Janken is a beautifully designed, modern, privacy-first Rock-Paper-Scissors and RPSLS game for Android, built natively with Jetpack Compose.

Whether you are settling a debate with a friend or sharpening your mind against adaptive AI, Janken delivers an exquisite, fluid, and delightful experience.

✨ Key Features

• 🤖 vs Computer (Smart Bot AI): Play against 3 distinct difficulties (Easy, Medium, Hard). The Hard AI analyzes your patterns with Markov chains to counter your tendencies!
• 👥 Pass & Play (Local 2-Player): Play with a friend on a single phone with true privacy! Player 1 chooses a move which is instantly locked and shielded before handing the phone over to Player 2.
• ⚡ Quick Decision Mode: Solve everyday dilemmas instantly — "Who gets the last slice of pizza?", "Who pays for coffee?", "Who takes out the trash?"
• 🦎 Rock-Paper-Scissors-Lizard-Spock (RPSLS): Expand your battles with the classic 5-move variant! Includes an interactive visual rules cheat sheet.
• 📊 In-Depth Statistics & Match Logs: Track your win rates, winning streaks, move distribution breakdown, and review detailed match histories.
