In video games, there are different levels that you have to complete. Imagine you are climbing up a big tree and each level is like a branch on the tree. Once you successfully complete a level, you climb up to the next branch and the game becomes a little harder.
Each level has different challenges, like collecting coins or defeating enemies. These challenges are like puzzles, and you have to use your brain to figure out how to solve them. As you complete more levels, you get better at the game and can solve the puzzles more easily.
Sometimes, there are certain requirements you need to meet before you can move on to the next level. For example, you might need to collect a certain number of coins or defeat a big boss. Once you have completed all the levels, you have beaten the game!
