Unique - Observation & Concentration Game

Rating: 7.6/10 - 194 votes

Difficult observation and concentration-based game: Unique is a challenging, mouse-clicking skill game based on your keen observation and perception skills. In each quick-fire pictorial level, you are shown a set of near-identical icons (shapes or letters). You simply have to identify the unique ‘odd one out’ among the group, and click on that icon as quickly as possible. Sounds simple, right? Well, it's not really! The catch here is that the various shaped images embedded on the icons can make it extremely difficult to initially pick out any discrepancies between the icons without much closer scrutiny. The sight-testing format combined with the pressure of a ticking clock and other steadily-introduced hindrances make for an exciting eye-teaser!

High concentration is the absolute key to success here. Each set of icons are seemingly identical at first glance, and your focus needs to be at 100% if you want to spot that miniscule difference. This unusual puzzle activity could be used as a ‘concentration training’ exercise for gamers of all ages, or anyone who enjoys a straight-forward problem solving challenge with a twist! OK, let’s test those observation skills!

How to Play: There are 50 quick-fire levels where you must pick the unique ‘odd one out’ from a circular set of similar-looking shapes. All but one of the shapes are 100% identical – and you must click on that unique icon as quickly as you can. The faster you identify the odd one out, the more points you score (Your ultimate goal is to score as many points as you can over the 50 mini-levels). If you click on the wrong icon (i.e. one of the identical-matching shapes), you are deducted points from your total in the top left corner of the game screen. As you progress through the game, the tests become much more difficult. For example, the shapes begin rotating or more shapes are added etc. Enjoy the test!
