You have an option to run simple test games locally on your computer. To do so, download or clone the Local runner utility. Use of that utility will allow you to test your strategy in an environment similar to the environment of a testing game on the site, but without any restrictions on the number of games created.
Renderer for local games is much different from the renderer on the site. All game objects in it are shown schematically (no fancy models) according to their real size and form, which will probably allow you to better understand interactions between the objects. Creating of a local game is very simple: start Local runner with the corresponding script (for Windows or *nix system), then run your strategy from the development environment (or using any other method) and watch the game. You can debug your strategy using breakpoints during local games. But remember that Local runner waits for response no more than 30 minutes. By the end of this time it will consider your strategy “broken” and continue to work without it.
