Table 2.

“Gameplay Bricks” model (Djaouti et al., 2008).

Bricks “Play”		Bricks “Game”
Representing the means This brick invites the user to…		Representing the goals This brick invites the user to…
SHOOT	Hit one or more distant targets	AVOID	Avoid elements, obstacles, enemies or opponents
MANAGE	Manage resources to reach precise objectives	DESTROY	Destroy elements or enemies
MOVE	Drive/lead/take the control of an element or a character	MATCH	Maintain one or more elements in a place, or maintain a defined equilibrium status
RANDOMIZE	Generate a random value	CREATE	Assemble, build, create elements, color, draw from patterns, or predefined brushes; it appeals to the creativity of the user
WRITE	Enter an alphanumeric string as a response, or trigger a game function
SELECT	Select an item on the screen

On the top left, the six “bricks play” (means); on the top right, the four “bricks game” (goals); Each metabrick (gameplay challenge) derived from the combination of one play brick (mean) and one game brick (goal). Hence, it exists 24 metabricks, which reflect 24 possible game challenges.
