A downloadable game for Windows, macOS, and Linux

Stand-alone version of a trading sim module that's to be used in an upcoming project in development. This is a very slow moving trading game, it's best to let it run in the background and check your assets occasionally.

Set in an MS-DOS like environment, commands are to be typed.
Type COMMANDS for a list of possible commands.

how to reset the game?


Hi, great suggestion!

Version 1.2 has just been uploaded. After downloading it, you should  be able to enter the command RESET to completely reset the game.

Thanks for the feedback and thanks for playing!

I enjoyed the game, I'd recommend a command that changes the speed of the game and also upgrades or a shop that would let you buy computers to algorithmically trade for you. Cheers!


I may add some future updates eventually. In the end this game will be part of a bigger game as a kind of mini-game, so it's bound to change a lot until then. :)
