LED lucky wheel

Hi, I am looking to make a lucky wheel with Arduino Uno that consists of 4 LED which is activated by a button. Something similar to this: Demonstration: Arduino Lucky Wheel w/Nano, LEDs, Buzzer & 3D-Printed Wheel - YouTube

However, I am having trouble with the code.
What it does now: Starts by pushing button, takes a small break after the round is finished and then it starts a new round on itself.

If anyone have any suggestions, I would really appreciate it. Here is the current code:

// Create a global variable to hold the state of the switch. This variable is
// persistent throughout the program. Whenever you refer to switchState, you’re
// talking about the number it holds
int switchstate = 0;
int randomNumber = 0;

void setup() {
  // declare the LED pins as outputs
  Serial.begin(9600);
 
  pinMode(3, OUTPUT);
  pinMode(4, OUTPUT);
  pinMode(5, OUTPUT);
  pinMode(6, OUTPUT);


  // declare the switch pin as an input
  pinMode(7, INPUT);
}

void loop() {

  // read the value of the switch
  // digitalRead() checks to see if there is voltage on the pin or not
  switchstate = digitalRead(7);
  int myLeds[] = {3, 4, 5, 6};

  // if the button is not pressed turn on the green LED and off the red LEDs
  if (switchstate == HIGH) {

    for(int thisLed=0; thisLed<=1; thisLed++){
       delay(100);
  
      digitalWrite(3, HIGH);  // turn the red LED on pin 4 off
      delay(500);
      digitalWrite(4, HIGH);  // turn the red LED on pin 5 off
      delay(500);
      digitalWrite(5, HIGH); // turn the green LED on pin 3 off
      delay(500);
      digitalWrite(6, HIGH);  // turn the red LED on pin 4 off
      delay(500); 

   /* for(int thisLed=0; thisLed<=3; thisLed++){*/

      digitalWrite(3, LOW);  // turn the red LED on pin 4 off
      delay(500);
      digitalWrite(4, LOW);  // turn the red LED on pin 5 off
      delay(500);
      digitalWrite(5, LOW); // turn the green LED on pin 3 off
      delay(500);
      digitalWrite(6, LOW);  // turn the red LED on pin 4 off
      delay(500); 

    }

       randomNumber = random(0,3);
       digitalWrite(myLeds[randomNumber],HIGH);
       Serial.println("det randome nr er: ");
       Serial.println(randomNumber);
    
    /*delay(100);
  
    digitalWrite(3, HIGH);  // turn the red LED on pin 4 off
    delay(500);
    digitalWrite(4, HIGH);  // turn the red LED on pin 5 off
    delay(500);
    digitalWrite(5, HIGH); // turn the green LED on pin 3 off
    delay(500);
    digitalWrite(6, HIGH);  // turn the red LED on pin 4 off
    delay(500); */

   /* for(int thisLed=0; thisLed<=3; thisLed++){*/

      /* randomNumber = random(2,7);
       digitalWrite(randomNumber,HIGH);
       Serial.println("det randome nr er: ");
       Serial.println(randomNumber);*/

     
    //}
 
  
    
  }
  // this else is part of the above if() statement.
  // if the switch is not LOW (the button is pressed) turn off the green LED and
  // blink alternatively the red LEDs
  else {
    
    digitalWrite(3, LOW);  // turn the red LED on pin 4 off
    digitalWrite(4, LOW); // turn the red LED on pin 5 on
    digitalWrite(5, LOW); // turn the red LED on pin 5 on
    // wait for a quarter second before changing the light
   // delay(250);
    digitalWrite(6, LOW); // turn the red LED on pin 4 on

    // wait for a quarter second before changing the light
    //delay(250);
    
  }

   
}

How do you have the switch wired?

Do you have a pull-down resistor on pin 7?

Hi @teapot
Okay, but what then should it does?
