What is this ?

A game of UNO, played by bots.

4 players at the table. By default they all play cards at random.

Click a player to see the code used to select a card (javascript). Here is an example of a simple strategy:

// choose the card with highest points
return _.sortBy(playable,'points').reverse()[0];

You must return a Card, that's all you need to do.

Available variables:

• _: Underscore.js
• playable: an array of Card in your hand that are possible to play at the curren turn
• gameCard: the Card on the table at the current turn
• others: an array giving information about the other players

You can use console.log to debug your function, it will show up in your browser console.

Other examples

// group card by color, count them and order in descending order
var manyColor = _.chain(playable).groupBy('color').map(function(group){
    return {length: group.length, cards: group, color: group[0].color};
}).sortBy('length').reverse().value();

// do we have too many of a color ?
if(manyColor[0].length > 2){
  // yes we do, let's choose the best out of this color
  return _.chain(manyColor[0].cards).sortBy('points').last().value();
}

// default is to choose the point with highest points
return _.chain(playable).sortBy('points').last().value();

Why did you do that ?

That's the kind of things I do...
