Double or Nothing (1062)

Other names: Loop (Double or Nothing)

Instruction:
Draw two loops that pass orthogonally through centers of cells. At each cell marked with a crossing, either both loops go straight through it, or neither loop goes through it. Each other cell must be part of one of the two loops (but not the other). Neither loop can intersect itself or enter the same cell more than once.
