Game rules, controls & symbols
5 reels, 3 rows and 20 fixed lines. Match at least three symbols from the left. A hidden platform opens an additional bonus reel. All amounts are fictional Play Credits.
Wild substitutes for ordinary symbols. Recorded multipliers apply to matching symbols in that frame. Feature reveals belong to the same round and do not require another credit amount. The displayed total includes every confirmed frame, subject to the maximum round award.
Fixed lines start on the leftmost reel and need at least three adjacent matches. Only actual matching lines are highlighted.
Space starts a round when controls are ready. Quick spin shortens presentation. Autoplay is limited to five or ten rounds and stops on an error, hidden tab, reminder or pending choice. Replay repeats the last presentation without using credits.
Base award multiples
Values below multiply the selected total credit amount for each resolved line or way. Values are rounded for display; the server applies whole-credit rounding and the round cap.
