Nian Nian You Yu

5-Reel, 9-Line SlotProgressive Jackpot

Nian Nian You Yu

The aim of Nian Nian You Yu slot is to spin the reels and match symbols on the paylines. The slot also features a Progressive Jackpot game – Dragon Jackpot.

How to Play:

  • Start by choosing your Line Bet. Do this by using the +/- buttons on the coin value display on the bottom left of the screen.
  • Next, choose the number of paylines you wish to play. Do this by clicking on the Bet One button on the bottom centre of the screen. Each click adds another payline for the bet, up to a maximum of nine. Paylines can also be selected by clicking on the numbers on the sides of the reels. Please note that choosing a number in this way will also activate all paylines numerically below it. For example, choosing ‘7’ will activate paylines 1-6 as well.
  • The Total Bet is calculated by the Line Bet (coin value) x Number of Paylines.
  • When you are happy with your bets and paylines, click on the Spin button to spins the reels and play the slot. You can also spin the reels using the Bet Max button; this plays the slot at the maximum number of paylines (9) for your selected Line Bet.
  • Nian Nian You Yu slot can also be played using Auto Play. This means that you can set a predetermined number of spins to be played through automatically without your input. Click on the Auto Play menu and choose from 10, 25, 50 or 99 Auto Spins. You can stop Auto Play at any time by clicking on Stop, which replaces the Auto Play button.
  • The slot can also be played in Turbo Mode; this speeds up the animations of the reels spinning etc. leading to faster results.
  • When a winning spin has been achieved, it will be clearly highlighted on the reels and the amount won shown in the Win Field.
  • All winning combinations and their values are shown on the Paytable, which can be accessed via the Paytable button on the bottom centre of the screen. To calculate the value of a winning combination (Line Win), take the relevant figure (according to the number of Hits/matching symbols) shown on the Paytable and multiply by the Line Bet. To calculate the value of a Scatter Win, multiply the value shown on the Paytable by the Total Bet.

Paytable Page:

Clicking on the Paytable button will open up the Nian Nian You Yu Info Pages. You can move through the different pages by using the arrows on the bottom right of the screen. To return to the reels, click on the Back button. The Info Pages are as follows:

Paytable Page – shows all possible payouts for all Line Wins and Scatter Wins. The number of matching symbols that constitute a payout are called ‘Hits’. Therefore, if you land, for example, four matching symbols on a payline, the value of the win is found by looking at four Hits on the Paytable.

Dragon Jackpot – this page explains the Dragon Jackpot Game, explaining the rules and how it is awarded.


Paylines are the pathways that matching symbols must follow across the reels to achieve Line Wins. Nian Nian You Yu casino slot features paylines that work from left to right and from right to left.

Only active paylines, i.e. the ones that you place a bet on, can register Line Wins.

Please note that there is a difference between the Line Bet and the Total Bet. The Line Bet is the amount bet on an individual payline. The Total Bet is the amount on all active paylines.

About Payouts:

All possible payouts for Line Wins and Scatter Wins are displayed on the Paytable screen. To calculate the value of a Line Win, multiply the figure shown by the Line Bet. For Scatter Wins, multiply by the Total Bet.

As paylines work from left to right and from right to left, it is possible to get two winning combinations on the same payline. These are added together and paid as a total win. Please be aware that if you receive five of kind (5 matching symbols on a payline), you will be only be paid once.

If a Line Win is working from left to right, it must begin on Reel 1.

If a Line Win is working from right to left, it must begin on Reel 5.

Wild Symbol:

The Wild Symbol can substitute for all other symbols to help form winning combinations. This includes substituting for Scatter Symbols.

The Wild Symbol appears on Reels 2, 3 and 4 only.

The Wild Symbol will double the value of any winning combination that it is involved in (including Scatter Wins). However, it does not double accumulatively, i.e. you will not get paid four times the win if you have two Wild Symbols involved in a winning combination.

Scatter Symbol:

The Scatter Symbols do not need to fall on any paylines to be active, but they must work across the reels from right to left or left to right, in consecutive order i.e. one reel after another. If you land two or more Scatter Symbols anywhere on the reels in consecutive order, you will win a payout. This is calculated by taking the figure shown on the Paytable (number of Hits) and multiplying by the Total Bet.

Dragon Jackpot:

Any spin, whether it is a winning spin or not, can award the Dragon Jackpot. This is a Progressive Jackpot game that guarantees you to win one of four Progressive Jackpots.

A Progressive Jackpot is funded by taking a small percentage from each player’s wagers – in this case across all games that feature Dragon Jackpot – to build the Jackpot fund. The casino will also provide a base amount to ensure that the Jackpot(s) still remain relatively large if won twice in quick succession. This is called a seed.

The Dragon Jackpot is awarded randomly, and is independent of the main Nian Nian You Yu slot game. However, playing Nian Nian You Yu online casino slot for a higher bet will increase your chances proportionally of being awarded the Dragon Jackpot.

When the Dragon Jackpot Game has been awarded:

  • A new screen will be launched. To the left of the screen you will see the Jackpot Wheel. It has 12 segments – 4 Green, 3 Blue, 2 Red and 1 Yellow. To the right of the screen you will see the four Jackpot Awards, in ascending order of value Green, Blue, Red and Yellow.
  • You will be prompted to spin the Jackpot Wheel. Each segment that the wheel stops on will be recorded on the right of the screen. When you have landed on three segments of the same colour, you will win the corresponding Jackpot for that colour.
  • This ends the Dragon Jackpot game. Click Continue to return to the main game.

The Dragon Jackpot is awarded and funded as follows:

Seed (base amount provided by casino for jackpot) – Green = €10, Blue = €100, Red €1000, Yellow €20000.

Contribution Rate (percentage taken from each bet to fund Jackpot) – 1%.

Win Condition (result needed to win Jackpot) – Dragon Jackpot awarded randomly. You are guaranteed to win one of the four Jackpots on entering the game.

Win Requirement (how to be eligible for Jackpot) – no special requirements, simply play Nian Nian You Yu slot at William Hill Casino.

Please note the following:

  • The Dragon Jackpot awards are displayed in Euros. You will be awarded the equivalent in GBP, or other currencies (if applicable).
  • The software is designed to ensure that two players cannot win a Jackpot simultaneously.

Return to Player:

The theoretical RTP (Return to Player) for NIan Nian You Yu slot is 97.03%. This includes the 1% contributions to the Jackpot fund.

  • If you become disconnected when playing in Auto Play Mode, the next spin (but no further ones) will be completed. You can view the outcome of the completed spin by using the History tool (when you have established a connection again).
  • If you become disconnected from the internet when playing the Dragon Jackpot game, but have not yet matched three Jackpot colours from the wheel, you will be able to complete the game when you have re-established a connection.
  • If you become disconnected from the internet when playing the Dragon Jackpot game, and have already matched three colours (i.e. been awarded a Jackpot), it will be displayed on screen when you have re-established a connection and loaded the Nian Nian You Yu slot once more.
