Trolls Giant Lights Game

On a very cozy winter day, a giant and a troll met in the forest and started joking with each other and playing pranks on people walking through the forest. They collected stones and placed them on the path. Now everyone who follows this path must gradually clear away the stones in order to move forward.     The troll and the giant each hid behind a tree and watched the people, giggling. On your next walk in the forest, you can pay attention to whether there are stones on your path and whether you hear something giggling. Then you are exactly where the two of them are playing practical jokes.     But luckily there are the good forest spirits to help us. They have distributed power stars along the way that make people strong enough to clear the stones out of the way. Unfortunately, the troll and the giant put the stones back whenever they can.     Will we still be able to get through the forest into the light before dusk drives us home?
