How this world plays
The six-reel, four-row field pays matching symbols across at least three consecutive reels from the left. Each matching position contributes a way; a gap ends the combination. Wild substitutes for ordinary symbols. Multipliers apply only to their recorded positions. All-Wild ways use the highest ordinary symbol once.
Rainbow Cascade
Successive cascades add colours and increase a multiplier.
Free rounds and the bonus chamber
Three or more free-round emblems start eight free rounds. A later trigger adds four, up to 24 automatic free rounds per paid cycle. Six play-token medallions open Hold & Spin: existing medallions stay locked, a new arrival resets the counter to three, and at most 12 re-spins are played. Values are fictional credits. The final pot is counted once.
If a free-round trigger has no Hold & Spin chamber, choose three of nine sealed vessels or use Guided play. You may Collect the current pot early. Hold & Spin offers Collect or an optional fair Double: a loss removes only the unresolved bonus pot; already awarded base credits stay yours. Up to four attempts are allowed. A 24-tile reveal shows 13 successful marks or 11 on a loss. The whole cycle remains subject to its award cap.
Your Seven-colour prism collection
Each collected Luminous seven-colour fragment is saved separately for this game and play level. Every six fragments unlock the next chapter, up to six. An unlock affects the following paid round. Chapters add a single Wild, two Wilds, a Wild column, four Wild positions, a 2 × 2 Wild area and a 2 × 3 Wild area when the chapter feature triggers.
- Dew Prism
- Scarlet Stream
- Amber Rainbow
- Jade Falls
- Azure Arc

Play levels and awards
Choose 50, 100, 250, 500 or 1,000 fictional Play Credits per paid round. Automatic free rounds and re-spins have no additional cost.

Controls and interrupted connections
Space starts one round when controls are ready. Quick shortens reel travel; Finish resolves the current animation only. Replay replays the last saved round without another charge. Autoplay is limited to 5, 10 or 25 rounds and stops when the tab is hidden, a choice needs attention, a reminder appears or a request fails. Reloading restores saved results and unresolved choices. Sound starts off and needs your gesture to enable it.
Preview automatically plays clearly labelled recorded examples. Its choices are illustrative and never change a wallet. Player Care provides session reminders and account breaks.
