Rainbet Rewards
To ensure players remain loyal and active, Rainbet has a comprehensive rewards program that adds extra value to the wagers you place on this platform.
Rewards Chest

Rakeback
Daily Bonus
Weekly Bonus
Monthly Bonus
Chest Keys
Chest Keys are the foundation of the loyalty rewards program. There are five main ranks, with some having multiple levels within the rank.
Bronze 1
Silver 1
Gold 1 - 3
Platinum 1 - 6
Diamond 1 - 5
As you progress through the loyalty program, you receive Chest Keys. These unlock various NFTs and CS:GO skins. These can be gambled with the objective being to try and win rarer skins that are worth more money.
Rewards Calendar
The Rainbet Rewards Calendar serves as a bank. When you claim Rewards Chests, the money is split between your account balance and Rewards Calendar. Once in the calendar, it is dispensed to players on a daily basis.
Rainbet Promotions
With exciting wager races, Rainbet’s promotions are open to all players - old and new. Here’s an overview of the latest offers.
$500,000 Monthly Race
Wager races are common, with several leading crypto gambling sites, including Stake Casino, Gamdom, and Shuffle, all running this type of promotion.
The rules are simple: place real money wagers, and the total amount you’ve wagered during the month relates to your position on the Rainbet Monthly Race leaderboard. The top 1,000 players with the most wager volume receive cash prizes, ranging from $50,000 (1st place) to $84 (1,000th place).
All bets placed in the Rainbet Sportsbook earn 3x leaderboard points compared to casino wagers.
$100,000 Weekly Race
The Weekly Race works exactly the same as the Monthly Race. It runs for seven days (Friday to Friday), and the top 500 racers are guaranteed a payout. The prize for the player who wins the Weekly Race is $13,000 USD. It is possible to win both the weekly and monthly races in the same period.
$25,000 Daily Race
Completing the wager race trifecta is the $25,000 Daily Race. Once again, the rules are the same. All casino wagers earn 1x leaderboard points, and sports bets get 3x. There are 200 winners each day, with the 1st-placed player collecting $4,000.
$20,000 Weekly Raffle
For every $500 wagered during the week (Saturday to Saturday), you get one ticket for $20,000 Weekly Raffle.
There is no limit on the number of tickets you can collect, so if you wagered $50,000 in a week, you would have 100 tickets in the raffle draw. The raffle is held every Saturday. 50 tickets are drawn, with each winning ticket picking up $400.
Rainbet Casino Challenges
Challenges are set by Rainbet. The casino bosses choose a game and set a target multiplier, along with a prize amount for the winner. For example, a current challenge at the time of writing is that the first player to hit a 3,000x multiplier on NLC’s Mental slot with a minimum bet of $0.50 wins $500 in cash.
