Ultimate Tic Tac Toe
Tic-Tac-Toe within Tic-Tac-Toe
A variant of Tic-Tac-Toe where you play on 9 Tic-Tac-Toe grids at the same time. Whoever wins three small Tic-Tac-Toe grids in a row wins the large Tic-Tac-Toe grid. Each move on the small grid determines where the next move on the large grid can be made.
