Tile efficiency = how many tiles can complete your hand.

EFFICIENT SHAPES (keep these):

1. Pairs

• Need 2 more for Pung

• 2 tiles available × 3 suits/deck = many chances

2. Sequences (Chows)

• 4-5 can become 3-4-5 OR 4-5-6

• Two possible completions

3. Double-sided waits

• 4-5-6-7 can complete with 3 OR 8

• Maximum flexibility

INEFFICIENT SHAPES (avoid):

1. Lone terminals without pair

• 1-Dot alone needs TWO more 1-Dots

• Or 1-2-3, but you don't have 2-3

2. Isolated honors without pair

• Can't form Chow, need exact match

Efficiency rule: More completion options = better.
