What are they?

Logic Level 2

On an island you find knights who always tell the truth and knaves who always lie. You ask someone called Jack what they are and he reply, "I'm a Knave" Is jack a Knight or a Knave?

The statements conflict with each other , thus it is impossible to determine what Jack is.

Doesn't impossible to tell imply that Jack could be one or the other? But here, we can confirm that Jack can't be either one!

If Jack's a knave, then Jack is actually a knight. But if Jack's a knight, then he's a knave.

Therefore, the answer is: Impossible to tell

It's not impossible to tell. It meens that he neither knight nor knave. But that contradicts rules.

I’m going to assume that Jack migrated from a different magical island and that he is in fact a joker.
