This level is currently nearly impossible to beat without boosters (or even with boosters). This is likely caused by a level buff, lack of moves, an objective which requires insane luck to fulfill, a level glitch, or a design error. This level is currently, or likely one of the hardest levels of the game.
Level 4790 is the fifteenth and last level in Cosmic Canyon and the 1240th candy order level. To pass this level, you must collect 2 colour bombs and 22 frosting layers in 21 moves or fewer.
