## What is Grid?

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.
