A logic puzzle invented by a 12-year-old boy

Find out what color everyone is wearing elfhow many liars are among them and who exactly is telling a lie.

1. Suppose Virtana is a liar. Then from statement 2 it follows that the elf in green is not a liar, but from statement 9 - that Virtana is dressed in green. But if Virtana is in green, statement 2 becomes true. This contradicts the assumption that the elf is a liar.

So Virtana is not lying. From this we conclude that she does not wear a green tunic, but one of the elves does.

2. Virtana speaks only the truth. Hence, from statements 6 and 10 we can conclude that Tinsel also speaks the truth. From statement 3 it follows that Tinsel is dressed in blue, from statement 7 - that one of the elves is wearing yellow. It turns out that elves wear tunics in yellow, blue, red and green.

3. We know that no elf wears pink. Therefore, from Statement 5 it follows that Mnement is a liar, which means that replica 8 is also a lie. It turns out the elves who tell the truth, - this is Virtana and Tinsel, and Mnemont and Glarald are lying.

4. Tinsel is wearing a blue tunic. Virtana doesn't wear green. From point 1 it follows that Mnement does not wear green either, so Glarald is wearing a tunic of this color. From Statement 6 it is clear that Virtana cannot wear red, she does not play curling. Therefore, Virtana wears yellow, and Mnement wears red.

It turns out that Tinsela, the elf in blue, won the curling championship by Mnement.
