How the Magnet Block works
When two blocks of the same color line up with it, the magnet snaps them together.
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
Line the pair up deliberately, because the snap changes the shape you have to route.
Like every obstacle in the game, the magnet block 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 Magnet Block typically starts appearing around Level 1750 and stays part of the rotation from that point on. Boards that feature it become more frequent as the level numbers climb.
See it in action on the Levels 1726–1750 walkthrough index, or browse every mechanic on the mechanics guide.
