Gambling Legend

Gambling Legend is a platform to bet on random URF matches created for the Riot Games API challenge. Every 10 minutes a random URF match is chosen and all active bets are evaluated. The odds for the different choices are calculated by their rate of appearance. Thus you need a basic set of matches to have interesting odds.

You can try all the features as a guest without signing up. It will work the same as an original user except for the session being deleted when you close the browser. To save your winnings you need to sign up.

Demo

A demo version of the submitted API challenge entry can be found here: https://gambling-legend.herokuapp.com/

Preconditions

For Ubuntu/Debian

• Ruby 2: https://rvm.io/rvm/install
• bundler: sudo gem install bundler
• sudo apt-get install postgresql postgresql-client libpq-dev
• Setup a databse user: https://wiki.debian.org/PostgreSql
• Node.js (optional)

Setup

git clone git@github.com:AmShaegar13/gambling_legend.git
cd gambling_legend

If you don't have node.js you will need to uncomment therubyracer in Gemfile. Make sure you are not running Ruby 1.9 (ruby -v). Use Ruby 2, eg. rvm use ruby-2.2.2

bundle install

Open config/database.yml and setup your postgresql connection.

export PSQL_PASSWORD=yourpassword
export RIOT_API_KEY=...-...-...-...
rake db:setup

Start the server on port 3000:

rails s -p 3000

You are now running the full application in development mode. To start in production you will need to set RAILS_ENV=production and precompile assets first.

Operation

The Rails environment includes a worker that runs in its own thread and evaluates the bets every 10 minutes. Alternatively, you can start a daemon with ruby daemon/bets.rb start or trigger the evaluation once manually by running rake cron:bets.
