The player must defeat waves of enemies in turn-based battles, located within stages, in order to progress forwards and unlock new stages. Each of the characters have a total of six attributes that determine their combat effectiveness: HP, agility, yin attack, yin defense, yang attack, and yang defense. Additionally, each of the characters have multiple spell cards, which can be used multiple times per stage, and one last word – the last words are more powerful than the regular spell cards, but if they are used, regular spell cards can no longer be used that stage. Story cards are items that can be equipped to further empower spell cards, as well as improve the characters' attributes. Characters can also level up by engaging in services, such as attending a school or dojo. Completing these services will earn the player coins, which can be used to upgrade their characters, or acquire new ones. Services are also a primary source of spirit power – the game version of gacha stamina, which is required to perform any task in the game. As part of the game's gacha system, the player can purchase coins and spirit power through in-app purchases.

In Touhou LostWord, the "Lost Word Incident" occurs, causing words to go missing, which threatens the stability of Gensokyo, and leads the characters to investigate by travelling across multiple different universes to find the lost words.
