How Niuniu Mahjong works basically
This is a traditional slot game, combining modern gameplay with images inspired by the Chinese folk game Mahjong. Although it belongs to the slot game genre, the way the game operates is quite new and special, especially for those who experience it for the first time.
When starting the game, players will be taken to a virtual Mahjong table with a layout of 5 columns and 4 rows. On the table are Mahjong cards that act as spinning symbols. The player’s task is to spin these symbols to form a combination of 3 or more identical symbols according to fixed paylines. In particular, when entering the bonus round (Free Games), the table layout will expand to 6 columns, increasing the chance of winning.
It uses 40 fixed paylines that all lines are activated in each turn; players do not need to manually select the number of lines as in some other slot games. A winning combination is determined when at least three identical symbols appear consecutively from left to right on one of the specified lines.

Special features in Niuniu Mahjong
The game has many special features that contribute to enhancing the experience and increasing the player’s chances of winning. Specifically, the highlights of the features that you should not miss when experiencing this game are
Wild Symbol
In Niuniu Mahjong, the Wild symbol is represented by a yellow card. This is a symbol that can replace all other regular symbols, helping players easily complete winning combinations.
However, the interesting thing is not only in the substitution function. When entering the free spins, the wilds that appear will turn into Sticky Wilds, which means that their position on the game board is fixed until the bonus round ends. Thanks to that, each spin in the bonus round after that has the ability to create a higher winning combination, even consecutive wins on multiple lines.
Free Games
One of the most attractive features of the game is the free spins round, which is activated when players collect 3 or more Scatter symbols. The Scatter in the game is a red die with the letter “F” on it, which can appear anywhere on the 5 columns of the game board.
As soon as the Scatter appears enough, the dice will “roll” and display the number of dots from 1 to 5, depending on the dice face. The total number of dots on the dice is the number of free spins the player receives. For example, if you roll 4, 2 and 5, you will receive 11 free spins.
In particular, in this bonus round a 6th column is added, expanding the game board to 6 columns and 4 rows. Sticky Wilds start to take effect from the first turn if they appear.
In addition, some dice may have the symbol +1; if they appear in the bonus round, they will add 1 free spin to the current total.
This feature offers great winning potential and is an indispensable highlight when talking about the uniqueness of the game.
Wild Forecast
The Wild Forecast feature is an interesting and quite surprising random element in Niuniu Mahjong. Before the cards fall on the table, the system can randomly select a column to forecast. This column will be highlighted for players to easily recognize.
If during that spin, a Wild symbol falls on the marked column, the entire column will turn Wild, helping to create many consecutive winning combinations in the same spin. This is an opportunity to increase the reward right in the base game, without having to wait for the free spins.
This feature does not occur often, but when it does, it can bring unexpected and high-value rewards.
Sticky Wilds
While the Sticky Wild feature is often combined in the Free Spins round of many other slots, in Niuniu Mahjong, its presentation is very vivid. Mahjong characters will interact directly with the game board, with the action of “slapping hands” to make the Wilds stick to the table, creating a lively role-playing feeling and increasing excitement for players.
Accumulating many Sticky Wilds at the same time during the free spins will significantly increase the ability to create a winning streak and achieve high rewards, especially if they fall on the central columns.

Column expansion
Another special feature in the reward mechanism of Niuniu Mahjong is the expansion of the game board. As soon as the player enters the Free Games round, a 6th column will be added to the right of the game board.
Although the number of paylines remains the same at 40, the addition of an additional column means
- More symbols are displayed, making it easier to create winning streaks.
- More Wilds and Scatters can appear in the same turn.
- Combined with Sticky Wilds, the 6-column table creates combinations with significantly higher rewards than the base game.
Conclusion
It can be seen that Niuniu Mahjong is a type of slot game with depth and big prizes for participating members. This is the ideal choice for slot enthusiasts. Join now at BET24 to try your hand at this hot game in 2025.
