iWARSIM is designed for playing wargames online. You can play the game alone or play with anyone connected on Internet.
Each wargame is provided as a separate module file. By loading modules, you can play any kind of wargame. For the current version,”Breakout: Normandy” and “Anzio” are provided as your testing module file.
From version 1.0, you can create your own wargame from scanned images just by dragging and dropping them on the iWARSIM’s map window. Once you drop image files, you are ready to play.

The advantage of iWARSIM is in it’s rich functionality and intuitiveness. I spent about eight months to develop the user interface alone.


Click and drag units over the map. iWARSIM will keep track with any complex move (combinations of movement). Yellow arrows indicate the course of the movements.

There is no recording button, for all of your movements of units are automatically recorded. Using the “Playback” pannel, you can playback the game when you finish it, or even during game play.

Relational-database is the core architecture of iWARSIM. “Save Play as…” allows you to save the gaming session on your hard disk. You can stop the game any time and play it back at any time.

You can share your movement data with any opponent players via FTP, e-mail, or USB storage device, When you click the”Out-going” button, the latest unsent data will be transferred to a predetermined location.

Unlimited numbers of Undo
There is no limit to the number of Undo’s and Redo’s. However, once you transfer data to your opponents during the session, all of your Undo data will be erased in order to prevent discrepancies. You can’t undo roll of dice, too.

iWARSIM uses only two file types. They are a game-module file (.gme) and a play file (.ply).
The game-module file is where the map board, counters and scenarios are stored. The play file stores not only the current status of the game but also all “history” including yours and any opponent players’.

Bug report button
Quick to send bug report to me.
