NetEnt appear to have taken two of the most popular online slot game themes and have mixed them together to create their Twin Happiness slot game.

Using a predominantly Asian-styled theme in regards to the background of the game, our Twin Happiness slot review found that the game used a number of icons that would be found on a classic fruit machine that would be found in Las Vegas.

Indeed, combining two great and hugely popular themes will have been a solid move by NetEnt and one that has proved to be a brilliant move by the developer.


Players will find that Twin Happiness is played across five reels and features a 243 Ways to Win payline mechanism. This means there are a number of wins that players can form, thus providing them with the potential to earn some huge rewards when making the best winning combinations.

Bets can be placed from as little as €0.25 per spin, whilst those looking to earn the rewards from this Asian-themed game can place bets as high as €125 per spin. Bettors are also able to take on the reels from any device they choose, as the slot game has been made available for mobile play as well.

As is traditional for many of NetEnt’s titles, there is a game panel across the bottom of the grid which allows players to customise their gameplay experiences. The first button that may be noticed is the ‘Max Bet’ option, which will allow those who want to bet with the most possible on each turn to be able to do so with a click of a button. The next button is the ‘Autospin’ button, which allows for the reels to be spun uninterrupted for a set period of time.

As mentioned, the icons on the game represent some of the more traditional symbols to be found on machines, although some of them do also match the Asian theme being followed – all of which can be experienced in the Twin Happiness Free Play version on our page.

The playing card values – 10, J, Q, K, and A – provide players with the lowest rewards when formed in a winning combination, whilst the peaches, the lanterns, the bars, the lucky pink 7s and the ingots will reward bettors with greater values. The ingots provide the biggest prizes as these can reward either 2x, 10x, or 40x the bet when 3, 4, or 5 appear on a payline.

The Twin Happiness slot game also features a Wild symbol that has the ability to substitute all symbols, however it does not appear on reel one.

Feature Bonuses

One of the Twin Happiness bonus features available in this NetEnt slot game, is a rather appealing one!

This feature is known as the ‘Twin Reel’ feature and this can be triggered randomly throughout the game. Each spin will begin with identical, adjacent twin reels that will link together to show the same icon. This feature will then randomly make the reels expand to provide players with either three, four or five reels that show the same symbols!

If players are able to trigger this feature with an ingot, then they could pocket a win of up to 1,080x their bet!

RTP (return to player)

Twin Happiness slot game comes with a return to player (RTP) rate of 96.45% and has a medium volatility level, thus players can expect to receive a number of rewards when they spin the reels for a significant period of time.
