RichGame Electronic Ninja Slot: 51000x Jackpot Goes Viral, Players Rush!

"Nin Kunoichi" is an online slot game developed by Fuyoo Electronics, themed around Japanese ninjas. Unlike traditional slot machines, this game has no paylines and instead features a full-reel multiplier and cascade mechanism. You can bet freely, and collecting 8+ to 12+ matching symbols will award multiplier-based prizes, with a maximum payout of up to 51,000x!

This ninja-themed slot game features simple and intuitive rules. Its two main highlights are: 1) "Buy Feature" — meaning you can trigger bonus games without spinning the base game; and 2) "Multiplier Symbols" — when they appear, you can receive multipliers ranging from 2x to 500x, and these multipliers can stack. The minimum bet is just 1 unit, with a maximum of 2500 units, making the game highly dynamic and engaging.

Nin Slot Game Rules

Multiplier Symbol

When a multiplier symbol appears on the reels, it grants a random multiplier between 2x and 500x.
Once there are no more cascades, all multiplier symbols on the board are summed up. Total Win = Reel Win x Sum of Multipliers.

Oni Mask (Scatter Symbol)

Landing 4, 5, or 6 masks awards 150, 250, or 5000 credits and triggers 15 Free Spins.
During the Free Spins, landing 3, 4, 5, or 6 more will award 5 additional spins, up to 100 total.
In Free Spins, whenever a multiplier symbol appears along with a win, the multiplier is added to a cumulative total multiplier.
When a multiplier symbol adds to the total and a win occurs, Total Win = Reel Win x Accumulated Multiplier.

Nin Slot – Buying Free Spins

Bonus features can be activated via the Buy Feature.
Buying costs 100x your current bet and instantly triggers the Free Spins feature. (e.g., Bet 1 unit → Buy for 100 units)
A minimum of 14 bonus rounds can be played.
The bet amount within Free Spins matches the amount used to purchase it.
