The ‘logic puzzle’ element of Gigacrawler seems to be too easy.
I had a couple of ideas of how to change it:
i) Have 5 cities instead of 3: 2 always lie, 2 might lie or tell the truth, and 1 always tells the truth and is the one you’re after.
ii) Don’t have set locations for the temples: instead you have to wander around and find them.
Obviously I could always abandon the logic puzzle idea altogether.
Please let me know what you think.
