Arruino Uno Crystal Ball

Hello I was working on the crystal ball project and I got it working on a breadboard and I switched it over to a prototype board. It powers up and displays the initial text but the tilt switch has no effect on the display when activated. Any clues as to where I can start troubleshooting? I followed my layout from the breadboard.

Unfortunately I don't have a crystal ball, so without you enlightening us no clue.

Do let me know where you got your crystal ball! This as with all those forum newcomers who simply ignore or otherwise fail to read the sticky (you're not the only one today), it'd come in terribly useful.

The clouds are clearing , I think I can see a wrongly wired tilt switch that ( I think it’s digital), doesn’t have a pull up resistor plus an undefined digital input ..
( tea leaves are not so sure and recommend a view of the code and circuit diagram)

Unfortunately I don't have a crystal ball...

You don't?...
Put one on your Christmas wish list.
Crystal balls are an essential tool for forum members that are answering post from newbies.

I know! That's why I immediately clicked on this post when I saw the headline. Arduino crystal ball, sounds awesome, but unfortunately I need one in the first place...

It's been on my wish list for a while but doesn't seem to come true. I wonder if they really exist.

 This example code is part of the public domain

// include the library code:
#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

// set up a constant for the tilt switchPin
const int switchPin = 6;

// variable to hold the value of the switchPin
int switchState = 0;

// variable to hold previous value of the switchpin
int prevSwitchState = 0;

// a variable to choose which reply from the crystal ball
int reply;

void setup() {
  // set up the number of columns and rows on the LCD
  lcd.begin(16, 2);

  // set up the switch pin as an input
  pinMode(switchPin, INPUT);

  // Print a message to the LCD.
  lcd.print("Ask the");
  // set the cursor to column 0, line 1
  // line 1 is the second row, since counting begins with 0
  lcd.setCursor(0, 1);
  // print to the second line
  lcd.print("Crystal Ball!");

void loop() {
  // check the status of the switch
  switchState = digitalRead(switchPin);

  // compare the switchState to its previous state
  if (switchState != prevSwitchState) {
    // if the state has changed from HIGH to LOW
    // you know that the ball has been tilted from
    // one direction to the other
    if (switchState == LOW) {
      // randomly chose a reply
      reply = random(8);
      // clean up the screen before printing a new reply
      // set the cursor to column 0, line 0
      lcd.setCursor(0, 0);
      // print some text
      lcd.print("the ball says:");
      // move the cursor to the second line
      lcd.setCursor(0, 1);

      // choose a saying to print baed on the value in reply
      switch (reply) {
        case 0:

        case 1:
          lcd.print("Most likely");

        case 2:

        case 3:
          lcd.print("Outlook good");

        case 4:

        case 5:
          lcd.print("Ask again");

        case 6:

        case 7:
  // save the current switch state as the last state
  prevSwitchState = switchState;

Do you have a circuit diagram, so you can at least verify that your wiring is correct? That's most likely the issue, especially if you try and build something based on spaghetti.
