Dooz

Overview

• Dooz is a comprehensive Tic-tac-toe application engineered for Android using Kotlin and Jetpack Compose.

• This project focuses on providing a modern, responsive user experience while offering flexible gameplay modes.

Technical Architecture

• Framework: Built exclusively with Jetpack Compose for a declarative, reactive UI.

• Design System: Implements Material3 design components with support for Dynamic Color, ensuring the application interface adapts seamlessly to the user's system theme preferences.

Game Configuration

• Grid Customization: Supports a dynamic board size ranging from 3x3 to 9x9. Larger grids are restricted to maintain playability and usability on mobile touchscreens.

• Difficulty Settings: Features three distinct AI difficulty levels (Easy, Medium, and Hard) to accommodate players of all skill sets.

Gameplay Variations

• Simple Game: A classic implementation of the 3x3 Tic-tac-toe variant. Two players compete to align three marks horizontally, vertically, or diagonally.

Artificial Intelligence Strategy

The AI behavior is governed by specific logic derived from the research paper, Flexible Strategy Use in Young Children's Tic-Tac-Toe by Kevin Crowley and Robert S. Siegler.

1. Hard Difficulty:

• Employs a prioritized heuristic approach rather than a traditional search algorithm like MinMax.

• The AI evaluates moves in the following order: Win, Block, Fork, Block Fork, Center Play, Corner Play, and Side Play.

2. Medium Difficulty:

• Utilizes a probabilistic model where the AI effectively flips a coin for each move, choosing between a random selection (Easy) or the deterministic heuristic logic (Hard) with a 50/50 split.

3. Easy Difficulty:

• The AI ignores strategic priority, instead selecting a random available cell on the board for every turn.

FAQ

Q: Which UI toolkit was used to develop the interface for Dooz?

A: The entire user interface is built using Jetpack Compose. By leveraging a declarative and reactive UI framework, the application ensures that the board state and visual elements update seamlessly as the game progresses.

Q: Does Dooz support themes that match my system settings?

A: Yes, the application implements the Material3 design system, which includes full support for Dynamic Color. This means that the UI will automatically adapt its color palette to match your Android system’s theme preferences.

Q: Can I play on boards larger than the classic 3x3 grid?

A: Absolutely. Dooz allows for dynamic grid customization, enabling you to choose a board size anywhere from 3x3 up to 9x9. The developers have capped the size at 9x9 to ensure that the game remains playable and ergonomic on mobile touchscreens.
