My personal favourite is an old version of Larry Parker’s Hangman 1.0 that used to be freeware and/or $15 US shareware. It’s an old dos desktop game from the late ’80s (I think) for VGA. But it has six word lists to choose from, all of which can be edited – by learners, quite easily – to create individualized spelling lists. (Putting it on multiple classroom desktops yields even more lists.) The hint function – which can also be edited – avoids the difficulty of words-without-context.

There are many other versions of hangman out there, but I’ve never seen one that was as flexible. Sadly, like many great DOS driven learning or text-based games – remember interactive fiction!?! – it seems impossible to find on the web nowadays.
