Coffee Master Idle is a semi-idle time-management simulation game. It tasks a player with setting up and managing a coffee shop via an avatar. When they make the shop prosper, they can expand their business to other types of caf�s.
The player receives an initial start-up fund to open the shop, set up a cash wrap, and start selling beverages to customers. After they make enough money, they hire a cashier, open a human resources office, and perform upgrades to each character's speed and capacity. Eventually, they can unlock additional tables and furnishings and offer more menu items. If they do well, customers display happy smiley face emojis. If they perform poorly, customers display angry emojis and leave the shop.
Coffee Master Idle requires the player to direct their avatar to various areas to collect payment. The player then directs the avatar to spots on the floor marked with cash amounts to transfer money and reveal hidden things locked in those areas. The game also displays floating temporary boosters now and then, including a cash magnet and free money. That said, the player must watch advertisements to use them. The game also offers a lucky draw wheel that supplies money and items.
