Backgammon Kifu Viewer/Editor Backgammon Kifu Viewer/Editor
This app allows you to replay backgammon games from game records, and to input and edit game records.
Previously, I offered three separate apps: replaying games from game records, inputting game records while watching videos, and editing game records output by kifu.me.
I have now integrated these apps into a single application that allows for playback, input, and editing.
Please run this app on a computer with a mouse. It will also run on touch devices such as smartphones and tablets, but it may not function correctly.
• As a game record viewer: You can load backgammon game record files and watch the game played out step-by-step on the board.
• As a game record input app: You can input game records based on dice rolls and operations on the backgammon board.
→ This app is intended for transcribing game records from videos, etc.
→ While eXtreme Gammon 2 (XG) also has a game record input function,
This app was developed with the aim of providing a tool that is specialized for game record input and easier to use than the XG's game record input function.
• As a game record editor: You can load a game record file and edit a part of that game record.
→ This app is intended for editing backgammon game record (kifu) from the text files that kifu.me outputs.

• If you load game data containing illegal moves into XG, XG will reject it. So it is best to adjust the dice rolls or other methods to avoid illegal moves.
• If you notice an input error and want to correct it, go back to the game record table of the position you want to return to Press button and re-enter the information from that point.
