# Dooz (open-source game)

> Dooz is a free, open-source game for Android. A Tic-Tac-Tao clone, a simple pen-and-paper game. It has 107 GitHub stars and is released under the GPL-3.0-only license, and you can install it from F-Droid.

I created this implementation using Kotlin and Jetpack Compose for Android devices. Features Technical Jetpack Compose Material3 and Dynamic Color Game Variable game board grid size from three-by-three to nine-by-nine (Larger than nine-by-nine is simply ridiculous and unplayable in mobile phones) Variable game ai difficulty (easy, medium, hard) Variations Simple Game The Simple game is the most simple variation of Tic-tac-tao with a three-by-three grid with two players. The player who succeeds in placing three of their marks in horizontal, vertical, or diagonal is the winner. Simple Game AI Currently, in hard mode, AI uses a strategy rather than an AI search algorithm like MinMax.
