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.

Ratings and reviews

I love this key lock game. The graphics are nice and some levels are really challenging. Helps me keep my mind sharp and allows me to also relax at the same time.

This is such an amazing game. The graphics were beautiful before, and with the recent update - they are even more crisp. Ads are minimal, which is rare these days. This is definitely one of those games that I play every day.

the game is black. I tried to load in and when it shows me the locks and stuff the whole screen is black and I try to reload the game and everything but it wont load.
