To get paid, you need to mark the symbol on the valid payline, but the number you need depends on the symbol. For some people, such as the Golden Turtle, you only need at least one, and for others, you need at least three. No matter which symbol you log in, you must read the reels from left to right.
Cai Shen plays on 5 reels and pays up to 9 paylines. These are not fixed, so if you want to reduce the number of bets, you can reduce this. You can also determine the value of the coin and set it between 0.10 and 20.00; this combined with the pay line means great flexibility in betting potential.
