A normal hand needs four tile groups and a pair - thus, it needs five blocks. The goal of five-block theory is to identify a hand's blocks, and try to improve the weakest blocks. | A normal hand needs four tile groups and a pair - thus, it needs five blocks. The goal of five-block theory is to identify a hand's blocks, and try to improve the weakest blocks over having a 6th block. In other words, prefer having five strong blocks rather than six blocks. | ||
When four blocks are complete (e.g. three tile groups, one pair), a hand will be in [[tenpai]], where the hand waits to complete the fifth block. Since the weakest block is likely to complete last, and a hand in tenpai waits on the last block, it's best to improve the weakest block first. Also, identifying blocks can help with identifying tenpai. | When four blocks are complete (e.g. three tile groups, one pair), a hand will be in [[tenpai]], where the hand waits to complete the fifth block.

South 4, or "all last", is typically the last hand of the game (barring [[renchan]] or not reaching target score). Many mahjong rule sets, particularly tournaments, apply a calculation of [[uma]], a point bonus that depends on placement. Therefore, even a 100 point lead over an opponent can result in a big bonus. | South 4, or "all last", is typically the last hand of the game (barring [[renchan]] or not reaching the target score).

In this last rotation, players must take note of point differences. For non-dealers, this is effectively the game's last hand. When scoring a hand, the player must take note of the point difference via both ron and tsumo. From there, the hand must be built to fit the point requirement to make up the difference for gyakuten. | In this last rotation, players must take note of point differences.

Players who plan to play the game offline should learn game etiquette. Etiquette aids in game functionality, by prompting players to not waste time. A single hanchan can take roughly anywhere between one hour to ninety minutes, depending on the average player speed. | |||
