Hardware Enginnering is a simplified digital circuit design game presenting an opportunity to dive into digital engineering with ease. The game goes from the basic logic components to those of a great complexity, so that the expertise of player who has gone through the whole game is comparable with first college levels, and yet the game requires no previous knowledge of electronic design or programming. Every new theoretical idea is first presented to you in a tutorial and subsequently practised in the near workspace. The outputs of your design efforts are tested through a list of tasks, so that there are practically infinitely-many ways to reach the next level, although some are more optimized than others. However, the more ingenuous designs begin to be an absolute necessity when you move further in the game. There are four game modes featured. Slow-paced Tutorial and Design modes allow you to design each component they further use from the basic logic. A set of 25 (+hidden) achievements then makes your progress visible to
