Type of play
- Progressive-meter scouting + selective play (must-hit style free-games meters). Mostly a “play only when built up” game; otherwise skip.
What to look for
- Two separate free-games meters: Green and Purple.
- Each meter starts at 6 free games and caps at 20.
- Your key number is the combined total of both meters.
When to play (floor rule)
- Play only when: (Green free games + Purple free games) ≥ 32.
- This is roughly break-even to a small winner; higher is better, but the cap at 20 limits the upside.
