When I was playing UNO earlier, I found two strange cards: they were purple and blank, with no number or special sign on them. What is this card for? Is it like a Wild Card or +4 Wild Card? It wasn't mentioned in the instructions.

These cards are mentioned in Uno instructions — you can use one if you lose or damage one of the other cards, or you can use it to include custom house rules card into the deck. See reference in manual:
What Are These Extra Cards For?
Blank Card - This is a special card that you may use in one of two ways. If a card from your UNO deck is lost or damaged you may use the Blank Card as a replacement. Example: If you find that your deck is missing one of the yellow 7's you would simply replace it by taking the yellow Blank Card, marking a "7" on it and adding it back into the deck.
If you family has a special UNO rule you prefer to play with you may write that rule on the Blank Cards and add them straight to the deck
It says also that you should have 4 of these; maybe you have lost the other two?
