Activating the Rakeback reward, you will receive back a percentage of your "theoretical losses" to Blaze.
The "theoretical losses" are calculated through this formula:
"theoretical losses" = (1-RTP) * wagered amount.
Where RTP (Return to Player) is a value expressed as a percentage that represents how much money a player can expect to win from their bets in a game. For example, if you play a game with an RTP of 95%, then for every $1 you bet you are theoretically expected to earn $0.95 back, and the "theoretical losses" would be $0.05.
Now you apply the Rakeback % to the "theoretical losses" to get the amount you will receive through the Rakeback reward.
The Rakeback reward amount is calculated as follows:
(1 - RTP) * Wagered Amount * Rakeback Percentage
You've received a Rakeback reward that gives a 20% Rakeback which lasts for 1 hour. The RTP of the game you have played is 93.33% (Crash) and you have wagered a total of 10000 in your currency.
The formula would be (1 - 0.933) * 10000 * 0.20 = $134
Your Rakeback in the above example would be $134.
