Free, freeware or open source: what is the difference
Three terms that sound alike but mean different things, and what each one lets you do.
A free game is one you do not pay to play. That does not mean you may share or modify it, and some free games include ads or in-game purchases.
Freeware is software or a game the author distributes at no cost while keeping their rights. You can usually download and play it, but not sell or change it without permission.
Open source means the source code is visible and the licence lets you view, change and share it under certain conditions. Common licences are MIT, GPL and the Creative Commons family.
Why this matters to us: the site only hosts games whose licence allows it. A freeware game that may not be redistributed will not appear here even if it costs nothing.
What to check before downloading a game: who the author is, which licence is stated and whether there is an official site. Those three details filter out most problems.
