Catch The Fruits

A small reflex game built with Kotlin for Android. Catch the fruit that appears randomly and reach the highest score in 10 seconds.

Overview

• Single-screen arcade-style game
• 3x3 fruit grid with random visibility every 500 ms
• 10-second countdown game loop
• Score tracking and replay dialog

Modernized Tech Stack

• Kotlin (Android)
• Android Gradle Plugin 8.5.0
• Gradle 8.7
• Data Binding
• Material 3 theme
• ConstraintLayout + GridLayout

Project Structure

• app/src/main/java/com/halil/ozel/catchthefruits/MainActivity.kt - game loop, score logic, timer, replay dialog
• app/src/main/res/layout/activity_main.xml - UI with Data Binding
• app/src/main/res/values/strings.xml - localized UI texts and formatted strings
• app/src/main/res/values/styles.xml - Material 3 app theme

How the Game Works

1. Game starts with score 0 and time 10.
2. Every 500 ms, all fruits hide and one random fruit is shown.
3. Tapping visible fruit increases score.
4. At the end of 10 seconds, game stops and replay dialog appears.
