Escape Whisper Valley
Escape Whisper Valley, offered on PopCap Games, is a challenging I Spy game for adults. The premise is you are trapped in the village of Whisper Valley due to a rock slide. You must search 25 scenes of the village to spy 10 objects in each. Additionally you must locate a lock and key in each area. After you find all 10 items in one area, you will collect a piece to a map that will help you escape. Between each round you must solve a puzzle. The objects that you must spy are hard to spot, sometimes narrow in size or camouflaged within the background. For some items, names will not be provided, but instead you must decipher clues. For example, if "cleans ears" is on the search list, you may have to find a cotton swab. Additionally, there is usually one task on the search list, such as "replace the missing numbers," which means you have to find the missing numbers and then find where they belong. You can download Escape Whisper Valley, and other hidden object spy games, from the PopCap Games site for a free trial that lasts approximately 45 minutes.
The Clockwork Man
The Clockwork Man is another online I Spy game for adults, fit for the intellectually gifted. You will travel around the town of New Conventry, finding hundreds of hidden objects that have been hand painted for the game. Each spying scene appears almost three-dimensional and has the option of either zooming in and out, or scrolling left to right. The objects you have to find are sometimes half-covered and knowing what they look like is sometimes discerning. Luckily the robot Sproket can provide you with hints, although these are limited each round. The game follows a story line which includes solving puzzles, some of which are mechanical in nature. For instance, at one point you need to find all the items and then figure out how to use them to repair a ship&'s engine. You can download a free trial of the Clockwork Man for an hour period.
