Serving Club Activities Episode: Trial Lesson

Serving Club Activities Episode: Trial Lesson (or The Lusty Club Activities Time: First Lesson) is a hentai-themed tile-matching puzzle game with a storyline set in a near future where society is threatened by a declining birth rate. The protagonist is a male student who is tasked with using his stronger-than-usual sperm to impregnate women, starting with the school nurse, Mio Manabe; the head of the maid club, Hikari Fujino; and the head of the cooking club, Momoka Inoue.

In this tile-matching puzzle game, the player must swap any two adjacent tiles in a randomly-assorted grid to create a row of three or more identical tiles. Rows of three or more tiles will disappear once created, causing the tiles above them to fall down into the empty space. Creating rows of three or more tiles will cause damage to the current opponent of that level (one of the three women in the game), causing their clothing to become more revealing. The player can also use special skills and items to damage their opponent until she is defeated. The opponent can also damage the player character between turns, requiring the player to think strategically about which tiles to eliminate. Some tiles, such as the Recovery Orb which restores the player's health if it is kept in the grid, are advantageous to keep in play.

Currency earned from completing objectives can be used to purchase skills and upgrades between levels. Sex scenes are unlocked as the player progresses through the game and can be revisited from the main menu. There is also a gallery feature where the player can view the character sprites and customize them by changing their expression, accessories, clothing, and background. The game features Japanese voice acting for the three female characters.
