The Game of Fif

This is a two person game. You play against your computer. The board consists of a row of nine squares numbered 1 through 9. Players take turns selecting squares. The goal of the game is to select squares such that among those selected by a single player there will be a triplet that sums up to 15 (hence the name Fif.)

If the box "I move first" is checked, you have to click the "Start" button which will cause the computer to make the first move.
