Unlike the prior Brain Age games, It was released in North America, and was later released in Asian countries, Europe, Australia, and South Korea.
The game retains it's format of featuring a variety of activities including stroop tests and mathematical questions. Some are from past games from the series while some are brand new. These activities are all designed to help keep certain parts of the brain active. Though it still utilizes the touch screen, the game does not support the microphone. But it supports Joy-Con motion controls.
The main brain trainer of the game, Dr. Blushy, was tired of being a doctor whose job is only to throw pills to viruses to kill them, and wanted to study the human body as a whole. But he did't know where to start and decided to take a look at Dr. Ryuta Kawashima's work in the neurosciences to get started, and found out that solving simple math problems rapidly and reading out aloud uses a lot of areas of the brain, and then suddenly thought of the Numberblocks and the Alphablocks. So he teleported to Numberland, where the story was taking place. One and Two are talking about how peacful their recent days are, but their dialogues are interrupted by Dr. Blushy. Dr. Blushy then explains everything mentioned above, and how he discovered Brain Age to train his brain before he went into the video game world. He then shows his pal, Four to One and Two, and then proceeds to use 5 brain training activities (Namely Calculations x 20 (Math), Word Scramble (Language), Head Count (Concentration), Train of Thought (Reaction) and Low to High (Memory)) to test the player's Brain Age. After the Official Brain Age Test, a familiar voice was heard, which belongs to Wattson, Dr. Ryuta Kawashima's partner in Body and Brain Connection . After Dr. Blushy made friends with Wattson, the player is led to the main menu.
After the player unlocked all exercises, there will be a short movie. In the movie, The Characters thanks the player for staying with them, and then a familiar voice is heard again. It comes from Dr. Ryuta Kawashima, with his body! It turns out that he was spectating the characters from the Japanese University he is studying, and then says that they are great descendants of his job of being a brain trainer, and he shall focus on studying the human brain. A picture is taken before Dr. Ryuta Kawashima leaves. While looking at the picture, Blushy expresses that he likes his new job. And then Dr. Blushy said that there are more people to thank for this, and proceeds to show the credits at the Brain Tip Cinema, and everyone watched it.
Classic game modes, such as Brain Age Check, Brain Training and Sudoku have all made a return to the game.
Brain Age Check
Unlike the first two Brain Age games (even Body and Brain Connection), the game picks 5 brain training activities (disincluding Devilish Training activities), which consists of one Math game, one Language game, one Concentration game, one Reaction game and one Memory game to test the player's Brain Age, similar to the format of Big Brain Academy. This will explain why the activities from Brain Age Check in the past games are directly playable in the Brain Training game mode. At the end of the Brain Age Check, the game reports on the players "brain age", a theoretical assessment of the age of the player's brain. The higher the brain age, the worse the player performed. The game still uses the system which lowest possible age is 20, according to Kawashima's theory that the brain stops developing at 20.
One major difference is that the result screens will have a 50% chance of making Fake-outs. In a Fake-out, a false age will be shown, and then Four will screech at the wrong digit. The digit will then fall, and the right digit will drop, forming the correct Brain Age. This most likely happen if a player gets a Brain Age of 20. However, fake-outs can be toggled on or off in the options.
If played locally with one Switch console only, there are 2 modes, namely Official Brain Age Test (for 1 player only) and Competitive Test (for 2+ players). Multiplayer is also possible by connecting 2+ Switch consoles.
The Training mode still allows the player to play a variety of puzzles. Once the player logs into the game (even without playing any puzzles), Dr. Blushy awards him or her with a stamp, which he places on the current date. If the player plays at least three puzzles, the stamp will expand in size. After accumulating a certain number of stamps, Dr. Blushy will award him or her with a new puzzle, difficulty mode, or additional feature under the Options menu. Each puzzle can be played as many times as the player likes, although only the first play-through of the day will count in the graph for that puzzle.
Players can select to be ranked with vehicle metaphors or a letter (S-E) in the options. If the player's time or score in Brain Age Check or Training is high enough, it will appear on one or both of the Top Three. The Top Three shown is the player's own top three attempts at a puzzle, while he or she can also compare the top three with those of other saved players.
A new function estimates a player's Brain Age by looking into the results in a single game. However, said function is not included in Devilish Training.
Training Programmes are divided into Math, Language, Reaction (which trains people to react to a situation correctly), Concentration and Memory.

Sudoku is back after Concentration Training! As always, this features more than 100 puzzles across three different modes – Beginner, Intermediate, and Advanced. Sudoku involves a 9×9 grid with numbers in every square. Some of these numbers are visible, while others are not. The objective is to fill in the hidden numbers using the visible numbers as hints. Each row, column, and 3×3 grid has nine squares in it, and each must contain each number in the range from 1 to 9.
A new game mode exclusively for Brain Age Deluxe which also contains 100 puzzles of 3 different difficulties: Beginner, Intermediate and Advanced. Tectonic involves a rectangular grid with uneven small areas divided. Each area must contain each number in the range of 1 to N, where N is the number of squares in an area. In addition, no number must be adjacent (even diagonally) to the same number.
Do you miss this puzzle? You better do, as this is a new game mode exclusively for Brain Age Deluxe which also contains 100 puzzles of 3 different difficulties: Beginner, Intermediate and Advanced.

Brain Tip Theatre
Dr. Blushy will tell you more about your brain as he hangs out with our dearest Numberblocks and Alphablocks. There is a quiz at the end of the theatre, so pay attention!
- One: One single red block, but also sometimes a solid "one-block". She is a cube. She resembles a cyclops, due to her one eye, unlike the other Numberblocks. She is sweet, fun-loving, curious, bubbly, friendly, and clever. Sometimes she feels self-conscious about only being a single block. She also loves finding things that there are one of. Voiced by Elizabeth "Beth" Chalmers
- Two: Two orange blocks. He wears purple glasses and two sparkling orange dancing shoes. He is very kind and smart, and is One's best friend who loves helping her make pairs, like shoes and socks. Voiced by Marcellus "Marcel" McCalla
- Four: A creature who is shaped like a number four. His most favourite subjeect is arthimetics and is a friend of Dr. Blushy. Though being the main host of Battle for BFDI makes him grumpy, he still enjoys his newfound job of being a brain trainer. Voiced by Michael Huang
- Dr. Blushy: As he is in a Nintendo Switch, he is in his Blue Shy Guy Form. In Devilish Mode, he turns into a black Shy Guy with an evil-looking mask and two horns. He is the main Brain Trainer of the game.
- Wattson: A lightbulb-shaped character which once helped Dr. Ryuta Kawashima to train other's brains.
Everything acts like Competitive Test. Results are only shown at the end of the session. As always, a Nintendo Switch Online Account is needed to enjoy this experience.
- This is the first Brain Age game which features a story.
- This is also the first time the Numberblocks and the Alphablocks appears in Asia.
- On the cover of Dr. Blushy's copy of Dr. Kawashima's Book <<Train Your Brain>>, he puts a memo paper writing "Idol No. 1" and an arrow pointing on Dr. Kawashima's name. This shows Blushy's love towards the Brain Age series.
- This is the first time a character from an online animated series got into an official Nintendo game.
- This is also the first time the Alphablocks and the Numberblocks appeared in a home console video game.
- Although this game is named Brain Age Deluxe, this game is much more similar to Body and Brain Connection in terms of gameplay. The only difference is that the players can select whether to use motion controls before the activities. (and you won't be teased if you behaved too bad.)
- The name 'Step Squad' is based on an episode of Numberblocks.
