How do the Daily rewards work?

You can get a reward for logging in to the game every day. The new day is 00:00 AM. 

The game has a monthly cycle of daily rewards. Rewards increase in value. At the beginning of the month, the cycle starts over.

The amount of rewards is equal to the days in that month.

If skipped a day, simply get that (and only that) reward the next time you log in.

The Gift Box

There are about 3 boxes each month. Each time, you get one reward randomly with equal probability from the gift pool (1000 coins, 1000 coins, 2 gems, 2 gems, 25 fuel).
