On Everskies, there are two different ways to claim your daily reward, which is always either an item, or a random amount of Stars or Stardust.
The daily scratchy resets everyday at around 8:00-9:00 am CET. The only real difference between the two ways is the method of obtaining the reward which depends on the device you are using to play Everskies.
The Daily Scratchy is available only on the Web version of Everskies, and can be scratched once per day, unless you have Starpass; then you have 2 chances to win some goodies.
The Daily Spin is available only on the mobile version of Everskies, and can be redeemed once per day, unless you have Starpass; then you have 2 spins.
