FREEP: Higher or Lower? So Simple, So Addictive

About Freep, from BoardGameGeek:

FREEP is a push-your-luck card game in which players try to collect as many cards as possible by predicting whether the next card will be higher or lower than the previous one. On your turn, reveal a card and choose "Higher" or "Lower" before revealing the next one. If your prediction is correct, you may stop and keep the cards you have revealed, or continue taking risks. If you make a wrong prediction, you lose all the cards revealed during that turn. When two cards of the same value appear consecutively, you immediately keep that pair and continue playing with the remaining cards. Cards lost during failed turns are placed in a separate pile. When the main deck runs out, this pile is turned over without shuffling, so the cards return to the game in the same order. Special cards and the possibility of claiming another player's failed turn add further decisions and opportunities. The game ends when the deck can no longer be played. The player who has collected the most cards wins. -description from the designer
