Current design target

The GDD now specifies the existing 3×3 game as a five-payline classic slot with fixed SEVENS-anywhere jackpots:

7 SEVENS:    Major  50×
8 SEVENS:    Grand 250×
9 SEVENS:    Super 1000×
Max win:     1300× including five SEVEN line wins
RTP target:  96.08% — not yet measured for our game

These are design targets derived from the public FireFruit Sevens Classic rules and supplied live help captures. They are not claims about the current backend pack.

Known blockers

  • The frozen pack implements the old 95.3967% / 65× no-jackpot game and does not match GDD 0.2.0.
  • A replacement canonical config and count-anywhere jackpot implementation are required.
  • Paytable units and jackpot additivity must be confirmed before math freeze.
  • The unique-mechanic presentation gate remains open until moving Visual Refs, backend receipts and deterministic DEV scenarios are approved.
  • Frozen v1 must remain unchanged as historical evidence.

Evidence routing

  • evidence/exact/ — exact calculation artifacts.
  • evidence/simulation/ — aggregate simulation reports and manifests.
  • evidence/parity/ — reference/runtime comparison.
  • evidence/par-sheet/ — generated PAR sheets.
  • evidence/certification/ — certification reports.
  • test-vectors/ — deterministic portable fixtures.
