KakuroStep: Kakuro Coach

KakuroStep is an offline Kakuro puzzle game and step-by-step Kakuro tutor in one.

Solve number-crossword puzzles by filling each run with distinct digits that add up to its clue. When you get stuck, open the logic Coach. Instead of simply revealing an answer, it shows where to look, which candidates remain, and why the next move is forced.

LEARN KAKURO STEP BY STEP

Start with clue cells, across and down runs, and the no-repeated-digits rule. Continue through remaining sums, unique combinations, crossing eliminations, hidden singles, required digits, and pairs. Academy progress and practice results stay on your device.

HINTS THAT EXPLAIN WHY

Coach uses a structured clue ladder. It can highlight the relevant run, name the technique, explain the candidate change, and show the logical deduction. The move is applied only when you choose. Every explanation comes from deterministic Kakuro rules, not from an answer lookup.

PUZZLES YOU CAN TRUST

Every included puzzle is checked for one unique solution. No-Guess Certified puzzles can be solved from a blank grid using the same human-style techniques that power Coach.

PLAY YOUR WAY

Choose a difficulty, enter digits quickly, keep your own pencil notes, and continue exactly where you left off. KakuroStep works offline and stores puzzle progress, learning progress, settings, and statistics locally on your device.

Learn Kakuro. Don't guess.
