Kakuro Grid
Cross sums without the guess
Every puzzle in Kakuro Grid is proved to have exactly one solution and is solved end to end by the same logic engine that powers the hint button, before you ever see it. Boards from 6×6 to 12×12, three ways to play, and the puzzles need no connection.

Combination helper — tap a clue and see every digit set for that length and sum
Notes like on paper, unlimited undo, and a bookmark to try a branch and jump back
Classic, Journey and Daily — 6×6 to 12×12, from Easy to Expert
A techniques school that teaches the logic one move at a time
Game Center leaderboards and achievements, best times for every size
