On the left panel you can see the queries and the types. The queries are the entry points to the graph and the types are all the return objects.

To make your first query select one of the queries, for example the bookies. On the example section you will see a query sample. On the left side you can see the query and variable tabs. You need to copy both of them and paste into the playground. To copy them you can use the first button on the right side. You can also add more levels to the query(+ and -). You must paste the query into the playground query section, and the variables into the playground variables section.
