around the board) and radially (from the outside to the center). The outer rings connect all the way around circularly, but the inner rings have gaps, requiring more complex routes to navigate.
Each player has 7 Sages, 4 Stouts, and 4 Royals (one of which is the Czar). The Sages move 5 circles, and may only capture Royals/Czars. The Stouts move 4, and may only capture Sages, and the Royals/Czars move only 3, but may capture Stouts and Sages.
Capturing requires landing on an appropriate opponent piece. To win, you must capture your opponent's Czar, or all of either his Sages or Stouts.
