No particular difficulty on this one, except the liquorice locks, but with 5 colours, it's easy to break through them.
Once you get rid of the liquorice locks, you can literally get millions of points because there are five colours that result in many cascades, which generate many +5 candies. However, doing this is a very hard task, but it is possible on mobile.
Shuffles may occur at the start, taking up some time.
The player is required to earn at least 850 points per second (50,000 points / 60 seconds = 833.33 points per second). Note: This is the theoretical minimum. In practice, +5 second candies can be collected, decreasing the amount of points need to be earned per second as the amount of time available is increased.
