Getting daily rewards is easy: simply log into the game every day. The more days in a row you do so, the better the reward will be.
If you log into the game 5 days in a row, you will receive one of the five parts of the Fortune Talisman. When you collect all 5 parts, you will get the Talisman that will increase your number of lives to 6 and restore each live 10 minutes faster for 10 days.
