How do you score 12000 points without collecting coins?

You buy a boost for 1000 feet in the store and before you get to the coins press it.

You don't, you have to buy that mission

I used the headstart to pass this mission

You can use the super head start to fly without gitting any coins

It's very simple. Try not to get coins! Go to the lines that has no coins in them, if not possible, use a hover board and lose the game by doing it all the three lines will be clean. If there is no bus or barriers to help you losing the game try pushing against lane 0 or 4 two times. It might be a little tricky but push through line 4 then come back to lane 2 and again line 4. IT IS POSSIBLE

You use head starts and then when they run out die and you save yourself with keys and over and over

It is very simple. If it is a mission, you buy it. You can do this by going to the store. If you are trying to complete Coin Cautious, you have to buy three headstarts. You do this by going to the store as well. Use all three at the same time. At the end try not to get the magnet. If this doesn't do it, avoid getting coins. If this is not possible, double tap for hoverboard and wreck it into train, barrier, wall, ect. Before getting amy coins. If this is not possible, bump into either side twice and that will knock away coins for a while. This method worked for me, did it for you? Comment any questions and I'll try to anwer them.

Make sure you have a coin and two headstarts use on head start when it's over bump on it a train use a key and the use another head start
