4 CYTE (Foresight) (1962)

Each player has an identical set of letters and a six-by-six grid. Players alternate calling letters and placing them on their respective grids. Each player may hold one letter as a stand by.

When the grids are filled, the players score the six rows, six column and two diagonals. When a player has spelled a word that is at least three letters long that player receives points for that scoring line. Longer words are worth more points.

The player with the most points wins.

In the solitaire version, a player selects thirty six letters and moves them around at will to score a personal best.
