With Double Sequence, DSI Games adds another offering to the growing list of casual puzzle experiences available on the DS today. However, the game as a whole is a lot more than initially meets the eye, and with a complex gameplay system, it actually caters to a very specific set ? those that enjoy tons of challenge with a side dish of fun.

In Double Sequence: The Q-Virus Invasion, an outbreak of deadly diseases has begun to spread across the universe decimating everything in its path. It is up to you to analyze the specific DNA sequence of each virus and destroy them one by one.

Gameplay takes advantage of both the top and the touch screen. Twelve columns of colored blocks line up on both of the screens, and using your stylus, you switch the position of blocks (or chunks of DNA) either individually, or by switching the entire columns at once. To make this a bit clearer, you are essentially moving blocks on the top screen to the bottom, and vice versa, with the goal of connecting as many like-colored blocks as you can.

Once you've made large enough groups (the number of blocks being determined by each particular virus) you can destroy them and continue on. Adding to your options are special multi-colored blocks that can connect with any other color, and the fact that you can also move the game board left and right, with the top screen's columns cycling to the bottom and the bottom's cycling to the top.

While this may already sound complex in words, I don't think I could accurately describe the difficulty found here. Perhaps it is simply because of my mind's configuration, but when each level contains almost infinite choices in terms of moves, finding a way to eliminate every last block from the screen becomes a frustrating and seemingly impossible task.

However, for those that do have a better ability to plan eventual moves in their minds, clearing the game's 30 planets should provide more than enough action to keep them satisfied. If you're like me though, all of the retrying you're bound to do might wind up forcing you to look elsewhere for addictive puzzle goodness.

If this is the kind of game that does something for you, you'll be happy to hear that there are a couple of extras found throughout, such as the ability to create your own strands of virus DNA, and the ability to share those designs via the DS's Wi-Fi capability.

Even though the game's difficulty may be enough to scare some people off, I highly doubt anyone will pass on the game because of the technical side of things, as the graphics are beautiful. Each virus and planet is highly detailed, and when mixed with the brightly colored puzzle blocks, you're met with a treat for the eyes. Likewise, the music is futuristic, with a mix of techno beats and electronic sound effects that's sure to have you playing with the volume at 100.

All in all, Double Sequence: The Q-Virus Invasion is definitely not for everyone. For those that can see things from a more 3D perspective, the challenging puzzles found here are sure to please; however, for the more literally minded of us (who see things the way they are, and not the way they might be), you might look elsewhere in DSI's lineup for addictive puzzle gameplay. Either way, this is one game I suggest renting first just to be safe.
