When the game starts, a gem will flash in the middle square. Now, it’s your turn. Click the same coloured gem at the bottom of the screen. Next, the game will flash two gems in the middle square. When it’s your turn, click the two gems, in the correct order. Each time you move to the next round, another gem will be added to the sequence. For each correct round, you’ll score one point. As the number of gems increase, so does the speed in which they are displayed. Good luck and have fun!
