Why does this golang program hang in playground when using for loop with select?

Consider this playground

    messages := make(chan int, 1)
    done := make(chan bool)
    go func() {
        for {
        select {
            case msg := <- messages:
                fmt.Println("receiver one", msg)
            case signal := <-done :
                fmt.Println(signal)
                return
            default:
                fmt.Println("no message received")
        } 
        }
    }()
    go func() {
        for {
        select {
            case msg := <- messages:
                fmt.Println("receiver two", msg)
            case signal := <-done :
                fmt.Println(signal)
                return
            default:
                fmt.Println("no message received")
        } 
        }
    }()
    go func() {
       for i := 0; i < 2; i++ {
           messages<-i
       }
       done<-true
       done<-true
       done<-true
    }()

    <-done

I am trying to simulate communicate from one thread to two other thread, but it seems like the above code is running fine in my local but not in playground.

Is there a trick to make the program work?

You should remove the default clauses from the select statements.

Since your select statement is within a for loop and the default clause prevents it from blocking, the loop has to go through a lot of cycles before any message will be received.

Looks like Playground detects it and stops the program.

As @dev.bmax already mentioned, you use default in a wrong way.
Check this small article about using default keyword.

Also, try to add runtime.GOMAXPROCS(4) on the beginning of your program, run few times and check output to see, how it's working:

Here's correct example for you:

Note, that in this case you should use different channels for stopping additional and main goroutines.
