ICE quiz: 3 questions
Three questions on the ICE card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
The key-dependent bit ______ is implemented efficiently in software.
Answer
permutation. The key-dependent bit permutation is implemented efficiently in software. From the ICE article on Wikipedia.
In which decade?

Answer
1990s. In cryptography, ICE is a symmetric-key block cipher published by Matthew Kwan in 1997. From the ICE article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
ICE. ICE 43 · Addition reaction 39 · Saviem H 33 · Kalia 21 ATK in WikiCards.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- The algorithm is similar in structure to DES, but with the addition of a key-dependent bit permutation in the round function.
- The key-dependent bit permutation is implemented efficiently in software.
- The ICE algorithm is not subject to patents, and the source code has been placed into the public domain.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The ICE article was read about 2,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 43 and blocks with 9: each hit it takes is cut by 4 %.
How to get ICE
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.
