A recent change was made to this level to make it arguably harder, causing the information to undergo a major change. A new difficulty is yet to be or has just been decided.
Level 2778 is the thirteenth level in Rainbow Rapids and the 407th mixed mode level (267th jelly-ingredients). To pass this level, you must clear 14 single and 30 double jelly squares and collect 2 cherries in 13 moves or fewer.
