I think the first check you want to check if the offset is NOT set:

<?php

if (! isset($_SESSION['word'])) {// Note the ! operator
}

Hi Yoel

Your almost there on your attempt, you want to check if the session variables are not set then redirect to play.php else set the p parameter with the variables

<?php
session_start();

for ($i = 1; $i <= 5; $i++) {
  if ( empty( $_SESSION['word'][$i] ) ) {
    if ( $i ) {
      header('location:play.php?p=' . $i);
      exit;

    } else {
      header('location:play.php');
      exit;
    }
  }
}
$word1 = htmlspecialchars($_SESSION['word'][1]);
$word2 = htmlspecialchars($_SESSION['word'][2]);
$word3 = htmlspecialchars($_SESSION['word'][3]);
$word4 = htmlspecialchars($_SESSION['word'][4]);
$word5 = htmlspecialchars($_SESSION['word'][5]);

include 'inc/header.php';

echo '<h1>My Treehouse Story</h1>';

echo '<p>There once was a(n) ' . $word1;
echo ' programmer named ' . $word2; 
echo '. </p>';
echo '<p>This ' .  $word3; 
echo ' programmer used Treehouse to learn to ' . $word4;
echo ' the ' . $word5 . '.</p>';

echo ' <a class="btn btn-default btn-lg" href="#" role="button">Save Story</a>';
echo ' <a class="btn btn-default btn-lg" href="play.php" role="button">Play Again</a>';
echo ' <a class="btn btn-default btn-lg" href="index.php" role="button">Other Stories</a>';


include 'inc/footer.php';

Good Luck
