Patients are reminded not to die in the corridors.

ORIGINAL STORY 21/1/15 1.35pm: Medically dubious simulation classic Theme Hospital is now available to download for free via Origin.

It's the latest title in EA's regular 'On the House' promotion, which gifts freebies to Origin members every month or so.

Got an Origin account? Simply head to Theme Hospital's download page and nab it for free.

Once downloaded, the game is yours to keep forever.

Theme Hospital remains one of the best simulation games of the '90s. Developed by the now-defunct Dungeon Keeper developer Bullfrog, it mixes management and business aspects with the need to cure queues of patients struggling from bizarre diseases.

Truly, the first time you see someone enter the re-inflation clinic is a beautiful thing.

Previous titles in the EA promotion have included Dragon Age: Origins, Dead Space, Peggle and Plants vs. Zombies.
