Users who complete the 50 levels of the original saga map will be transported to a parallel dream-inspired set of levels.
"We're thrilled to offer new and existing Candy Crush Saga players an exciting new way of playing the game," said King's Tommy Palm.
"We hope that the new 'Dreamworld' mode will prove a fun twist for newcomers to the game and a tantalising challenge for our loyal fanbase. As with all our games, we endeavour to offer our valued players a regular flow of exciting new content - we hope that they will love the new map, as much as we've enjoyed developing it."
Candy Crush Saga was the most downloaded free-to-play game this year, Apple has confirmed.
