Duel leans hard on one claim: zero house edge, 100% RTP, on its in-house Originals. It is a bold line, so it is worth unpacking what it means and where the realism sits.
What 100% RTP means
Return to player (RTP) is the share of wagers a game pays back over the very long run. A standard slot might run 96%, keeping 4% for the house. A game at 100% RTP is, in theory, break-even across infinite play: no built-in edge against you.
What it does not mean
It does not mean you cannot lose. Variance is real, and over any single session you can run well below or above the long-run figure. 100% RTP removes the structural edge; it does not remove risk, and it is not a strategy. Treat it as a fairer starting point, not a guarantee.
Why rakeback still matters
On higher-edge games, your rakeback rate gives back a share of that edge. On a true zero-edge Original there is little edge to share, but you are also not fighting a margin in the first place. The two features work toward the same goal from different directions: keeping more of your money in play.
Zero house edge is a genuinely player-friendly design. It is not a licence to bet beyond your means, and no RTP figure changes the one rule that always applies: only play with money you can afford to lose.
