Things start to get really interesting with pairs in "Tango".

Turn on the unique and innovative highlighter tool to visually search for patterns like box-line reductions, hidden sets, X-wings and more without the tedium of scanning for individual pencil marks across the grid.

All puzzles are guaranteed to be solvable without guessing and have one unique solution.
