“Chronos is a game of Time exploration for 3-5 players, inspired by Lloyd Krassner's Time Line.”

The game is built on a Time Map made up of square tiles. Each tile is named for an era (Prehistory, Renaissance, Near Future, etc.) and has three values marked on showing its position in the overall timeline, the number of victory points gained for control of the era, and how resistant the era is to control. Every player has three units, a Leader, Agent, and Explorer. Leaders and Agents are used to gain control of uncontrolled eras. The game ends when a player has 22 victory points. A shorter Easy Game scenario is also included.
