oh god, winner list...long list is long.
Some of there were really crap with the broken english, #6.
"Today they say, that they both were lying yesterday" which implies that each of them separately said that both were lying yesterday. Which has no solution.
Also #15, that might be regional convention for the reasoning. Maybe somewhere the reason doesn't apply. It sure works in the US though.
And i didn't really know #17...i cba to do the cryptogram and gave up on that.
Stupid "think you're smart?" puzzles. LANGUAGE BIAS!!! When combined with broken language, it fails even worse!
