In Ohio all players start with an identical hand of cards, numbers 1-10 plus one 'Ohio' card. After the lead, on your turn you must either pass or play a lower card when everybody else passes, the last player to have played a card collects for purposes of end-of-game scoring the whole pile of cards (which for convenience will be called a trick) and then has the lead. The Ohio card is deemed always just a little lower than the last card played, so if a 2 is played and then an Ohio card (or two or three Ohio cards), a 1 would still be lower. When one person plays his last card, finish the trick and calculate the scores. Ohio cards count negative 10 all others their face value. Cards still in hand count negative (including Ohio card which is negative 10 if still in hand). Highest total wins. - BoardGameGeek
