How the Colorful Crate works
The crate disappears once every block of its color has left the board.
It belongs to the later generation of obstacles: the boards that use it assume you already handle arrows, ice and ropes without thinking, and stack a second rule on top.
How to play around it
Finish that color completely before spending moves on anything else.
Like every obstacle in the game, the colorful crate never makes a level impossible. Every board can be finished without boosters, so if a route feels blocked, the answer is usually the order in which you clear the other colors, not the obstacle itself.
Where you meet it
The Colorful Crate typically starts appearing around Level 920 and stays part of the rotation from that point on. Boards that feature it become more frequent as the level numbers climb.
