Additional Exciting Snap! Programs

This is a collection of tutorials: most of which describe the design of interesting and challenging Snap programs. Some articles also address advanced topics about how to do something in Snap.

Library: Here, we list several commonly used controls and procedures, which can be imported by any Snap program. We have used some of these controls and custom blocks in subsequent projects.

Show string: This short program takes a word (string of alphabets) and simply displays it in a graphical format.

Scramble: This is a two-player game in which Player1 enters a word. The program then scrambles it up, and Player2 needs to rearrange the letters to unscramble the word.

Number table: Several programs require the display of numbers in a table format, i.e. in rows and columns. This program allows you to create a square table big enough to display natural numbers (i.e. > 0) up to a max that you specify. For example, if you specify the max as 75, the program will show a table with 9 rows and 9 columns, and display numbers 1 to 75 in this table.

Base converter: This program allows you to convert numbers from one base to another. We will allow bases 2 (binary), 8 (octal), 10 (decimal), and 16 (hexadecimal). It is a kind of educational tool to further our understanding of these number systems.

Snakes and ladders: This is a popular game in which players traverse a series of numbers 1 thru 100 and work through snakes and ladders along the way. You get to play with the computer!
