In Wonder Crash Clicker you're on a mission to destroy all of the wonders of the world such as pyramids, the hanging gardens, and more. You do this by raining down a stream of projectile blocks that destroy the blocks making up the various structures you're attacking. You'll start by attacking houses and villages to build up your points, then use your points to buy upgraded attacks. The attacks are as follows:
Yellow - Your default attack
Red - Small but fast attack
Purple - Explosive attack
Green - Shatter attack
Turquoise - Bouncing attack
Pink - Vertical line attack
Gray - Horizontal line attack
Many of these attacks will happen at regular intervals but you can speed up your basic yellow attack by clicking the screen. This also allows you to aim it.
When you destroy enough blocks, you will get the opportunity to do a Wonder Trial. In this trial, you will have to destroy a wonder of the world within a certain time limit. There is no penalty for losing so don't hesitate to give it a shot if you think you can win. Destroying a wonder will give you a special currency called "talents." Use talents to unlock bonus features such as increased attack power and increased time to destroy wonders.
