The way to the finish line is full of shortcuts and traps. You'll find Ladders, that will help you move faster, but also you'll run into Slides that will make you move back.
The first time you land on a box with a slide, you can get around it by viewing an ad or by paying a few coins. The next time this happens, you can avoid the fall only by paying coins, if you have them available.
Remember that you can also use the Shield PowerUp to avoid falling down a slide.
Don't be discouraged; if you fall down a slide, you will not lose your turn.
Cheer up! If you fall down a Slide, you won't lose your turn.
