Hercules Dominoes, Second Edition Level Starter

Hercules is the strongest man in the world, but one day he does something very bad. The priestess at Delphi tells him: 'The gods are angry with you. For twelve years you must work for King Eurystheus, and do twelve tasks for him. When you finish, the gods can forgive your crime.' Some tasks are easier, and some tasks are more difficult. Can Hercules finish all twelve of them? And what happens when he does?
