There's something off in the javascript random tests. thought is always passed as a number, not a string, and every test expects ''

Great concept and very well-presented. I think parts II & III could be combined into a single kata (one that I look forward to trying), although the more performance-hungry among us might demand a separate kata devoted only to that.

You are nothing if not thorough ;) Appreciate the heads-up.

Got it, thanks.

I'm failing around 3% of the random tests. It's always on a potion that was provided to the Apprentice in the constructor but which is later unrecognized by the Alchemist in a process request. Are we meant to ignore them?

Superb. Reminiscent of Flotsam and equally fun to solve. Map ideas incoming :)

... furthermore, why in the world is each string in TABLE inside a list?

Excellent kata, as always!
- A couple of typos in the text for the sample tests:
definately => definitely & appartment => apartment

• No random tests.
• Probable duplicate without added complexity.

Should a cheesy solution like mine pass?

JS: Default problem of twoOldestAges the code is

C#: Tests of a random nature there are not

I'm in the same boat. I'm pretty sure I have the right formula but only pass around 30 large tests.
