Angels & Demons

Angels & Demons is a mobile game based on the novel by Dan Brown and its subsequent 2009 movie adaptation. The game takes place in and around Vatican City as symbologist Robert Langdon attempts to stop the murders of Catholic cardinals while progressing through levels of increasingly challenging puzzles.

Gameplay is based on a puzzle game known as marble solitaire in which the player must clear rows of marbles by jumping a marble from one end to the other, and continuously removing marbles until only one or a few remain. This mobile game introduces a scoring system in which the player receives a higher score for removing multiple marbles with one jump, and elemental marbles which grant bonus points when like marbles are removed together. There is also a level type in which the player must end the level with the final marbles in a specific tile.
