## Description

Every hint teaches you the technique to solve it yourself — never just the answer. Classic & Killer Sudoku, fully offline. Pay once. No ads, no tracking.

Gridwell is Sudoku that actually makes you better at Sudoku.

Most apps hand you the answer when you're stuck. Gridwell teaches you the technique instead — it shows you the next logical step and names the strategy behind it, so you learn to spot it yourself next time. Every puzzle is solvable by pure logic. No guessing, ever.

CLASSIC & KILLER SUDOKU
• Hand-crafted Classic Sudoku across four difficulties: Easy, Medium, Hard, and Expert
• Killer Sudoku with cage sums for a deeper challenge
• Every puzzle is guaranteed to have one solution and to be solvable by logic alone

HINTS THAT TEACH

• Learn the "why," not just the "what"
• Three free hints on every puzzle

PRIVATE BY DESIGN
• 100% offline — play anywhere, no connection needed

• Your progress stays on your device, always
