PART 2 • Exploring the chess puzzle control panel

A green circle on a button means that this is a set we ' re allowed to try solving. If we look at the sets for a higher-level group:

• Let ' s roll the mouse over the button labeled“ basic” and see what we can learn from the description pane:

We learn that this puzzle set involves basic moves, that there are seven puzzles in the set, and that we ' re given sixty seconds to solve all seven puzzles( not sixty seconds per puzzle). The last line in the description pane shows that this puzzle set hasn ' t yet been solved by this user, so no award was given( that ' s why it says“ None”).
