Si Xiang Slot Review

The Si Xiang slot game can be found at casinos offering Iron Dog software. Iron Dog are one of the smaller software providers currently on the market, but the appear to be a subsidiary of the far larger and better established 1x2Gaming. They do not offer a full casino platform, but primarily seem to be used as a bolt on package for extra slots games. Iron Dog do publish the Return to Player (RTP)/House Edge information for their slots games within the game paytable. As such we know that the house edge for Si Xiang is 4%.

Si Xiang consists of 5 reels, 4 symbols high with 28 possible paylines, playing from left to right.

Special Symbols:

Magic Portal – One of the most useful symbols in the game is the “Magic Portal”. You’ll recognise it as a gold dragon circling a whirl of purple light. The symbol acts as a multiplier, with 3 “Magic Portals” multiplying the win by 75, 4 multiply it by 250 and 5 multiply it by 888. It also helps to trigger the game’s free spin feature.

Wild – The blue and yellow “Ying Yang” is the wild symbol. Wilds can appear at random on the middle reel, sent over from the left-hand side of the reels to replace a pre-existing symbol. Wilds substitute for all other symbols and will multiply any win they contribute to by 3. If the Wild symbol replaces a “Magic Portal” then you will trigger the game’s free spin feature.

Bonus Features:

Free Spins – You can win up to 100 free spins when the free spin feature is triggered. When this happens you will randomly unlock one of the four expanding wilds described here:

Azure Dragon – The “Azure Dragon” expands vertically and fills 3 symbols worth on the reels, acting as a wild for the duration of the free spins. With each spin the “Azure Dragon” will move randomly to the left or to the right and more than one “Azure Dragon” can appear on the reels.

White Tiger – The “White Tiger” expands horizontally and fills 3 symbols worth on the reels, acting as a wild for the duration of the free spins. With each spin the “White Tiger” will move randomly up or down and more than one “White Tiger” can appear on the reels.

Black Tortoise – The “Black Tortoise” expands to fill 4 spaces on the reels in a 2×2 formation, acting as a wild for the duration of the free spins. With each spin the “Black Tortoise” will move randomly in any direction. There can be more than one “Black Tortoise” on the reels at any time, but once they have moved off the reels the free spins will end.

Vermillion Bird – The “Vermillion Bird” expands to form vertical and horizontal lines of three symbols that interest in the middle, creating a cross and filling 5 spaces on the reels. The symbols will act as wild and the free spins will end when the “Vermillion Bird” moves off the reels. More than one “Vermillion Bird” can appear on the reels during the free spins feature.


Si Xiang is a take on a theme that those of you familiar with other slots games might have seen before. The idea appears to come from Chinese astrology, with the 4 expanding wild symbols used in the free spins feature being the 4 most prominent within the culture. It is a theme that is rich and should be easy to turn into fantastic looking slots game with immersive bonus features. Unfortunately, Iron Dog just haven’t done enough with the material on display. The expanding wilds in the free spins are a nice touch but with no bonus features, no animated sequences and no real narrative to drive the game forward Si Xiang is unlikely to hold your attention for long. The game looks OK, the background is intricate and detailed but the symbols lack the sheen that other software designers use in their games. The house edge is slightly above average but in keeping with current Iron Dog output and certainly wouldn’t be the sole contributor to the average rating we’ve given this game.
