The object of Jewel Shuffle is to score as many points as possible by swapping the positions of the jewels so that at least three of the same jewels are next to each other, either vertically or horizontally. You can only move a gem one at a time (i.e. swap places with an immediately adjacent gem). To do this, you can drag the gem in the direction you want it to move. If you don't want to drag, you can also click or tap the gem you want to move, then click or tap the gem you want to swap with. If they match identical gems, they will make them disappear and new gems will fall on the board. Combine multiple matches in one move to rack up a ton of points! Create longer matches to score extra points and unlock powerful bonus gems. As you earn points, the bar at the top fills up. Each time this happens, you advance to the next level, and the score multiplier on the left will increase. Just make sure you don't run out of moves during the process!
