 Upon its release, "Russian Roulette" received generally positive reviews from music critics.Jeff Benjamin of "Billboard" opined that unlike the "straightforward, in-your-face bubblegum" their past singles "Ice Cream Cake" and "Dumb Dumb" delivered, "Russian Roulette" brings a different flavor, incorporating 8-bit and arcade-inspired sounds into the mix and has "repetitive, nearly robotic-like hooks that are just as addicting as their past bangers".Writing for "The Daily Dot", Sherly Tucci called it a "cute and bubbly song complemented by the bright colors of the music video".
