Когда вы инициализируете игру, просто сохраните количество попыток в вашей сессии.
$_SESSION['tries'] = 3;
Затем, когда пользователь выберет число, уменьшите количество попыток и проверьте, равно ли оно 0.
$_SESSION['tries']--;
if ($_SESSION['tries'] <= 0) {
die("Enough! You've been clicking numbers all afternoon.");
}
