Caesar's Game

Caesar's Game is a 1984 game by Malcolm Goldsmith and Michael Kindred, published at Waddingtons.

Each player has four columns and six coins. This is the initial setup:

Notice that coins are placed in the small square intersections between the large circles.

Rules:

• On his turn, the player either moves one of his columns or one of his coins
• A column at the board's edge can move to an adjacent empty circle of its color
• Inside the board, columns jump over adjacent coins, landing in the immediate next circle, that must be empty; jumps can be multiple
• Coins can move to diagonally adjacent intersections, that must be empty
• Coins can also trap enemy columns by custodian capture; a trapped column is then placed at an empty circle (of its color) at the board's edge 
• A column can pass through a 'trapped' circle (i.e., between two enemy coins) but cannot end its movement there
  
• Wins the player that makes a square formation with his four columns, no column can be at the board's edge
