The main plot is always to find items to advance to higher chapters. Also, there are items called "puzzle pieces" which allow interaction with other characters, items, and animals. In the first two games, the objects are broken down into pieces and scattered throughout the different sections of chapters. In the third game the only difference is that pieces are not broken down, making it more like an I spy game.
The four games are:
- Mortimer Beckett and the Secrets of Spooky Manor, in which Mortimer helps his uncle to get rid of ghosts, by retrieving pieces of the Ghost Machine which have been hidden all over the manor. The cut scenes are 2D and read like a comic book. This game has also been made into a game for Nintendo Wii and into an application for the iPad.
- Mortimer Beckett and the Time Paradox, in which Mortimer has to travel through time to retrieve pieces of a timebomb that fell through a portal in his uncle's manor. The cut scenes are 2D, in which Mortimer falls into the next timezone.
- Mortimer Beckett and the Lost King, in which Mortimer wakes up from his final travel through the time portal from the Time Paradox game and learns he has to find the eight jewels of a powerful crown, with which he can locate the kingdom's lost king. The cut scenes are 3D, in which Mortimer walks towards the next scene.
- Mortimer Beckett and the Crimson Thief Finally home after his journey, Mortimer resumes his simple life and peruses the daily newspaper. He finds that a mysterious figure named the Crimson Thief has been stealing valuable art pieces from all over the globe, while eluding the police at every turn. Mortimer jumps on the case and is determined to find the stolen goods. Mortimer travels all over the world to recover stolen items: Paris, Rio de Janeiro, London and other destinations, looking for usable items, solving puzzles, and meeting and assisting the locals. At the end of the game, the song "Mickey" by Toni Basil is played with a cutscene in which Mortimer is dancing with cheerleaders.
- Mortimer Beckett and the Book of Gold The Upcoming Game is set to release in 2017. In this game, Mortimer goes on another adventure, joining with Kate O'Malley of Delicious (game series).
