## What is PlusGrid?

PlusGrid is a cozy number puzzle — a relaxed mix of Sudoku, Kakuro and Killer Sudoku.

  Fill the empty cells with digits so that every row adds up to the number on its left, and every column adds up to the
  number on top. Just like Sudoku, no digit may repeat within a row or a column. Each puzzle uses only a small set of
  consecutive digits.

  • Three grid sizes: 3×3, 4×4 and 5×5
  • Three difficulties — from a quick warm-up to a real brain-teaser
  • Pencil-mark notes, hints, and unlimited undo
  • A timer, streaks and per-mode best times
  • Light and dark themes
  • A short interactive tutorial for new players
  • English, Russian, Spanish and French
  • Plays fully offline — no account, no ads, no tracking

  Perfect for a few quiet minutes on a break, a commute, or before bed. Just you, a tiny grid, and a satisfying click
  when every line turns green.
