Dooz or Tic-tac-toe is a simple pen-and-paper game. I created this implementation using Kotlin and Jetpack Compose for Android Devices.

Variations

Simple Game

The Simple game is the simplest variation of Tic-tac-toe with a three-by-three grid with two players. The player who succeeds in placing three of their marks horizontally, vertically, or diagonally is the winner.

Simple Game AI

Currently, in hard mode, AI uses a strategy rather than an AI search algorithm like MinMax. This strategy consists of these steps: Win, Block, Fork, Block Fork, Center Play, Corner Play, and Side Play.

Strategy's source: Flexible Strategy Use in Young Children's Tic-Tac-Toe by Kevin Crowley, Robert S. Siegler

More info on the strategy here

On Easy difficulty, the AI plays a random empty cell in the grid. In Medium difficulty, AI chooses between Easy and Hard Difficult for each move based on a 50/50 chance.
