The game is available both online and offline – game-play is exactly the same for both, making it easier for players to switch from one to another. An unofficial Choy Sun Doa app is available on Google Play for Android devices, versions 2.2 and upwards.
Choy Sun Doa sports Aristocrat's regular five-row and five-column reels. Each reel displays three symbols and there are 25 credits to play for all reels – giving you 243 lines to play.
As is the case while playing the Five Dragons slot machine, you get the Player's Choice Free Spins Bonus round while playing the Choy Sun Doa slot too. Once the bonus feature is triggered, the machine gives you an option to choose the number of free spins and accompanying multipliers. As a rule of thumb, the higher the number of free spins you choose, the lower the potential multipliers get.
The biggest wins come with 1000 credits and the 30 times multiplier. If playing risky is your style, you can choose the other option of 30,000 credits, but with five free spins only. The highs and lows of this slot both lie in one feature – the bonus rounds.
While you can choose to play “safe” with say 15 free spin games, certain other combinations of big multipliers could bring big money to your pockets. The Choy Sun Doa projects an RTP of 95 percent in online casinos.
The gold Ingot symbol on the the Choy Sun Doa slot is the scatter symbol, which triggers the bonus feature. Choy Sun Doa – the central character is the wild symbol that replaces other symbols, other than the scatter symbol to create the winning combination. Choy appears only on the second, third and fourth reels to multiply wins during the bonus feature.
The bonus feature awards you with free games, but needs at least three gold Ingot symbols to get triggered. Symbols are matched left to right and pay all the time, not withstanding where they are placed on the reel.
If you hit three gold Ingots left to right, the slot provides you a choice of multipliers and the number of free games. When Choy appears on any of the reels two, three or four, he substitutes for other symbols to make a winning combination. This triggers the multiplier feature of the game.
The game allows you to re-trigger the free slot plays bonus round within the bonus feature. Say you managed to trigger another free spins bonus round, while playing a bonus feature; Choy Sun Doa requires you to finish the current bonus round and then offers you another choice of potential multipliers with the number of free games. Post making the choice, you play the second set of free spins triggered during the first bonus round.
The game also includes a little sub bonus feature that is pretty encouraging. Hitting the red packet on reels one and five trigger a random bonus multiplier. Your total credits increase 2x, 5x, 10x, 15x, 20x or 50x. A player playing 25 credits can thus win a maximum of 1,250 credits.
Aristocrat followed the Choy Sun Doa up with another version – the Choy Sun Returns. Graphics, art and the game-play are largely the same as the original Choy Sun except that the newer variation offers the five credit ante bet that Choy Sun Doa's predecessor the Five Dragons slot machine offers.
