Values are multipliers of the line bet. Wins pay left→right from reel 1 on adjacent reels. Scatter pays on the total bet from anywhere.
ANCIENT DRAGON (Wild) — appears on all five reels, most often on 2, 3 and 4. Substitutes for every symbol except the Rift Portal, and pays in its own right on a full line.
RIFT PORTAL (Scatter) — 3 / 4 / 5 anywhere awards 15 / 20 / 25 Free Games plus a scatter pay of 4× / 20× / 100× total bet.
EXTENDED LINES — the raid opens with 3 sealed bonus paylines (31, 32, 33) that exist only inside Free Games. Every free spin has a 60% chance to break one seal. They cost nothing extra — once live, an extended line pays exactly like a base line for the rest of the raid, so a raid that opens all three is running 33 lines on a 30-line bet.
RAID XP — during Free Games every spin grants XP (bonus XP for a winning spin). Each LEVEL UP raises the raid multiplier: ×1 → ×2 → ×3 → … up to ×10, applied to every win for the rest of the feature.
WAVE CLEARED — 3+ Portals during Free Games retriggers +8 spins.
Runs the real game engine headlessly — same reels, same paytable, same free-game logic — and reports measured return to player. 1,000,000 spins takes a few seconds.
