Tile efficiency

Hand advancement may require the choice to discard from existing hand pairs.

The third chapter of the book covers tile efficiency with an emphasis on maximization. Players need to understand that a hand can be broken down into basic blocks. Given various hand shapes, a hand during the process of development always have a number of waiting tiles to further progress the hand. Here, player must look to aim to reduce the shanten count. A lower shanten count reduces the number of waiting tiles. This only means the hand advances and requires fewer tiles to advance further. Once tenpai, the counts are minimized.

Tile groups

Tile groups can be broken down into two subcategories: sequential and triplets. Of the two, the former is the easier to complete by virtue of greater tile counts for completion. For every waiting pattern, there is a set number of waiting tiles. Ryanmen provide the greatest number of waiting tiles from using just two tiles. As for other shapes, players may need to consider the ability for the tile shape to be reformed.
