We have been playing Ticket to Ride board game in our home for the past few weeks, the rules are fairly easy to pick up and the game play is fun while not being to serious. For those of you who enjoy Settlers of Catan or Carcassonne you will also enjoy this game. The rules are easier to understand so younger children can also play.
When you buy the game you can also register to play on the”official” website for 6 months. You get a “code” printed in your instruction manual.
You can also play for free with some limitations,like l you aren’t rated and can’t start new games, only join ones started by others. After that you have to pay or buy another Days of Wonder game. Cost is 18.00 a year and I think a good buy.
There are some sites that let you play Ticket to Ride online and for free. I have listed some of the better ones.
