Computational thinking helps to break down complex issues leading to solutions, learning this skill is essential to navigate in digital world. Learning through games is one strategy used in the past. This strategy is used in this board game (Branch Master) to explain binary search tree (BST) based searching and insertion operations. A strong connection between content and gameplay is created by employing an endogenous design based on BST operations to promote computational thinking in a social context. The game is built considering players know how to compare two numbers with minimalistic rules. The game has an inherent challenge due to conflict and competition which will make players engage throughout the game play.
