Hi Lolly! HiLo is a well known cards game with simple rules. You must guess, if the next card will be Higher or Lower than previous. Your opponent also makes her choice. If you guess correct and your opponent wrong, you go to the next level. But if you are not right, and your opponent is correct, you go level down. Each next level the girl takes off her next clothes. So, just a bit of luck, and you'll get her exciting show!
