What Is RTP and Why Does It Matter?

Return to Player (RTP) is the percentage of all money wagered that a casino game theoretically pays back to players over millions of spins or hands. A game with 96% RTP will return $96 for every $100 wagered, in theory, over an infinitely long session.

The key word is theoretical. In any single session, results are determined by random number generators. Short-term variance can result in large wins or losses regardless of RTP. The higher the volatility, the wider the swings.

How Wagering Requirements Affect Bonus Value

A $100 bonus with a 35x wagering requirement means you must wager $3,500 before withdrawing. At 96% RTP, your expected loss through that wagering is $140, meaning the bonus actually costs you $40 net. The calculator above shows this dynamic clearly.

BetRivers' 1x wagering requirement changes this entirely: $100 bonus with 1x = $100 total wagering, expected loss of only ~$4 at 96% RTP, making it genuinely valuable.
