About this game

Lock Jam is a puzzle game where you drag keys through a board, matching them to their same-colored lock, but watch out! Keys block each other’s paths, forcing you to strategize every move.

How to Play:
Drag & Decode: Slide keys through the grid to reach their matching locks. No overlaps allowed, plan wisely!
Match to Unlock: Connect each key to its color-coded lock to clear the board. One wrong move? Time to backtrack!
Think Ahead: Tackle escalating challenges from simple 4x4 grids to mind-bending 8x8 mazes.
