There are quite a few games that don't require special gadgets, but games can be dangerous if you're not dexterous enough. These include the Finger Rage game, which is available on your devices. Moreover, it is completely safe. Because you are not using your own limbs, but virtual ones. Choose a mode: for a while or a classic one and watch the red dot. It shows where the knife will hit as soon as you click on it, and the point will change its location. And if the dot is on your hand, you must react quickly and not press the knife so as not to injure it in Finger Rage.
