The latter is a mix of music, food and pop culture.
Different approaches are used to answer the questions.
Players can tap to fill in the missing letters in words, cross letters out, select the correct answer from a list of possibilities (through words or images), do pairs matching by drawing lines, or use the stylus to arrange a sequence in the correct order.
Questions appear in the upper screen and answers need to be inputted in the lower part.
There are many cartoony characters and backdrops that provide a visual element to the questions.
Questions are organized in series and the game keeps track of the player's score.
The available game modes are Brain Mode, Quest Mode, Multiplayer, and Sudoku.
Collectibles can be gathered while playing and these are stored in a separate menu.
In Quest Mode players participate in the Quest Extreme Games festival and complete quizzes to talk to other kids, win competitions and research subjects.
Prizes awarded in this mode are used in a customizable scrapbook.
Multiplayer is of the hot seat variety where the DS is passed on and scores are compared afterwards.
Multiplayer can also be done cooperatively.
The Sudoku mode offers sudoku puzzles of 4x4, 6x6, and 9x9.
The game mechanics are identical to Brain Quest: Grades 3 & 4 , released on the same day, only the content is different.
About Nintendo DS
The dual-screen, touch-enabled Nintendo DS (2004) became the best-selling handheld of all time, helped by its huge and genre-diverse library. Cartridge-based DS games have held up well physically over 20 years, and complete-in-box copies of the system's biggest sellers (Nintendogs, Pokémon, Mario Kart) remain very accessible for new collectors starting out.
Gamevaro tracks Brain Quest: Grades 5 & 6 for Nintendo DS with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Brain Quest: Grades 5 & 6 to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This NDS release dates back to 2008.

Market insights
Rarity & condition
Brain Quest: Grades 5 & 6 has a steady sales history on the tracked marketplaces, meaning enough copies circulate to establish a reliable market price.
