One of the best brand-new online idle games for kids we offer is called Idle Zoo Safari Rescue. When you initially enter the zoo, it is empty. Purchase an elephant, then click it to receive cash for each tap. The elephant's level can be upgraded if you have enough coins, say ten, so that each time you click, you will receive more coins. By selling your first animal, you can expand the zoo and increase its revenue potential by purchasing more animals. Always tap, then invest your money in new animals and enhancements.
