This slot is one of the most popular games of “Amaya” and on most websites and forums you can see that rating of this slot are usually pretty good, and since the game is quite simple, it is logical to think that the reason is the vast majority of players are sufficiently satisfied with payouts in this game.
On the paytable we can see that payments for lines of 4 of a kind or lower are not really interesting, however, I have personally noticed that wild is a fairly dynamic symbol that appears very often and it is not uncommon to see three or four wilds spread across the screen during the base game.
Even so, my balance never seems to grow during the base game, but instead, my losses seem to never stop; and here I would want to admit I usually increase gradually my bet, but that is in an attempt to recover my balance.
The real opportunity for profit in this slot is during the round of free spins where most times I have obtained total winnings between 40x and 130x my total bet, this thanks to that during this round two dragon’s heads appear at every turn acting as extra wilds; these extra wilds roam randomly on all the reels and often they join to normal wilds to create some interesting hits; but the most interesting of this pair of symbols is that if both come together occupying the same position one above the other, the payout by lines you formed will be multiplied by 10x.
The problem is you will surely need to wait for a very long time for the coming of a new free round, making riskier to increase bets, and if you don’t do it, then you very likely won’t recover most of your losses.
I think “Double Happiness” is a good option only if you count with enough patience and capital to wait until the arrival of a new round of free games, otherwise, I think you rather choose any other among slots manufactured by the company “Amaya”
