The Apology Day/Weekend is a spontaneous event set up as compensation for a rollback. During the event, IAP (In-App Purchases) will give 25% more gems, and all players have a chance of receiving a lucky drop when breaking blocks. These lucky drops are indicated by a small red flash, and they give the item itself, it's seeds, and a gem drop of a higher value than what one would usually get from the block. This bonus only applies to blocks which normally drop gems and seeds. It also gives Lucky! Mod to all players until the end of the day.
