Rules & symbol guide

All outcomes use fictional credits. No purchases, transfers, redemption or prizes of value. A Preview changes no credits.

Twenty fixed paylines run from left to right; at least three matching symbols are required. Wilds substitute for ordinary symbols. The final field, highlights and award are recorded together.

Four-symbol matches multiply the three-symbol award by1.5; five multiply by2.
