In the tenth lunar month, the myriad gods gather above the clouds of Izumo,
lowering five red threads of fate for golden orbs to trace.
I. The Month When the Gods Gather
Across most of Japan the tenth lunar month is called the month without gods, for all eight million deities leave their local shrines to assemble at Izumo—where the season is known instead as Kamiari-zuki, the month when the gods are present. High upon the shrine clouds, they consult their ledgers and weave unseen ties between mortal hearts.
Beaming down from the golden clouds above the reels sits the white-bearded god of matchmaking, holding five crimson cords in his hands. Every so often in the base game he gives a sudden thread pull, turning an entire middle reel into a wild red thread that bridges the ways across the board.
II. Rungs on the Ladder of Fate
Landing enough wooden Kamiari tablets anywhere on the reels opens the Kamiari-zuki bonus round. Now the five vertical red threads running down the centres of the five reels become an amidakuji ghost-leg ladder, the classic Japanese lottery of hidden paths and unexpected meetings across the shrine.
Whenever a knot symbol lands on the outer reels during a spin, it ties a horizontal red rung reaching one step closer toward the middle thread. Every rung tied stays locked on the ladder for the remainder of the bonus, weaving an ever denser web of connections across the five cords.
III. Golden Orbs Rolling Downward
At the end of every bonus spin, five gleaming lucky orbs drop simultaneously from the tops of the five red threads. As each golden orb rolls downward, it turns sideways across every horizontal rung it encounters, zig-zagging from thread to thread on its way to the bottom of the board.
Beneath the five threads wait five wooden prize slots that slide open to reveal fresh multipliers or extra good fortune spins on every round. Wherever the five orbs come to rest at the bottom, their slots' multipliers are summed together to multiply the spin's ways win.
IV. The Great Mizuhiki Knot
Because every new rung angles inward toward the centre thread, a well-knotted ladder naturally shepherds the rolling orbs together. If all five lucky orbs zig-zag down the ladder into the exact same prize slot on a single spin, the crimson cords flare with gold and tie themselves into a ceremonial great knot.
The bride and groom dolls in the prize box bow to one another as that slot's multiplier is multiplied yet again, before the threads untie for a fresh start. It is the game's theme, not a promise: the red threads of Izumo are folklore and festivity, while every spin's outcome is still decided by the RGS random number generator.
