Daily Scratchers are awarded every few days that you log on to the game - after 5 days, you get one scratcher and after 10 days you get another two. The cycle then re-starts.
They may also be obtained as rewards from daily scratchers.
They list 6 numbers, apparently in the range 1-20. One is the Winning Number, and the other 5 are your numbers. Each of your numbers is associated with a prize. Possible prizes include:
- 1 or 2 Energy Packs
- 1-star Uncommon Lieutenant
- 1-star Rare Lieutenant
- 1-star Epic Lieutenant
- 1 free Daily Scratcher
- 3 Stamina Packs
If the winning number matches one of your numbers, you win the corresponding prize. If it doesn't match, you still get a consolation prize. However, there are no consolation prizes anymore since the update done by Phoenix Age.
