Two-Player Makruk on One Device
Sit Together and Start
Put a phone or tablet between two people. There is no room to create and no connection to wait for. White moves first; after a move finishes, it is Black's turn. Agree in advance whether a mis-tap can be taken back. If you are keeping score, swap White for the next game.
Before You Start
Keep the device between you. The player to move selects a piece, then a destination; once the status bar changes color, the other person takes over.
For a first game, mention two facts: bia start on the third rank and promote on the sixth. Explain the short met and the forward khon when those pieces actually move.
Agree on takebacks before the first move. For a match, play two games and swap White.

See Whose Turn It Is
The status bar shows the side to move. Tap one of your pieces to see legal squares, then tap a destination to finish the move. Selecting the wrong piece does not count; pick another. Hand the device over only after the color changes.

Highlights Only Mean Legal
The usual argument is whether a piece can really go there. Met, khon, and bia all move shorter than their chess cousins. Highlights already apply those rules. A lit square is allowed, not necessarily good.

Each Person Starts One Game
In a single game, White always moves first. To keep score, play two games and swap White. The move list stores each from-to. If you disagree about when the khun was left open, replay from that point.
