Domino Dice

It's a mini game-cum-exercise which helps you to improve your concentration. Just rotate the dice and keep it oriented with the falling dominos. You'll find few irregular breaks i.e. the flow of the game is not linear in order to make it more challenging. It'll eventually improve the duration of your focus as you spend more time on it. I would recommend you to spend 5-10 mins with this game 2-3 times a day to make the best of it.
