A rich red curtain hangs in the background of the Twin Happiness slot game, and the playing area sits in the centre of it.

At each side of the screen, there's a paper lantern with 243 written on it, which refers to the number of ways that winning combinations can be created.

The game logo is displayed at the top of the reel set, and underneath it, you have 5 reels and 3 rows of symbols.

Along the bottom of the screen, from left-to-right, you have the "I" button (which loads the rules and paytable), the Bet Level, Auto Play, Spin, Max Bet, and Coin Value. Both the Bet Level and Coin Value can be altered to achieve a stake size of your choice. Max Bet is the quickest way to place the highest bet allowable - £250. Auto Play lets you set the game up so that the reels spin between 10 and 1,000 times automatically.

Twin Happiness uses 12 symbols in total, including the Bar, the 7, the gold ingot, the peach, the paper lantern, the Chinese letter, and six low-value playing card symbols (A, K, Q, J, 10, and 9).

Wild Symbol:

As the Twin Happiness slot doesn't use a scatter symbol, the wild symbol can replace all of the paytable symbols. The wild is the Chinese letter, and it can land one, two, or three rows high on every reel.

Bonus Features:

The Twin Reel Feature in Twin Happiness is automatically triggered each time you click the Spin button. It picks two adjacent reels at random and links them together so that both of them display the same symbols on all three rows. Sometimes, the process ends there, but at times, the Twin Reels can expand to link up with the remaining three reels.

Obviously, the biggest wins can occur when all five reels are linked, particularly if some or all of them displayed stacked symbols.
