Twin Happiness is a NetEnt mobile slot that features Chinese-themed symbols and music. While you could easily write it off as just another oriental slot due to its name, the Twin Happiness slot offers you a whole lot more than other games that use similar themes.

For example, you get 243 ways to win instead of fixed paylines, and there's over 1,000 times your stake to play for. In addition, there's the Twin Reels feature where (like in NetEnt's Twin Spin), reels are linked together at the start of each spin, and if you're lucky, you could end up with all five reels displayed the same symbols.

The RTP (Theoretical Return to Player) of Twin Happiness is 96.55%, and it costs between 25p and £125 to play on mobile devices.

Our Verdict:

With Twin Happiness, the Linked Reels Feature makes taking every spin an exciting prospect. And, as there are also wild symbols, it's even easier to form winning combinations.

The 243 ways to win pay structure has become a popular format for many software developers, and the Twin Happiness slot gives you 243 ways to win for as little as 25p per spin.


To play the Twin Happiness slot game on your mobile device, you'll need to turn your tablet or smartphone sideways. This gives you a full view of the 5x3 playing area, as well as the Chinese-themed background. Turn your device's volume up, and you'll be treated to a calming oriental soundtrack.

The graphics are sharp and designed in intricate detail and the gold symbols, in particular, shine brightly against the dark red background.

The 243 ways to win pay system is described in more detail in the rules (which you can access through the menu). Winning combinations can be created with at least three matching symbols such as the gold ingot, the paper lantern, the Chinese writing, the peaches, the Bar, the 7, and the six playing card symbols (A, K, Q, J, 10, and 9).

The Twin Happiness slot game uses the NetEnt Touch platform, which gives you mobile-optimised menus and buttons that are discreetly tucked away to the side of the reels. The menu includes several settings such as the Bet Level and Coin Value, AutoPlay, the paytable and rules, and the graphics and sound settings.

Wild Symbol:

The Chinese writing is the wild symbol in Twin Happiness, and it can appear on Reels 2, 3, 4, and 5 as a single, two-rows-high, or three-rows-high symbol. As there's no scatter symbol, the wild can substitute for all others to help make winning combinations.

Bonus Features:

We've seen the Twin Reel mechanic used before in NetEnt's Twin Spin slot, and it's great to see it featured in the Twin Happiness slot too.

As well as having 243 ways to win on every spin, the game automatically links two reels together at the start of each spin. This means that the symbols on both reels are the same. You can often get stacked symbols on the linked reels as well, which make it more likely that if a win is created, it will be worth more. Sometimes, the feature can allow the linked reels to expand and create a longer link that takes in three, four, or even all five reels.
