Play the online game "Monkey GO Happy 6" by clicking on different areas of each level to obtain hidden items, then use those items to interact with other elements of the environment. The goal of each level is to complete different tasks and make the monkey happy.
The game begins with a short tutorial that demonstrates how to identify special items in the environment and click on them to add them to your inventory, as well as how to drag the items out of your inventory and use them to interact with the level. You are then able to customize your monkey character by putting on different hats. Once you choose your desired hat, you need to move to the main menu and select a level. Only one level is available at the start of the game, with subsequent levels unlocking as you play.
Each level features a different objective in order to make the monkey happy and unlock the next level. In most cases, the objective becomes clear by interacting with the game world. For example, the first level includes an interactive item in the form of a fish in a bag. When you click on this item and add it to your inventory, it becomes clear that the fish needs to be placed in the open hole in the ground.
