The facts on the card
The card carries these facts from its Wikipedia article.
- Adjacent means that two regions share a common boundary of non-zero length.
- It was the first major theorem to be proved by use of a computer.
- Initially, this proof was not accepted by all mathematicians because the computer-assisted proof was infeasible for a human to check by hand.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Four color theorem article was read about 160,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 77 and blocks with 74: each hit it takes is cut by 30 %.
How to get Four color theorem
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
