Note (6/22/14): These rules and rules cards are a bit out of date. The rules can now be found here, and the new rules cards can be found here.
The current version of the Crazier Eights rules cards and rulebook can be found here. There are twelve rule cards, but all the main rules are in the rules summary card.
A PDF of the rulebook can be found here. (Right click save as.)
Let me know if there are any problems with the rule cards or rulebook.
Crazier Eights 
some typos / comments
rules summary – ‘all players draws’
rules summary – should read ‘controlled by the player who played them’…not plays.
Crazier Eights Rules (part 2) – the typical example is youngest goes first, but whatever.
Crazier Eights Rules (part 3) – ‘but the isn’t a card in the draw pile’ (I think you mean there)
Crazier Eights Rules (part 3) – this seems overly complicated. Can you just say the discard pile has only 1 card?
Crazier Eights Rules (part 6) – seems superfluous to mention ‘this version’ as they are already reading the rules for ‘this version’. Which begs the question, how are you going to differentiate versions?
Crazier Eights Rules (part 7) – should read – ‘cards can be played regardless of rank or suit’.
Crazier Eights Rules (part 7) – see remark about (part 2)
Crazier Eights Rules (part 8) – headache! Can you just say ‘Whenever 2 or more abilities would trigger at once, apply them in the same order as the turn structure’? You can specifically mention that the current player’s abilities happen first and then continue clockwise. When you get to the spot about multiple triggers by the same person, you could say ‘ the current player chooses which order to apply them’
Crazier Eights Rules (part 10) – use a concrete example…If a player would look at or reveal the top 5 cards of the draw pile and there are less than 5 cards in the draw pile…
If you read all of these as a whole, it seems a bit repetitive.
clarification – ‘Crazier Eights Rules (part 7) – see remark about (part 2)’ should be ‘Crazier Eights Rules (part 7) – see second remark about rules summary’
The corrections have been made.
Michael, thanks for the help. I will look into all this.
Begging the question is technically a type of fallacious argument, but I know what you mean. I think it is worth saying “this version” because the rules should be the rules for crazy eights no matter what version is played. It can also produce some anticipation for future versions of the game.
I don’t know if there will always be major ways to differentiate all the games other than the fact that the box will be different. “Crazier Eights II” could be on another box or “advanced crazier eights” for the advanced version. However, set symbols were already added to the advanced versions of the game.
