Lan-Pan is a board game I made similar to Tic-Tac-Toe and Checkers. Players take turns moving their pieces to trap and capture each other. The rules are simple:
Rule 1:The 2 players' pieces are on opposite sides of the board. Either player may move first. Each turn only one piece is moved. Pieces may move immediately up, down, left, right, or diagonally, but the corners of the board may not be moved to, intentionally.
Rule 2: To capture an opponent's piece, one of your pieces has to be able to move one square diagonally around/past it. For example, if a white piece borders a black piece, and it's white's turn, white can capture by moving in a manner such that it borders a different side of the black piece's square, then black's piece is captured. The last one with all their pieces captured wins.
Rule 3: You can forfeit a turn by saying "I stall." Stalling forces your opponent to make a move, but you can't stall 2 of your turns in a row.
Rule 4: When each player only has one piece left, two moves can be made each turn, including moves that could also be made in one turn, but not moves that undo each other. For example, in this stage you may not move a piece forwards and then backwards. Also, in this stage you are not allowed to stall.
And that's the default ruleset! If you're interested, you may try other setups of the game's board, or giving more or less pieces. Terminology and notation is still being made for different positions, rules, and techniques in the game. Or, you can play using the default ruleset on this computer version I made in Scratch.
