Goods Master 3D Online is a sorting and match-3 simulation game that focuses on tasks completed by grocery store stock clerks. The game displays wooden cubby-style shelves filled with mixed-up goods from different departments, including beverage and food items, health and beauty products, sports gear and toys. During timed play, the player must rearrange these items on the shelves into groups of three identical goods. Every time they make a valid match, the game removes the items and awards points.
The player needs enough empty spaces on the front row of a shelf to align the three items. Yet, not all shelves have enough empty spaces. The cubbies also contain several layers of items, with hidden goods behind the front rows. As a result, the player must rearrange items between shelves to both open up spaces and reveal the hidden goods that the game displays as gray shapes.
Goods Master 3D offers the player two main boosters. A yellow light bulb icon on the left side allows the player to auto-collect three items. They can temporarily freeze time with a snowflake item on the right side.
If the player runs out of moves, they can use coins to continue to play. They can also buy boosters with coins at the shop. They earn extra coins with multipliers at the end of each level, ad viewing and a lucky spin wheel. The latter rewards the player with boosters as well.
