Emerald Thief Instructions

After it loads, click the "PLAY" button on the lower right of the game.

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!

GAME TIP #1: Many games on this site such as Curveball were built with Adobe Flash. To play these games, you must allow the free Adobe Flash Player to run in your browser. If you don't see an animation in the red rectangle above, click in the red rectangle and activate your Flash Player. Then the Flash-based games should open for you.

If you see a message that the Adobe Flash Player is "blocked", go to your browser's Settings page and change Block to Ask First, if possible.

If the red rectangle is empty, your browser might not have the Flash Player. To check this, follow the steps on Adobe's Flash Player Help page.

GAME TIP #2: If you cannot get the Flash-based brain games to work, try the HTML5 brain games instead. HTML5 games do not use the Adobe Flash Player. They work in modern browsers automatically. All the HTML5 games are listed on this page.
