Ohanami consists of a deck of 120 cards that are numbered from 1-120, with each card having one of four symbols on it. The game lasts three rounds, with players scoring at the end of each round, in addition to bonus scoring at the end of the game.
At the start of a round, each player receives a hand of ten cards. Each player chooses two cards, then passes the remaining cards to the left. All players reveal their cards at the same time, then decide whether to use 0, 1, or 2 of them in personal rows of cards. When you start a row, you can use any card; to add a card to an existing row, that card must be higher than the row's highest card or lower than the lowest one. A player can have at most three rows of cards. Discard any cards you don't use.
