Deduplicate - Mastermind/Bulls and Cows

[namedots]

I'm sure I'm doing this wrong but here are some arbitrary bullet points:

1. Mastermind Hint Pegs

• published March 2015
• higher quality
• more languages, including those of the other one
• 537 solves across languages

2. Bulls and Cows

• published November 2018
• 324 solves across languages
• broken English, slightly broken markdown
• class as user solution
• mixes strings and exceptions for errors

Mastermind and Bulls and Cows refer to roughly the same game, with Mastermind being the commercialized product.
