If you want to test your attentiveness then play the new online game Cup Chase. In it you will play regular thimbles. In front of you on the screen you will see a playing field on which there will be three cups. Under one of them you will see a black ball. At the signal, the cups will begin to move chaotically across the playing field until they stop. You will have to click on one of the cups. If there is a black ball under it, then you will be counted as the correct answer and will be awarded points for this in the Cup Chase game.
