I don&#x27;t think any kid--or adult for that matter--without experience in Forth would be able to figure this out. Even if they did, it wouldn&#x27;t teach them programming.<p>All I saw were stack manipulation puzzles. Granted, I quit at  the (oddly depicted) swap puzzle, so maybe it gets better, but I didn&#x27;t see any sign of that.<p>At a minimum, provide help, hints, points for passing a level, and some kind of roadmap of what I will accomplish if I finish the game.<p>Edit: If you want to find out more about Forth, here is a tutorial from the One Laptop Per Child site: <a href="http:&#x2F;&#x2F;wiki.laptop.org&#x2F;go&#x2F;Forth_Lesson_0" rel="nofollow">http:&#x2F;&#x2F;wiki.laptop.org&#x2F;go&#x2F;Forth_Lesson_0</a>
