Neon Nexus play-money mathematics

Play-money prototype. Not certified for real-money gambling. The legacy platform identifier remains orbit-breaker; it is not player-visible.

Model​

  • Base: 5 reels × 4 rows, 20 fixed paylines
  • Nexus Paths: 5 reels × 5 rows, adjacent-row connected paths
  • Ordered reel strips with unbiased stop selection
  • Four scatters trigger three feature spins at ×1, ×2, ×3
  • Wild substitution; feature exposure capped at 10,000× bet
  • Configuration: services/orbit-games/math-config/math-config.json

The provider service determines and persists the complete outcome before the client animates. Speed and quick-stop affect presentation only.

Development builds expose three server-authoritative prototype payout profiles: conservative (~92%), reference (~96.06%), and promotional (~98%). They scale payout multipliers without changing reel stops, hit selection, feature frequency, or presentation timing. Production ignores client-selected profiles unless ALLOW_DEMO_RTP_PROFILES=true is explicitly configured. Each non-reference outcome includes its profile and target in model_version.

Prototype evidence​

SPINS=1000000 SEED=42 npm run simulate:rtp reported approximately 96.09% total RTP, 94.04% base RTP, 2.05% feature contribution, 31.8% hit frequency, one feature per ~433 rounds, and 327.1× maximum observed win.

These are prototype simulation figures, not certification claims.

Run a selectable profile with:

RTP_PROFILE=conservative SPINS=1000000 SEED=42 npm run simulate:rtp
RTP_PROFILE=standard SPINS=1000000 SEED=42 npm run simulate:rtp
RTP_PROFILE=promotional SPINS=1000000 SEED=42 npm run simulate:rtp
