Infinite Tic Tac Toe

A nostalgic yet new evolution of the Tic-Tac-Toe!
Simple but deep, slightly unusual Tic-Tac-Toe.

This Tic-Tac-Toe has taken in two new systems, the "fading marks" and the "match point".
- "fading marks"
Only three marks can be put for each X and O.
When the 4th mark is put, the oldest mark disappears.
- "match point"
A player gets 1point if three marks align, and the game continues until either gets the match point.

The addition of these rules has evolved into a simple yet very deep game.
Two people can also play using the same device.
This is a game that can be played easily in a short time.
