* Look ahead at the right side to determine which type of wave is approaching.
You can then decide to move up or down as required. The sooner you know
which way to move, the better.
* When you miss a wave, you will get an option to watch a video ad to continue.
Do this when you can beat a previous high score or during a very long run.
The number of videos you can watch per day is limited, so save them for when
they are needed themost.
* You can earn a new character by liking the game on Facebook.
* Save your stars for characters that cost 200 or more. The characters available
at 75 and 150 can be earned without spending stars. If possible, make the 700
stars character the first one that you purchase.
Stars are spent on new characters. However, you can usually ignore the stars
while progressing. They will often lead to ending the game. Instead, just
collect them naturally. Focus on upcoming waves and get to the same level as
they are as soon as possible.
