Classic Mario puzzler Dr. Mario is making it's way onto the 3DS eShop this week. This 3DS edition is the Game Boy version of the NES title where Mario attempts to kill viruses by matching the correct coloured pill to the virus.
Much like Tetris, the pace quickens significantly as the player progresses further, thus posing a tough, but still incredibly addictive, challenge.
Now to honour the occasion, check out brentalfloss'Dr. Mario WITH LYRICS.
