This is volume 1 in a series of hard TripleCross puzzles.
A TripleCross is like a crossword, but it uses numbers instead of letters.
Each digit occupies a hexagonal cell and can be part of a “word” in the across, up, and down directions.
Each clue is a mathematical relationship with other clues. For example, a puzzle might have the clue that 1 Across equals 4 Up plus 6 Down.
