[10][11] Additionally, there is a mode that allows players to create their own levels and share them with people added to their Friend Code list via WiiConnect24.

[14] It features a physics model that ensures the blocks collapse realistically,[8] and also measures the velocity at which an object is thrown, recognising four distinct speeds.

[15][16] In the game, players use the Wii Remote to manipulate bowling balls, baseballs, laser guns, and water hoses in order to knock over structures made of blocks.

[15] Different types of blocks possess different physical properties; their mass and the amount of friction they exert alter the way they will respond to contact.

[11][16] Explore mode presents puzzle-based objectives that focus on different groups of skills,[11] allowing the player to discover the basic mechanics of the game.

The second level, Gorilda Rescue, takes place in an island jungle and involves the player helping a gorilla named Gert save her children from a tribe of hostile natives called the "Tiki".

The fourth and final world, Haunted Night, takes place on Halloween and tells the story of a family of kittens trying to get to a mansion at the end of a road; the player must defend them from enemies such as skeletons, grim reapers, and monkeys dressed as devils.

[10][18] The player can alter the size, height, and width of the blocks, clone them, and assign them attributes such as point value or type.

[20] Initially, the game was to support headtracking, the repositioning of the virtual in-game camera in relation to player's position in the room.

[22] During development, the focus was on creating a video game specifically for Wii, but senior producer Amir Rahimi has indicated that Boom Blox may be ported to other consoles in the future.

[26] Electronic Gaming Monthly out of three scores gave it an A+, an A, and an A−, stating it as "immensely accessible, wonderfully tactile, and stands as one of the best uses of 3D space."
