Before you begin

Both players know the value of C.

The players know C, but you must determine which values produce the stated outcome. Treat C as a whole number: 0, 1, 2, 3, and so on.

Method Backward induction = rollback Start at the final decisions and work back to Player 1’s first move.

Game tree

Roll back every decision point

Player 1 Player 2

Use the tree as a scratch pad: click an action or terminal payoff to highlight it while you work. Click a different choice to change your mark, or use “Clear tree” before checking another value of C. At each endpoint, the first payoff is Player 1’s and the second payoff is Player 2’s. Scroll sideways if needed, or use “Center tree” to return to the initial decision.
