|“||Do you want to be a Yandere girl? Do you like stabbing things? Do you like "Idling" games? If you answered "Yes" to any of the above, Yandere Clicker is the game for you!||”|
— The description of the game at KONGREGATE.
The game can be played here. The game is a parody of an addictive game called Cookie Clicker and is essentially played the same way. The player plays as Yandere-chan and every time the player clicks their mouse, Yandere-chan will stab a senpai with a knife. The more the Senpai is stabbed, the more upgrades she can unlock to stab him even more. The game has no end and will continue until the player exits the game.
- This game was created on April 16th, 2014, where the player could only stab the senpai, and nothing else. The upgrades were added on April 19th, 2014.
- As of March 8th, 2017, the game has been updated with an updated character model of Senpai, Yandere-chan now wears black stockings and the player can adjust her bust size with the < and > keys.
- This game brought many people to believe Osana Najimi was Senpai's little sister, but in reality Osana Najimi's original appearance was just used to represent an "Imouto" upgrade that the player could buy. This is not Rival-chan.
- The Time Machine is the most expensive upgrade in the game. The player needs 123,456,789 stabs to unlock it.
- YandereDev would like to make a sequel of this game, called "Headpat Clicker".
