When you start the game, your Marker will be at the bottom, middle of the playing screen. It is now up to you to start creating boxes. Keep in mind that you need to be constantly moving or the Sparx will take out your Marker. In addition, when you are moving your Marker around the perimeter, you can only move along the perimeter actually touching the Playing Field.
First of all, you must be constantly aware of two things. First, you must know where the Qix is located at all times. It moves randomly and can go anywhere on the Playing Field that your boxes haven't blocked. Last, the Sparx are constantly moving around the perimeter of the Playing Field. This can set up a dangerous situation where one Sparx is coming at you from one way and another from the other to make your Marker a 'Sparx Sandwich'.
Once you have assessed the danger, it is time to start making boxes. There are a few things to note when you are making boxes :
a) When you start to draw the line, the Sparx cannot travel along the new perimeter you are creating until it is filled in.
b) The Qix, though, is your primary concern. If it touches any part of a line before the box is filled in, you will lose your Marker.
c) The box must begin and end either at a filled box or on the side of the Playing Field. You cannot connect the line to itself. If you try to do this, you will go into what is called a 'Spiral Death Trap' and a Fuse will follow your line to your Marker and destroy it.
After the fourth wave, the Qix will split in two. Now you have 2 Qix's bouncing around to deal with. You major goal is to actually 'split' the Qix's into their own areas. This means creating a series of boxes so that each Qix will be in its own compartment.
For maximum points, you must do two things :
a) First, use the slow button as much as possible since this is where the points are.
b) Try to claim as much area in each box as possible. That percentage multiplied by the speed value can yield some big point values.
c) Constantly try to split the Qix's (if you can) to get that bonus multiplier even higher.
d) When you are close to the Threshold, find an area in the Playing Field that hasn't really been touched and try to make a big box. That way, you will go over the 75% Threshold and claim a bonus.
As the waves progress, everything gets faster and the game will become less forgiving if you are less then committed to making a box.
Also, listen for sounds in this game. The only real sound you need to be concerned with is what sounds like a fuse being lit. If you are making a box and you hear this sound, that means you are taking too long or you have unfortunately gotten yourself into a 'Spiral Death Trap'. In the case of delay, once you move the fuse will go out.
To maximize points, draw narrow, tall boxes, like fingers, from the bottom. When the Qix goes down between two fingers, go across the top of the fingers at slow speed. This tactic permits percentages of up to 99%.
It is possible create a 'slide-box' to avoid the sparks. Starting at a corner of a box, draw another box that connects only at that corner. When a spark approaches, the player can slide the diamond through the intersection, while the spark has to go around the perimeter. After the spark passes the intersection, the player can slide back across the intersection and be behind the spark.
