SVD

SVD is the 2022 edition of Google's annual puzzle, used to announce the dates of I/O, its yearly developers' conference. "SVD" is an abbreviation of "singular value decomposition," and players who arrive at the website are shown a series of tangled strings that they must untangle into circles using algebraic principles. The game has an audio component, requiring players to use the notes and beats to deduce the numbers needed to change the color and shape of the circles. There are four puzzles total.
