Games implemented as stored procedures for MariaDB. You can play them from the command-line client. Can be ran on Percona Server or Oracle MySQL, but will require some small changes because I've used some MariaDB-specific features.
Each game is in a separate directory. See the README.md. in each directory for a quick explanation of the game and how to play.
To install all the games, just pass the install.sql file in the root directory to the mysql command-line client. For example:
mysql -uroot -p < install.sql
To install an individual game, run the install.sql file in the game directory as described above.
Each game will be installed in a different database, which contains the necessary routines and tables. The only routine that you need to remember is:
CALL help();
This will show you a help that explains how to play.
