seyahdoo/Okey-Unity ? reverse-engineered prompt

Build me a simple offline Okey game in Unity that feels like a real tabletop game.

I want to be able to start a match, shuffle and deal the tiles, play turns against computer opponents or just test the game locally, and finish a round when someone wins. Make the game easy to understand, with a clean board, tile dragging or tapping, and basic rules working correctly. It should run without any internet connection and be playable as a normal Unity game.

Please make the flow polished enough that someone can open it and immediately play, with sensible menus, restart options, and clear feedback for valid and invalid moves. If anything about the rules or setup is unclear, use current Okey references online and keep the implementation practical.
