Emerald Thief Instructions

Try to steal the valuable emerald from the museum. Avoid detection while locating keys and then the emerald itself. If any of the security devices touch you, it's game over!

If you like this game, you might also want to try the Sneak Puzzle game.

HOW TO PLAY.  Carefully check the map of the museum. To complete the game, you must reach the Emerald Chamber and steal the precious jewel.

Collect keys to open the closed doors. The color of the key matches the color of the door.

The precious emerald is, of course, green. Steal the emerald and escape from the building before the cops arrive.

Use the Arrow keys to move. Stay alert and avoid the laser beams, robots, and cameras to avoid being caught.

HINT: Check the map if you get lost. Pay attention to special instructions that appear in the lower left corner.

I hope you enjoyed playing Emerald Thief!

Good work Andy!!  You are one in a million.
