Product Description

A stream of deadly Q-Viruses is taking over the universe by exterminating any sign of life that gets in the way! There's only one way to save civilization-crack the Q-Virus' DNA Code and obliterate them all. In "Double Sequence," players shift and slide blocks of the random genetic code in order to match like colors. This will not be easy-the patterns become more difficult as the Q-Virus ravaged more planets.

This review is from: Double Sequence: The Q-Virus Invasion (Video Game)

Overview: Colored, blank and immovable blocks in various patterns are displayed across both screens. Your goal is to group a specified minimum number of a single color together in order to detonate them off the playing field. Once all colors of blocks are gone, you have solved the level. For most of the puzzles, there usually are many possible solution paths you could take. The challenge of the game is to find an efficient solution path, for which the game will award you medals.

The blocks on the two screens are connected in the way that if you scroll either left or right a certain number of columns on the bottom screen, those columns of blocks will appear on the top screen scrolled the same number of columns but in the opposite direction. In this way, the whole playing field is always visible. You move blocks within their initial pattern by transferring them between the two screens. You do this by pressing down on a block and then, as long as that block's counterpart on the top screen isn't an immovable block, that one plus every block above it on the bottom screen will switch places with those in the inverse position on the top screen.

Pros:

Solving these puzzles well enough to medal, will challenge your spatial reasoning skills.
Time and number of attempts is recorded for each puzzle.
While time is recorded, there is no time pressure during the actual puzzle since whether you earn a medal depends solely on how few moves your solution takes.

Cons:

The main menu for the puzzles is convoluted with too many selection layers and too much descriptive text and pictures that do not have any real connection to the actual puzzles.
Before solving a few specified puzzles sometimes you have to 'scan' it , which in essence is mostly busy work before you can play the actual puzzle.
No preview of the puzzle before you click to play it.

Comments:

Fortunately the developers gave us an alternative way to keep track of the puzzles through the Progress menu which you can click on from the main intro screen. Here all the puzzles are each represented by blue squares with different colored shapes on them depending on whether it is unsolved, unsolved and needs to be scanned, solved but not efficiently enough for a medal, or solved well enough to earn a bronze silver gold or 'alien' medal.

If you enjoy having to think deeply to figure out abstract puzzles, then this is a great game to get.
