Expand It: Travel is an awesome Cool Math Skill game featuring a lot of levels. Your main mission is to click on the smileys to make them larger so they can touch the rainbow that is above. There will be lots of deadly traps that can kill your smileys. So you have to be careful when you make them big. If one of them touches the traps, your level will be failed, and you have to restart it. Your smileys need to touch the rainbow long enough so you can complete a level.
Use the mouse to click on the smileys to make them big in the game.
