Grid-Lock

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.
