Sonic Boom: The Telltale Series Season One (often shortened to Telltale's Sonic Boom: Season One or simply Telltale's Sonic Boom) is a graphic adventure video game developed by Telltale Games. Unlike other Sonic Boom games, Telltale's Sonic Boom was released in an episodic fashion, taking place over five episodes that were released over the course of 2018. This series borrows multiple elements from Sam and Max: Freelance Police, including the basic style of gameplay and certain music pieces.
Telltale's Sonic Boom is a 3D graphic adventure game in which the player controls the members of Team Sonic. The player has the character explore the environments of the game and solve a series of puzzles using a simple point-and-click interface. The game's puzzles have logical solutions, although a number of them have far-fetched solutions due to the game's cartoon setting. Depending on the type of in-game entity a player selects using the cursor, the player can have the character walk around an area, look at and comment on objects, pick up certain items or otherwise try to use them. The character may also engage in conversation with non-player characters; when this occurs, the game presents a dialog tree with several subjects to pick from. Topics of conversation may directly involve the story or provide assistance with the game's puzzles, while others may be entirely unconnected.
The game implements an inventory system to allow the character to store any items that the player picks up during the course of the game. The player may select any of the items in the inventory and can then attempt to use them on objects in the game world or give them to other characters simply by clicking on the desired target. Inventory items are context specific, and cannot be used together or combined to create new items.
Each character has a designated inventory item that is carried with them no matter the circumstance, as well as a different icon to represent their inventory:
- Sonic: Carries a ring that he can throw at objects. Inventory Icon is an image of his scarf.
- Tails: Carries a wrench that can be used to fix mechanical objects. Inventory icon is a tool box.
- Knuckles: Carries a roll of sports tape that can be used to grab objects. Inventory icon is a cardboard box.
- Amy: Carries her hammer for obvious purposes. Inventory icon is a handbag.
- Sticks: Carries a boomerang that she can throw at objects. Inventory icon is a survival backpack.
A usual sequence has two or more playable characters in the same area (save for some instances, such as the opening sequence of Episode 1 and most of Episode 4). The player may be required to switch between characters to solve certain puzzles, usually requiring a character's main inventory item, or in situations in which the characters are separated.
The characters can travel between a variety of locations in the game using a Map that each one of them carry, which, when selected, will present the player with a list of available destinations that vary between episodes:
- Sonic's Shack (All Episodes)
- Tails' House/Workshop (All Episodes)
- Knuckles' Hangout (Episodes)
- Amy's House (All Episodes)
- Sticks' Burrow (Episodes 1-4)
- Village Center (All Episodes)
- Meh Burger (Episodes 1-4)
- Eggman's Lair (Episodes 1, 3 & 5)
- Eggmanland (Episodes 1 & 4)
- Top-Secret Planning Area of Totally Non-Evil Plans (Episode 4)
- Mount Safety (Episodes 2 & 4)
- Big Boy (Episode 2)
- Cargo Hold
- Engine Room
- The Future (Episode 5)
- Tails' Workshop/House
- Sonic's Shack
- Knuckles' Hangout
- Junkyard (Sticks' Burrow)

Like most of Telltale's other games, action sequences are carried out through cinematic quick time events. Though not all QTEs need to be successful to advance (except for QTEs that result in death if failed), succeeding in enough of them will allow the character to preform a Finishing Move at the end of a fight.
Telltale's Sonic Boom also features sequences called Corridor Runs, where the player manually controls Sonic as he runs automatically down a long three-lane pathway, and must avoid obstacles and complete occasional QTEs to reach the end or defeat a certain enemy.
Episode 1: "The Big Boom"
- "When a drought of Eggman attacks leaves the village, including Sonic and Co., in an alarming state of boredom, they turn to Eggman's new amusement park to cure the boredom."
- —Rough Synopsis
Episode 2: "Knuckle Duster"
- "Eggman has unveiled a new series of mech suits, and while Sonic and company would normally have no trouble with them, ol' Egg face always seems to be one step ahead this time..."
- —Rough Synopsis
Episode 3: "Eggman In Chief"
- "It's almost Election Week in the Unnamed Village, but Mayor Fink has gone missing! Not only that, but Eggman seems to have taken a sudden interest in politics, and now he's running for office! Coincidence? We think not!"
- —Rough Synopsis
Episode 4: "Ludonarritive Dissonance"
- "After an endless series of attacks on the village, surely no one's gonna believe it if Eggman suddenly says he's going straight-- Nope, everyone believes it."
- —Rough Synopsis
Episode 5: "Shadow of the Past"
- "A startling revelation sends Sonic and friends on a 5-person manhunt that will only end with the location of one person: Shadow the Hedgehog."
- —Rough Synopsis
- Everyone failing to open the door to Tails' Workshop by pushing on it and complaining about it, only to be told to "try pulling", which always works. Tails himself ends up falling victim to it in Episode 5, when he tries to open it from the inside by pushing after being sent into the future, where the door opens from the inside.
- The contents of the bookshelf in Amy's House changing each episode. In Episode 1, the shelf is stocked with multiple copies of Sonic's Autobiography, in Episode 2 it's filled with crossword and coupon books, in Episode 3 it's filled with books about politics and law, while in Episode 4 it's filled with copies of Eggman's Autobiography (required for a puzzle). The shelf is empty in Episode 5.
- References to the infamous "Bounce Pad" quotes from Rise of Lyric whenever one is used for a puzzle. When Sonic comes across one in the Village Center Episode 1, he cuts himself off mid-sentence and awkwardly decides to "keep his mouth shut", looking directly at the camera as he does so. Knuckles does something similar when finding one in the Big Boy's cargo hold in Episode 2. Finally, when Sticks needs to use one during the climax of Episode 4, she comments that she feels enraged when she says its name for some reason.
- Tails letting slip that he's working on a "top secret pet project" and denying anything about it when asked further. The project is revealed in Episode 5, and is revealed to be a time machine. This kicks off the plot when Sonic and Tails accidentally send themselves to the future while fighting over it.
- Despite only being accessible in Episodes 2 & 4, Mount Safety appears on the map in all Episodes, with a note next to it reminding of how dangerous it is, which, when clicked on, will lead to the characters giving a theory on why it was named as such. Sonic & Knuckles theorize that it was opposite day when it was named, Tails & Amy believe that the person who named it simply had a sick sense of humor, and Sticks rambles off an absurd conspiracy theory about the name.
- References to Amy's novel, "A Rose Without Thorns', and various adaptations of it that she's not aware of. It's first mentioned as being a bestseller among "single parents and lonely nerds" in Episode 1. This is the only time Amy's aware of it, stating that Tails bought a copy (which puts him in the "lonely nerds" category). She finds out that it's been made into a TV special in Episode 2, a video game in Episode 3 (of the "lame walking and talking simulator type" as Knuckles puts it) and a Summer blockbuster in Episode 5. Humorously, the poster for the movie is present in the same place in both the present and the future, leading Sonic to comment on the movie's long production time. Amy also mentions working on a sequel to the book in Episode 4.
- Characters being required to use an outdated device or object and someone stating "they still have those?" when being told of it. In Episode 3, Sonic is required to call Orbot while impersonating Eggman (long story), claiming to be using a phone booth to explain the lack of Caller ID (he's actually using the landline in Sticks' Burrow). In Episode 4, Amy claims that she and Knuckles took the bus to Eggmanland, leading to this response from Sticks.
