RTP & House Edge Explained
Return to Player (RTP) is a percentage figure that describes the theoretical long-term return a game pays back to players relative to the total amount wagered. For example, a slot machine with a 96% RTP will — over a statistically significant number of spins — return ৳96 for every ৳100 wagered. It is a mathematical average calculated across millions of game rounds, not a guarantee of what any single player will receive in a session.
House edge is simply the inverse of RTP. A game with 96% RTP carries a 4% house edge — meaning the casino retains, on average, ৳4 out of every ৳100 bet over the long run. Understanding house edge helps players make informed decisions about which game types suit their playing style and budget.
Different game categories carry very different RTP ranges. Skill-influenced games like blackjack and video poker tend to sit at the higher end (97–99.5%), while themed video slots can vary widely (92–98%) depending on the provider and title. Live dealer games such as baccarat and roulette typically sit in the 94–97% range. Always check the game's information panel for its specific published RTP before you start playing.
At 678b, all game RTPs are sourced directly from certified providers such as Pragmatic Play, Evolution Gaming, NetEnt and Microgaming, whose titles are tested by independent third-party auditors. We strongly encourage every player to treat RTP as an educational tool for budgeting and game selection rather than a prediction of personal outcomes.
