Online Okey Game

PiPlayBox is a group project where game sessions are shown in 3D on a desktop and played locally with friends on mobile, with a Raspberry Pi server tying it together over web sockets. My part was the mobile side.

I enjoyed working with the desktop and server teams, but the mobile app was my responsibility: the UI (profiles, lobbies, the Okey game) and the logic behind it.

The UI parts I built

• Sign-in that works over the web sockets.
• A profile screen that loads each user's info and picture.
• Lobbies that show the game type and where players sit, up to four.
• Page and route management for the app.

I also wrote the whole multiplayer Okey logic from scratch in Flutter and Dart, without a game engine.

The multiplayer logic

• Every tile and rack, assigned to each player.
• Turns that start with an extra tile and pass to the right as it is tossed.
• Players wait for the active player's draw, but can still arrange their own tiles.
• Two separate game sessions running at the same time.

The game rules

• The joker tile that can stand in for any tile.
• Valid tile orders: repeats up to four, or runs of increasing numbers.
• End-game checks for the right order and spacing.
• Passing a tile to the right, and drawing from the left or the middle.
• The draw case when the middle is empty.
• Scoring from the tiles left on each player's rack.

The workload and the time were a challenge, but it was good practice. In an agile team I saw how much teamwork and communication matter, and I am grateful for the people I worked with.
