'''Ryanmen''' {{kana|両面}}, | '''Ryanmen''' {{kana|両面}}, sometimes referred to as an "open wait", is the most common [[machi|wait pattern]] in the game. It involves two consecutive numbered tiles, waiting on either "outside" number. For example, a "34" needs either a 2 or a 5 in order to form a [[sequence]] of either 2-3-4 or 3-4-5. A ryanmen cannot be formed with [[terminal]] tiles. It is, by far, the most efficient wait pattern: it waits for 8 tiles (of two types) while only using 2 tiles. | ||

All other basic wait patterns can wait for a maximum of 4 tiles - ryanmen is twice as big. | *It is the most powerful of the basic waits.
