Aurora SlantDiagonal logic rules

How to play Slant.

Put one diagonal line in every cell, match the numbered corners and never make a closed loop.

Two choices per cell: every square contains either / or \.

How the clues work

A number sits on a corner shared by up to four cells. It tells you exactly how many diagonals must touch that corner. A 0 rejects every touching diagonal; a fully surrounded 4 requires all four.

The no-loop rule

Even when every number is satisfied, the connected diagonal lines may not form a closed circuit. If one placement would close a loop, the cell must lean the other way.

Good first moves

Fill corners with 0 clues first, then maximum clues such as a corner 1, edge 2 or centre 4. After each placement, reduce the remaining count around nearby clues. The puzzle becomes easier when you treat each line as information for several corners at once.
