Magic cube, or the Rubik’s cube, is a popular 3D puzzle known by almost everyone in the world. There was a time when a lot of classmates in our class (including me) were crazy about this game. Everyone was trying to remember the awkward patterns and formulae for not only figuring out this puzzle but beating each others time records. Being very fond of designing games using Visual Basic and inspired by this puzzle, I constructed this simulated program for playing the magic cube.

A player can enter in commands on the input field according to the description (e.g. k = turn right face 90° clockwise, a = Reset cube …) in order to control the cube. The program would only show the front, right and top side of the cube, so the player should have to rotate the whole cube using certain commands for observing every side. Although it is more difficult to solve a scrambled cube for a normal human using this program, it is still possible if one takes time :). Lots of geometric concepts were used when designing this program. For instance, how should the data structure look like in order to record every block of color on the 6 sides of the cube? How can the variables be permutated if a certain command (e.g. turn top face 90° counter clockwise) is executed? How to even draw the cubes diagonal view?

I learned a lot myself from creating this program, gaining insights into various seemingly simple but somewhat counter intuitive geometric and algorithmic concepts.

This project is the first of the three “Guess the Number” projects that I’ve completed (before Guess the Number (iOS) and Guess the Number AI). I had played this game long before I wrote this program. During the period when I was self-learning Visual Basic, I decided to make a program of this game which the player guesses the number randomly generated by the program.

The two-player game is also named Bulls and Cows, which one player thinks of a four-digit number with every digit being unique and the other player trying to guess that number. During each turn, the player who guesses speaks a number while the other replies with how many A’s and B’s according to the relationship between the guessed number and answer. The number of A’s indicate how many digits in the guessed number are identical with those in the answer and are on the same location; the number of B’s indicate how many digits are identical but aren’t on the same location (e.g. 2A1B should be replied when a guessed number is 1234 and the answer is 1532). The player guesses until the answer is guessed and the round ends. Players may take turn playing the opposite role and try to guess as few times as possible.

This mini-project encouraged me to design more complex programs, and is an important milestone in my journey of programming.

Once upon a time, when cell phone screens were only black and white…

This game “racecar” had been the most interesting one on my first Motorola cell phone. Learning Visual Basic on my own, I had tried to mimic and construct games that I’d played before, hoping one day I could make up some fantastic ones of my own. Racecar is a simple successive one at the initial stages of my self-learning of programming.

The player first picks a game level from 1 to 9, game starts after the countdown of 3 and three adjacent blue squares representing a racecar travels down a track where obstacles will be encountered frequently. The player can move left or right in order to dodge the obstacles, and the longer he survives, the more points he will get.

This project is the first game for me to implement programmable drawn shapes as the objects, and led me into the discovery of the important fundamentals of program logic.
