## Requirements

This document covers the basic hardware and software requirements to play Colossus. If you want to rebuild the game, please check the document Building Colossus .

Colossus should work with any Java Runtime Environment (JRE) or Java Development Kit (JDK / J2SDK) release 1.4 or newer. Using the latest (currently 1.4.1) is recommended. Building Colossus contains the links to the various JDK and JRE available.

On the hardware side, you'll need a color display (the higher the resolution the better, below 1024x768 is likely to look ugly) and enough RAM (64 MibiBytes should work, 128 MiB or more is better). A fast processor makes the game more comfortable, but as Colossus is turn-based, not real-time, it should work on about anything. For x86-family (i.e. Intel Pentium, AMD Athlon, etc.) processor, a speed of at least 200 megahertz should allow the game to run decently.

Finally, Colossus uses TCP sockets to communicate between client and server, even for local games . So if you have an old operating system that doesn't install networking by default, you may need to install it.

Colossus is free, so if in doubt, just try it.

The table below lists some tested configurations.
