Challenges

Challenges are arcade levels but with a twist: you must complete them before the timer runs out which is indicated by a red bar at the bottom of the screen. Some extra time will be recharged upon completing a level, which would get shorter and shorter in each different challenge. You will gain a ball when you complete a challenge for the first time (Green ball when you finish Level 1-10 challenge etc.). Unlike in the Arcade pack or the Community Packs, by watching advertisements, you can recharge a tiny amount of time.

There are 15 challenges in total, including:
 * Level 1-10
 * Level 11-20
 * Level 21-30
 * Level 31-40
 * Level 41-50
 * Level 51-60
 * Level 61-70
 * Level 71-80
 * Level 81-90
 * Level 91-100
 * Level 101-110
 * Level 111-120
 * Level 121-130
 * Level 131-140
 * Level 141-150

Trivia
