Indoor Sports was developed by Kevin Blake & Jason Sobellis for DesignStar's SportTime and first published in the US by Mindscape in 1987 for the Commodore 64. It was converted to many other platforms, particularly in Europe where it was published by Databyte, Advance Software and Tynesoft (depending on platform).
This game simulates bowling, darts, ping-pong and air hockey. The C16/Plus/4 version only has the first 3 events.
