Difference Find Master Game

A straightforward version of the format, Difference Find Master Game shows you two images per level that look almost the same. Several small details have been altered between them, and your task is to inspect both pictures, find every change and complete the level before the time runs out.

The developer stresses that the changes can be anywhere in the images, including the corners, so there is no safe area to skip. That is the main piece of advice the game gives about itself, and it is a fair warning, because with a timer running it is tempting to look only at the obvious parts of a picture.

It is played entirely with the mouse. The developer does not give a level count or describe particular themes for the images, so what you get is the core puzzle: compare, click, beat the clock.

Compare the two images on screen and look for details that do not match. Use the mouse to click on each difference you find. Several details are changed in every level, and they may be anywhere in the pictures. Find all of them before the timer runs out to complete the level and carry on to another pair.

Take the warning about corners seriously. Before the clock gets tight, run your eyes around the outer edge of both pictures, since those areas are easy to neglect. Then work inwards. A methodical pass costs a few seconds and saves the frustration of a missed change hiding in plain view.

A timed spot-the-difference game played with the mouse. It uses a 4:3 landscape frame (800 by 600). The developer says differences can be hidden anywhere in the images, so every area of each picture needs checking.

Spot The Difference Wild West is another timed comparison, set in cowboy towns and desert scenes with hints to fall back on, and Mystery Campus Spotter adds a choice of difficulty levels and college campus settings.
