Abstract: Embodiments are directed towards providing video game gameplay incorporating falling puzzle mechanics influenced by character movements within a puzzle space. In a preferred embodiment, a computer implemented method renders a game world that includes a puzzle space wherein a sequence of falling items aggregate in a puzzle formation. Players move characters within the puzzle space to remove items by colliding with them in an attempt to resolve the puzzle by clearing all items from the puzzle space. In one possible arrangement, the sequence of falling items is released according to character movements within the puzzle space. The relationship between character movements and falling puzzle items makes the game play more engaging by providing additional strategic and competitive elements to traditional falling puzzle games.
