You can see the field.
Iron filings trace the pull of every pole and shift as the pieces slide. Field hints mark the lanes your magnet reaches, so you can read a move before you make it.
One move, a whole chain.
Blocks carry red north and blue south faces. Line up opposites and a block snaps onto your magnet, then starts pulling too. A single step can reel in a string of blocks. Line up matches and they push away.
Build the shape.
Fill the chalk outline in as few moves as you can and hit par for three stars. Every level has a proven solution. Get stuck and Show solution plays it for you.
Eighty levels, and a new one every day.
Three chapters bring in charges that blast walls open and holes that swallow blocks. Big Bench and Sweepers come after. Walls shear off anything that sticks out. A fresh daily board arrives every day, the same for everyone. Play with a keyboard, mouse, touch or a game controller.
