Tokimeki Memorial (ときめきメモリアル, lit. "Heartbeat Memorial"), also known among fans as TokiMemo, is a dating simulation series by Konami with the first game released in 1994. It consists of few main games and many spin-offs. The games are notable in the dating sim genre for being highly nonlinear.
The gameplay focuses on scheduling, dating, and stat-building as the player has limited time to allocate between asking out members of the opposite sex and develop the playable character's abilities at school and sport. There are brief, but frequent dates, with usually only one multiple-choice question to determine whether the partner's love meter will increase or decrease. One playthrough lasts for a fixed period of three years of high school, at the end of which the character with the highest love meter confesses their love.
