4th Logo (September 10, 2000)
Visuals: Continuing from the custom Simon & Schuster Interactive variant is particles of that logo come together on a moving space background to form a different cross figure on a white circle. The bars appear to be spikier, and the one leaning to the left is styled in 3D. Then the letters of "HYPNOTIX" zoom out below the logo and glow.

Technique: 2D computer animation.

Audio: A rising synth note, followed by a woman gasping and a ding as the letters glow

Availability: Only seen on Panty Raider: From Here to Immaturity.

5th Logo (April 13, 2001-August 26, 2005)
Visuals: On a black background, a striped ball appears spinning and zooming out in static, then it gets hit with a thunderbolt. The bolt's energy lights up the word "HYPNOTIX" with a and  border (the ball replaces the "O"), which then all zooms in fast and disappears.

Variants:
 * On The $100,000 Pyramid (the first game with this logo), the logo zooms out and stops in the center, then glows and shines from left to right.
 * On Deer Avenger 4, the logo is seen with a shadow copy of the "O" spinning in the background.
 * On Outlaw Golf and Math Missions, the logo pulsates and releases shadow copies of itself.
 * On BMX Trick Rider for the Game Boy Advance, the logo is still.
