Tap the blue "fence" above the samurai. There is no need to tap elsewhere. If you hit the shuriken exactly on the blue "fence", you will get 10 points. If you tap slightly earlier, you will still block the shuriken, but get fewer points. Look at the middle of the screen without specifically focusing on a particular point to see the shuriken falling and launching. Do not focus on one shuriken at a time. |
