How to make this session variable loop when refreshing/revisiting homepage?

You could use the built-in session library, and increment/decrement the value based on its current value. Something like this:

Code:

$this->load->library('session');

if($visit = $this->session->userdata('visits'))
{
    // Handle previous visits
    if($visit < 3)
    {
        // Increment visit number
        $visit++;
    }
    else if($visit == 3)
    {
        // Reset visit number
        $visit = 1;
    }    
    // Set new visit number
    $this->session->set_userdata('visits', 1);    
}
else
{
    // First visit, initially set the value to 1
    $this->session->set_userdata('visits', 1);
}
