How to play
Petzoong is a 2D top-down puzzle game based on Mahjong that you can play with just the mouse. To select a title, move the cursor over to it and click the Left Mouse Button. You can also do this to interact with the UI on the left side of the screen. The goal of each level or puzzle is to match all the tiles together until none remain. Your score will be determined by how fast you clear the tiles as indicated by the star timer on the right of the screen.
Each level arranges a number of tiles in layers. Each tile has an animal on it and you simply need to pair them with a matching tile. Upon making a match, the tiles will come together before leaving the area. The challenge is that tiles can't be blocked when making matches. Each tile needs to be open on either its left or right side. If they're only open on the top or bottom, they can't be matched.
If you're stuck, you can use the two powerups on the left side of the screen to help. The top one provides hints as to any currently available matches. The bottom causes the tiles to be reshuffled so that you can gain a new perspective.
