Kobold Crawl

This game includes a few dozen rooms presented in a random order. You're given a menu of options, which often invite you to take a risk to get greater reward. Most of the rooms have a joke or a clever word or two.

You'll probably lose at least once, but when you continue play after losing, the game will present you only rooms you haven't seen. I won on my second try after doing that.

With persistence and just a little luck, you'll probably get to the bottom in well under an hour.
