Double Happy is an online slot developed by Aspect Gaming. It’s a medium-volatility game with five reels, 30 fixed paylines and an RTP of 94.01%. Based on an Oriental theme, the game features Wilds, Scatters and Free Spins.
Introduction
We’ve seen a huge influx of Asian inspired slot games in recent months, including the beautiful Double Happiness slot. Double Happy sounds very similar, but in this instance, the game is based on a wedding. Hats at the ready as we prepare to spin the reels!
Graphics & Soundtrack
The wedding ceremony in Double Happy takes place on the shores of a lake backed by mountains. On the reels, you’ll find embroidered slippers, money wallets, wedding rings and the bride and groom. Graphics are workaday rather than outstanding, and there’s no soundtrack to speak of. This is fairly basic gaming, but the maths model is solid, which is the most important thing.
Double Happy RTP & Volatility
The RTP of 94.01% gives us no incentive to play the game with real money as it represents a house edge of almost 6%. This is unacceptably high for an online slots game, at least in our opinion. Combine it withmedium volatility, and there’s an instant recipe for draining a modest bankroll very quickly indeed. That means you need to be very sure of the risk element if you’re thinking of heading off to your favourite online casino to play with real cash.
How to Play Double Happy
There’s nothing complicated about the gameplay and controls of Double Happy, but if you’re not sure how it works, just follow our step-by-step guide.
1. Set a gaming budget for your session at the reels of Double Happy, even if you’re playing with virtual money. Then split your funds to give yourself at least 200 spins. We can’t guarantee you’ll come out ahead of the game overall, but any fewer spins won’t give you the best winning opportunities.
2. Adjust your stake using the Bet Per Line controls below the reels. All 30 paylines are fixed for each spin, so your stake is multiplied x30 to cover each of them.
3. Press the Spin button to play out one game.
4 Play multiple games by activating Autoplay for automatic hands-free gaming.
5. The cog button to the left of the reels takes you to the game’s rules and paytables. You can also adjust sound settings from here.
Bet Sizes & Paytable Wins
Payline costs start from just 0.01 in Double Happy. All 30 paylines are fixed in place, giving you wagering options from 0.30 to 180.00 per spin. Land three, four or five matching symbols on adjacent reels, starting from the leftmost reel, to win cash prizes paid as multiples of your payline stake, as shown below:
9 = 5x, 10x, 100x
10 = 5x, 15x, 100x
J = 10x, 15x, 100x
Q = 10x, 15x, 100x
K = 10x, 20x, 200x
A = 10x, 30x, 200x
Slipper = 15x, 35x, 300x
Red money wallet = 20x, 50x, 300x
Wedding ring = 30x, 100x, 800x
Bride = 35x, 100x, 800x
Groom = 50x, 100x, 1000x
3 x Heart Scatters = 2x total stake, increasing to 5x total stake during Free Spins.
Double Happy Bonus Features & Free Spins
The golden Wild symbol only appears on reels 2, 3, 4 and 5, so it can’t generate any wins on its own. But by acting as a substitution symbol for every icon on the paytable, it can help to complete winning lines and land you cash prizes.
Three heart Scatter symbols in any position on the reels awards a cash payout worth double the cost of your spin. But they also award the Free Spins bonus round, during which all low-value playing card symbols are completely removed from the reels. And as every dedicated slots player knows, playing with just high-value symbols can generate some incredible wins.
You start the bonus round with 10 Free Spins. If you manage to spin up three more, you’ll receive an extra 5 Free Spins, with the feature capped at 15 in total from one paid spin. Each time you land three Scatters, you’ll continue to be awarded 5x your total stake, so you’ll want to see them spinning up as regularly as possible.
If you’re already a fan of Aspect Gaming slots, the Wintrack bar needs no introduction. With every spin you pay for, a coloured ball appears on the track - yellow indicates a non-winning spin, red shows a win and blue marks the triggering of the Free Spins Bonus round. It’s quite a useful little feature, showing your progress through the game with just a glance - but remember to keep an eye on your balance, too!
Overall Review
Double Happy isn’t going to win any industry awards for innovations in game design or gameplay, but it’s still a solid game with a fun bonus round. The wedding theme is sure to strike a chord with plenty of gaming fans, so it’s a shame that Aspect Gaming decided to give the game such a woeful RTP. It’s a medium-volatility game, so it’s out of the league of penny slots fans. High rollers might be drawn in, but one look at the RTP could be enough to send them elsewhere in search of more potentially lucrative games.
We highly recommend exploring Double Happy in demo mode to see if it’s a game you’d enjoy wagering real money on. If it’s not for you, we have plenty of other game options for you to choose from, so your new favourite game is only a couple of clicks away!
