Rain is a chat feature that sends some coins to multiple participants in a chat room at a time. And to cheer your presence in our chat we have a so-called Rainbot named DuckyCloud.
Our Rainbot sends $1 value of a coin that has been set as a "lucky coin" that week to each of 10 active players in the EN and RU chat, and $0.5 in any other chat every ~3 hours.
In order to receive rain, you need to send at least one message to the chat and be an active player. Parameters such as sent rains, sent tips, amount of messages, no clones, recent deposits, and the recent wager amount will make you a high priority member for the rainbot.
