What is a tier in golf?

Definition

A distinct elevation level or plateau on a putting green that creates different putting zones and strategic considerations for approach shots and putting. Tiered greens feature multiple levels connected by slopes, requiring golfers to carefully consider pin position and approach angle to access the correct tier. Missing the wrong tier can leave extremely difficult putts with severe breaks and multiple elevation changes. Green designers use tiers to add strategic complexity and visual interest while creating risk-reward scenarios for aggressive pin-seeking approach shots versus conservative center-green targets.
