RIP Scary Math Teacher is Killed Dies Dead Grave is a free simulation game available on Android developed by Cyan Crab. The game is set in a school where the math teacher, Baldi, has been killed by mysterious black creatures. The player's objective is to find the last 7 deadly notebooks and 9 dies notebooks to get Baldi's ruler and attend his funeral procession.

The game's storyline is centered around solving math problems to save Baldi, but it is impossible to answer the second math equation from the YCTP math question machine. Witnessing Baldi's death can be a scary and emotional experience for some players. The game's graphics are not very impressive, and the controls are not very intuitive. Overall, RIP Scary Math Teacher is Killed Dies Dead Grave is a mediocre game that may appeal to fans of horror games or those who are interested in math education.
