Each spin starts with identical, adjoining twin reels that are linked together and can appear adjacently on any of the reels. During the spin, twin reels can expand to triplet, quadruplet, or even quintuplet reels. As the reels begin to spin, so does the excitement for the player – will the spin be a twin, triplet, quadruplet, or a quintuplet spin?

Wild symbols appear on reels 2, 3, 4, and 5, substituting for all other symbols.

Twin Happiness™ offers 243 ways to win with no bet lines. A winning combination occurs when matching symbols appear in any position across three or more adjacent reels, starting from the leftmost reel to the right.
