Colour bombs form the letters '2' and 'K'. 2K means 2,000 which makes a reference to the level number, along with Level 1000 with "1K".
This level used to have the lowest requirement (only 2 candies) of a single candy colour (green) and was the second level with a single-digit order for a candy colour that spawns on the board. The first is 126.
This level also had the lowest requirement of any candy colour that spawns on the board.
In both versions, the candy orders are much lower than anticipated. It was anticipated that this order level requires 2,000 candies of each colour!
This level formerly had 3 colours before the redesign. This has disappointed many players, who were anticipating a very peculiar and enjoyable level.
This was one of the few levels available to mobile players that had not reached the progress in the form of events, like level 1424.
