Here's a fun game. The backstory: your friend has started vim because of some unfortunate environment variable settings, has typed some keystrokes and now needs your help to exit vim.

Player A suggests a sequence of keystrokes that supposedly works.

Player B explains why that sequence doesn't work. For example, if A says "esc colon q ! enter", B can counter with "your friend was in insert mode and had pressed ^V".

I thought the shortest winning sequence had seven keystrokes but it turns out it wasn't enough.
