Further information and support

Minimum specifications are listed on each of the games main pages as a guide.  We cannot guarantee performance if your computer does not meet these requirements, but as most of the titles are free you can still try them.  But please try a demo version before making a purchase of a non-free title.

For those games that support a gamepad, please ensure that it is plugged in before running the game, otherwise it will not be detected and you won't be able to use it until you restart the game.

PC (Windows) information

All of our games have been tested on Windows XP, Vista and 7, so should work without any issue.  For those running Windows XP, please note that you should have DirectX 7 or later (Vista and later already have a later version installed).  You can check this by going to Start > Run... and typing "dxdiag".  The version of DirectX will be displayed at the bottom of the first page of information.  The latest version can be downloaded from the Microsoft web site (search for "directx 9" and a link for this will be under the Downloads heading, probably "DirectX 9.0c End-User Runtime").

Please note that some anti-virus software reports our installers as containing malware.  This is a false report and can be safely ignored (we have scanned all of our installers before upload to ensure they are safe).

Additional information for Windows 10

If you experience any problems getting the games to run under Windows 10, you may have to run the installer as administrator and under a relevant compatibility mode.

First, set the compatibility mode for the installer itself by right-clicking on the application, going to Properties and the Compatibility tab.  Check the box to run in compatibility mode and select Windows 7 (you will need Windows XP Service Pack 3 for Attack of The Smilies, Othello and Rockfall - The Return).

Then run the installer as administrator, which can be found by right-clicking on the application and selecting this option.

Once installed you can try running the game.  If this fails you will also need to set the same compatibility option as you did for the installer.  You will need to find the main game application and follow the above steps.  By default, the games are installed in C:\Program Files (x86)\SOS Software.

Should you have any difficulties please get in touch and we will do our best to help.

Mac (OS X) information

All games available for the Mac have been tested on OS X 10.4 (Tiger) up to 10.7 (Lion).  There are versions available for PowerPC and Intel based Macs, so please download the correct version for your Mac (10.7 or later are Intel only).  There may also be a Universal version that will work on both types of Mac.

All Mac software comes in a compressed disk image format (DMG).  Once downloaded, double-click on the file to mount it as a disk.  Open the disk and drag the game's folder to your Applications folder to install the game.  You can then unmount ("eject") the DMG.

Inside the game folder there will be the executable for the game, as well as a "read me" or "instructions" file containing details on how to play the game.
