4. 4

   Click the 'Remix' button to make your own copy

   
5. 5

   Start by clicking on the 'Dogs' sprite.

   This sprite contains costumes for 10 different dogs.

   
6. 6

   Add this code to hide the sprite and set up the 'Dogs Seen' list.

   We will use clones to show the dogs on the stage.

   
7. 7

   Next, add this code to create a new clone every second.

   A clone is a copy of a sprite.

   
8. 8

   To be able to see the clones, we'll need a bit more code.

   This will send the dogs to the left side of the stage and give them a random costume.

   
9. 9

   Press the Green Flag. Can you see dogs appearing on the left?

   
10. 10

    To make the dogs move, add these blocks.

    The dogs will disappear once they cross the stage.

    
11. 11

    When we click a dog, this code will check if we've seen that type before.

    
12. 12

    If we haven't, then that dog's name is added to the list!

    
13. 13

    Test out your code.

    Can you see the types of dogs being added to the list as you click them?

    
14. 14

    Finally, let's add some code to check if we've seen all the dogs.

    There are 10 dog types, so we'll have to check if our list has 10 items in it.

    
15. 15

    If we have seen all the dogs, then we win and the game stops.

    Can you spot all the dogs and win the game?
