Pure memorization of English words are usually uninteresting and provides limited help to the improvement of English proficiency. This paper imitates the popular block elimination puzzle game of Candy Crush Saga to develop a similar mobile game about English vocabulary elimination. The proposed puzzle game in this paper is used as an integrated tool with an e-book reading system and is utilized for vocabulary practices and examinations. The design and implementation of the proposed tablet-based mobile game aims to make English vocabulary learning more interesting and motivated. The purpose is to provide a game-based tool for English as a Second Language (ESL) learners to improve their English learning efficiency.
