The Math Game
I built this math studying game in 2013 for my little brother, Trevor. He loved it! He's played it for hundreds of hours and solved almost 30,000 problems!

BREAKDOWN
The Math Game is built on the LAMP stack with some JavaScript for client side features.
Features
| Random Choice of Videos - reduce stimming to encourage exposure to a variety of videos while also maintaining choice. |
| Sandboxing - reward videos auto-play with no controls and auto-return to the problem page when the video's done playing. |
| Detailed Statistics - number of problems solved, usage over time, time spent on work vs. reward, and more! |
Database
User management is done with UserCake 2.0.2 (discontinued since 2017).
Notable game tables in the schema are:
| problems - preset problems & answers |
| settings(user_id) - operators' input ranges, # of problems to solve |
| videos - youtube video id, meta info to display it |
| game_state(user_id) - current problem, # of problems remaining |
| rewards(user_id) - video watched, # of problems solved, timestamp |
| results(user_id) - problem, how long it took, timestamp |
Setup
- Set up a MySQL database with the schema in setup/mathgame.sql.
- Pre-populate the database with a fixed set of problems (source):
<?php
populateProblems(
populateOperators(array(
'+' => 'addition',
'-' => 'subtraction',
'*' => 'multiplication',
'/' => 'division'
)),
0, // minimum input value
99 // maximum input value
);
?>
