Situation: When auditing operator RTP settings across 15 India-facing online platforms, our team found three sites running the reduced 87.25% RTP build instead of the standard 96.21% version.

Result: By guiding users toward verified 96.21% RTP builds, we helped players avoid an unnecessary ~9% increase in long-term theoretical house edge.
Methodology note: this audit reflects our internal review workflow, meaning manual inspection of the in-game info panel in real-money mode plus network-level verification of the game host. It is not a peer-reviewed sample. Readers should repeat the same two checks on their own account rather than rely on any third-party claim, including ours.

These numbers come from a crowd-sourced tracker, not a peer-reviewed dataset. Methodology and sample composition are not fully published, so treat them as directional indicators rather than certified probabilities.
Independent public-health evidence explains why the format deserves caution regardless of the exact hit rate:
