Game: Jewel Collection (Dragon or Vault) — Advantage Play Guide
Type of play
- Meter-based “must-hit-by” style overlay + combined-meter equity play.
- You’re exploiting high states of (1) the Scatter Meter toward the guaranteed Mystery Free Games at 777, and (2) the combined “extra wilds” meters that boost bonus potential.
- High variance, long-run +EV when thresholds are met; not a steady grinder.
What to look for (key meters/features)
- Scatter Meter (above reel 2)
- Increments by 1 whenever a bonus scatter symbol lands.
- Guaranteed to trigger Mystery Free Games by 777.
- Resets to 10 / 30 / 50 / 100 after it triggers.
- Weighted to hit low; it becomes increasingly likely to trigger as it climbs. Seeing 600–700+ is rare and valuable.
