Joe Danger Touch Hints for iPhone/iPad
Try experimenting with the different costumes if you are struggling to complete a challenge as each outfit has it's own stat boosts.
Always try and complete the course objectives to get medals as you will need to have earned a certain number to unlock later stages.
To score extra points as you progress through the game just do tricks whenever you do a big jump and wheelies along flat ground.
When you reach the bonus stage the game will force you to play as a certain character. If you try the character and restart these levels the character will change and you will be locked out until you can afford a new skin.
