Discover Unequal

Use each digit once in every row and column. The signs between squares tell you which number is larger. Adjacent mode uses bars to indicate neighbouring numbers that differ by one. Use pencil marks to keep track of candidates. Created by James Harvey for Simon Tatham’s collection.
