This domain used to run on Flash.

Years ago, this site hosted a library of Flash games. Then Flash died — Adobe shut it down in 2020, and every browser on earth stopped running it. The games didn't disappear because anyone wanted them to. The plumbing underneath them just stopped existing.

Rather than dig up old files that were never ours to relicense, Kaja Games is starting over: every game here is built from the ground up, original code and original art, so nothing on this site can expire twice.

Some games are quick arcade sessions. Others are built to teach you something real — actual distances, actual sizes, actual facts — without feeling like homework. Both kinds belong here.
