To match a cat:
Step 1: Choose a tile with a cat.
Step 2: Look for another tile that has the same cat.
Step 3: Click both tiles.
Step 4: Both tiles will disappear! (This is a good thing.)

Now if you cannot complete Step 3, I have some bad news; you done messed it up! Go back to Step 1 and find another cat. If you don't know what a cat looks like, do a Google image search.
Tip: Be sure to search by the word "CAT", otherwise you may get some unexpected results.

Once you have matched one cat, you will need to match more cats to win.
Hint: There are a lot of cats.

When there are no more tiles, YOU WIN!

For the Pros:
Heads up, this game likes to mess with you and put caterpillars in too! Do not be confused. To get rid of the caterpillar tiles, match them with other caterpillars.

Good luck and godspeed,
