In the Boxlights game screen, pictured here, the left box represents the amplitude of EEG activity within the low frequency inhibit band; the right box represents the amplitude of the high frequency inhibit band activity. The middle box represents the medium frequency (reward band) amplitude. These boxes correspond directly to the bottom three traces on the therapist"s station in 5-trace layouts. A white outline square appears for the reward box. This represents the goal for the band. If the client makes the middle colored box bigger than the white square and keeps it bigger for half a second, while keeping the two outer boxes from touching the white square, they are rewarded with a beep and a score. For 6-trace-with-inhibit layouts, the left box is a rectangle with the horizontal width proportional to the topmost inhibit trace amplitude and the vertical height proportional to the next inhibit trace amplitude. 6-trace-with-reward layouts have the center box width proportional to the upper reward trace amplitude and the height proportional to the next reward trace amplitude. For 8-trace layouts, the horizontal widths are functions of the top set of inhibits+reward and the vertical widths are a function of the lower set of inhibits+reward.

The colors of the boxes in classic mode are consistent in this and several other games. The low frequency box at the left is magenta; the high frequency box at the right is yellow, and the center box is blue for SMR training and green for beta training (as controlled by the therapist).  In the modern mode, the box colors are fixed and the entire background is set based on the current image being displayed in the center box.  The image changes at the end of each period.

The goals for the low and high frequency inhibit bands are represented by their distances from the white square. If one of those boxes grows big enough to overlap the white square, rewards are not given. Thus the objective for the client is to make the middle box big and the outer boxes small - that is, to increase amplitude in the selected intermediate frequency (Alpha, SMR, Beta) and reduce amplitude in the outlying frequencies.

The therapist can adjust the relative sizes of the boxes in the Boxlights game by adjusting the scales of the three traces on the therapist station screen.  Classic/modern is selected in the game tailoring options.
