Save the Earth — Defend the Forest The temperature of our planet rises every day. Forests fall. Rivers dry. Yet hope lives in the hands that reach out to protect nature. Years ago, during the great Chipko Movement, brave souls clung to the trees with their bare hands, shielding them from harm. Today, the Earth once again calls for protectors. Lumberjacks' approach to cut down the last guardians of the Earth — the trees. Your mission is clear: dig traps to block their path, plant trees to cool the Earth, and slow their advance with every tool you can find. Visit the nursery to strengthen your stand: - Plant a Large Tree and cool the Earth by 5°C. - Plant a small tree and cool it to 3°C. - Buy a Trowel to dig deeper, stronger holes. - Use Slowmo to buy precious time against the advancing lumberjacks. In the past, people protected trees through movements like Chipko. Now, you can do the same — protect the trees and save the Earth.

A relaxing marble app where countless marbles roll and tumble across the course. Watching small marbles roll one after another is soothing and fun — you may even lose track of time just gazing at them. In this app, you can enjoy many different types of courses, from classic and simple layouts to unique and playful ones. The charm lies not only in watching the flow, but also in being able to add your own twists and enjoy different ways to play. The rolling marbles can be stopped, thrown, or redirected, allowing for all kinds of surprising moments. • With stoppers, you can hold back marbles and then release them all at once. It feels exciting to see a sudden rush of marbles flowing out together. • Place pins wherever you like to scatter the flow, split the marbles into unexpected paths, or even create small dead ends. Just a little change can transform the whole course. • With the throwing feature, you can tap the screen and toss a marble right to that spot. This lets you add marbles directly into the middle of the action. • At the goal, a truck waits to collect the marbles. Once enough marbles have piled up, a start button appears and the truck drives off, only for a new one to arrive. Watching the marbles leave together with the truck is a delightful part of the experience. • Along the course, you’ll also find camera buttons. Press them to switch the viewpoint and enjoy the marbles from a fresh angle. If you change the camera right before releasing a big group of marbles, the scene becomes even more thrilling to watch. There’s a special satisfaction in building up marbles and letting them flow all at once, in experimenting with setups that create surprising movements, or in simply enjoying the unexpected. Unlike real-life marble play, where preparing many marbles can be difficult, here you can easily enjoy “lots of marbles” and “special tricks” as many times as you like. The rolling sounds and movements are soothing and calming, almost like an ASMR experience that brings a sense of relaxation. You can play however you like — relax and watch quietly, or set up bold tricks and let the marbles rush in large numbers. A marble playground you can enjoy anytime, right on your phone. Roll them again and again, and find your own favorite way to play.
