Jewel Quest: The Sapphire Dragon is a nice puzzle game in which you will take on an expedition in search for the sapphire dragon. Every level is a new match-3 game in which you need to swap adjacent gems in order to align three or more of the same type to make them disappear from the board. The goal of every level is to turn all the board to gold by making matches with the jewels on it.
The game offers three modes, which only differ in the amount of time given to complete the levels. In Relaxed mode there is no timer, in Normal mode, you have a reasonable amount of time, and in Advanced mode, you have less time. If you are a beginner, you can show popup help and move hints, which will suggest a possible move in case you are taking too much time to make a decision. Unfortunately, the game only includes one mode, and graphics are very simple and look a bit old. Sounds are simple too and the music is suitable, but repetitive.
To conclude, Jewel Quest: The Sapphire Dragon is just another match-3 game, which really doesn't have anything to distinguish it from other similar games, but you still may want to give it try.
