Sequence Master

Can you make full use of your active memory to retrive the required information? In this game, you will first be given a grid with some numbers or letters at the start of each level. After a few seconds, the grid will be covered and you can no longer read the data on it. Your task is to click and reveal the numbers or letters as shown previously according to the required sequence indicated under the grid. Notice that this must be done within the time limit shown at the top right corner, or you will lose the game. Each correct answer gives 100 points, and the accumulated bonus for each of them is 50 points. As you reach higher levels, the grid size will increase and it will contain more numbers or letters, making it harder to be memorized. Be careful with every single click as one wrong answer leads to the end of the game!
