Numerical Tic Tac Toe:

Drag a tile with a number in one of the Tic Tac Toe boxes. The blue player plays with the odd numbers and starts. The red player plays with the even numbers.

There are three variants:

1. Only play with the numbers: the player who puts down 15 points in a line wins (sum of 3 tiles in a line)

2: Only play with the colors: the player who has three tiles of his color in a line wins

3. Play with numbers and colors: the player who puts down 15 points, or has 3 tiles of his color in a line wins.

The first variant was invented by the mathematician R. Graham. The second variant is the well-known Tic Tac Toe game. The third variant was invented by the mathematician PH Nygaard.
