Preloaded are a creative studio who have made some great online educational games for other websites, and you can find them all in one place on their own site.

For example science teachers might be interested in Wondermind which is a game about the brain/neuroscience written for Tate Liverpool, inspired by the works of Lewis Carroll.  Thingdom is a fun science game written for the Science Museum which I’ve written about on the blog before.

There are also some great historical games such as High Tea and 1066,  as well as games helping teens understand mental health and complex issues such as death (The End). Plus many more
