This slot has a structure of 5 x 3 reels and it has been provided with only 9 pay lines in which, pitifully, “Oryx Gaming” has decided not to pay also for lines made from right to left.
Another weakness of this slot is the large number of regular symbols included on it; 10 symbols are too many for a video slot of this type because the more symbols the lower it is the probability of forming lines of 3+ of a kind; it is true that wild symbol helps a little in this process, but according to my observations, this is usually not sufficient to achieve equity for the player.
In addition, prices stated on the paytable seem designed more for a slot of 25 than for one of 9 pay lines; normally and logically, slots with fewer pay lines usually have either fewer symbols or better prices.
During my playing time, I never had a big win nor a round of free games giving me more than 5 spins; my greatest hit generated a payout of $6.60 to me equivalent to about 24 times my total bet, and my second best payout was not even half of that amount and came from a full round of 5 free spins; as you can see, generosity does not seem to be one of the most outstanding qualities of this game.
Overall, “Sweet 'n Sour” is a very tight slot which basically is dedicated to squeeze your balance slowly but consistently; its design looks attractive, but money is the most important thing to consider when we are talking about any casino game, so that what I think is that this is a video slot with which we must be very careful since its math appears to be not much on our side.
