It is very similar to The Sims in that the player is responsible for characters who have to be taken care of, such as by ordering them to eat, sleep, go to work, etc.
The game is available for sale via download from the company's website, with payment required to continue playing after the one-hour time limit was up. In Australia, it was banned by the OFLC as it had exceeded the highest allowable rating for video games, which was MA15+. It has been debated as to whether or not an R18+ rating (which currently applies only to films and DVDs) should be introduced for video games.
The CD-ROM version sold in the USA censors any nudity throughout the game.
Comparison to earlier games
Singles was largely panned by critics for being a rip-off of The Sims and the way it offered little challenge, with the player required to simply follow a routine of making the characters progress from making small talk through to professing love then running off to bed together via the simple interaction menus. The 'needs' are also considered fairly inconsequential, with the characters never starving to death even when their 'hunger' need has dropped to zero.
A sequel, titled Singles 2: Triple Trouble, was released in June 2005 and featured three housemates instead of two.
Singles: Flirt Up Your Life -- Extended Version is a Mature rated version of Flirt up your life.
