How the Chained Blocks works
Chained blocks are locked in place. Clearing a set number of key blocks breaks the chains.
It is one of the core obstacles you meet through the early and mid levels, usually alongside plain colored blocks and simple gates.
How to play around it
Find the key blocks first and plan which chain to break so the freed block has an open lane.
Like every obstacle in the game, the chained blocks 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 Chained Blocks typically starts appearing around Level 65 and stays part of the rotation from that point on. Boards that feature it become more frequent as the level numbers climb.
