Use Grammar Bot to train word classes and logic. The object of the game is to collect all of the stars on the board, by programming the movement of the robot. The game can be played in two ways, either as a purely logical game where the robot is controlled by placing arrows on the board. Or where the robot is controlled by placing words from different word classes on the board. Each word class controls the robots direction of movement, where nouns, for example, can make the robot turn right and verbs to the left.
