Round 1: Both at 97% RTP - so what actually separates them
Both games run identical 97% RTP with a 3% fixed house edge. The distinction is whether the distribution is a single fixed shape or a player-adjustable one.
Aviator ships a single crash distribution pinned to 97% RTP. The probability of reaching multiplier m is about 0.97 divided by m, so 2x lands on ~48% of rounds, 5x on ~19%, and 10x on ~10%.
About 3% of rounds end instantly at 1.00x, which is the 3% house edge expressed directly inside the distribution. No knobs, no sliders, no variance tuning. Every player sees the same shape.
The simplicity is a feature: you never have to think about a configuration step before placing a bet. The shipped 97% is the number operators can ship at 94-96% variants depending on jurisdiction, which is the one variable worth checking inside the info panel at your specific casino before a real-money session.
Aviatrix matches the 97% RTP exactly. What it adds is a Variable Volatility slider that reshapes the crash distribution without changing expected value. Slide left and the distribution tightens around the 1.5x-3x range, lifting the 1.5x hit rate from ~65% toward ~72% while making 10x+ hits rarer. Slide right and the distribution stretches, boosting 10x+ frequency toward ~14% but raising insta-crashes under 2x along with it.
Critically, the RTP stays at 97% at every slider position. The slider is variance customization, not an edge tweak. Expected loss per dollar is identical to Aviator. The real value is for players who already know their preferred cashout target range and want to dial in a distribution shape that matches, rather than hunting for a target that approximates it.
