Better Sudoku vs Grid

I play a lot of sudoku. After trying most of the apps out there I still hadn't found one that had everything I wanted, so I built it. Classic 9x9 sudoku. Killer sudoku, including 4x4 grids for a quick round. A daily challenge with a new random puzzle every day. Light mode and dark mode, both done properly. Customize the parts that matter to you. The interface is where most of my time went. Every screen was designed to stay out of your way. While you play, the navigation bar disappears so your thumb can reach the bottom rows without stretching. Small things like that add up over hundreds of puzzles. New: A battle mode where you challenge friends live, a rating system to track how you stack up. If you play sudoku every day, this is the app I wanted to exist.

GRIDLOCK is a strategic, grid-based logic puzzle for players who think several moves ahead. There's no timer pressure, no reflexes required, and no luck involved — just pure spatial reasoning and planning. HOW IT WORKS Tap a cell and watch the effect ripple to its neighbors. Simple to learn, but every level adds a new rule that changes how you have to think. TEN LEVELS, TEN DIFFERENT CHALLENGES - Level 1 — Toggle Neighbors: learn the core mechanic - Level 2 — Wrapped Edges: the grid's borders connect to each other - Level 3 — Locked Cells: plan your route around cells you can't touch - Level 4 — Moving Obstacles: predict a patrol pattern before you move - Level 5 — Limited Moves: every single move counts - Level 6 — Multiple Objectives: satisfy several win conditions at once - Level 7 — One-Way Cells: directional tiles that only ripple one way - Level 8 — Number Constraints: cells with values that wrap on overflow - Level 9 — Hidden Cells: uncover concealed information by playing around it - Level 10 — Master Gridlock: every mechanic, combined, in one final puzzle Difficulty ramps up fast — Level 2 is already hard, and it only gets tougher from there. Every puzzle is solvable and has been verified to have a real solution, so if you're stuck, the answer is always findable. FEATURES - 10 hand-crafted, guaranteed-solvable puzzles - Undo and Reset so you can experiment freely - A 3-tier hint system that nudges without spoiling the solve - Move counters, timers, and a scoring system that rewards efficiency - Progress and best scores saved automatically to your device - Haptic feedback you can toggle on or off - Full iPad support with a responsive, scaling grid - 100% offline — no account, no ads, no internet connection required GRIDLOCK is built for players who enjoyed games like nonograms, Lights Out, and sliding-tile puzzles, but want something with more strategic depth and rule variety. Think before you move.
