How to enable a start button after clicking stop buttons

I want to enable my start button after clicking all the three stop buttons.

I tried to place the button

btn4.enabled = false
inside the (
sender == btn3
), but the start button will be enabled if I first clicked on that button.

The three stop buttons can be clicked in random order.

Here's my code so far:

namespace SlotMachine
{
class SlotMac
{
private Form f;
Button btn1 = new Button(); // First stop
Button btn2 = new Button(); // Second stop
Button btn3 = new Button(); // Third stop
Button btn4 = new Button(); // Start
Timer Clock; // Tick
Timer Clock1; // Tick
Timer Clock2; // Tick
Int32 tick = 0;
Label tb = new Label();
int[] nNum = new int[3];

public SlotMac()
{
f = new Form();
f.Text = "Slot Machine";
//f.Size = new Size(800, 700);
f.FormBorderStyle = FormBorderStyle.FixedSingle;
}

PictureBox[] pics = new PictureBox[7];
PictureBox[] pics1 = new PictureBox[7];
PictureBox[] pics2 = new PictureBox[7];
//PictureBox pb = new PictureBox();

public void Launch()
{
Random r = new Random();
int i = 0;
//int x = 0;
//int x = 50;

tb.Location = new Point(205,20);
f.Controls.Add(tb);

Clock = new Timer();
Clock.Interval = 800;
Clock.Tick += new EventHandler(Clock_Tick);

Clock1 = new Timer();
Clock1.Interval = 800;
Clock1.Tick += new EventHandler(Clock1_Tick);

Clock2 = new Timer();
Clock2.Interval = 800;
Clock2.Tick += new EventHandler(Clock2_Tick);

for (i = 0; i < pics.Length; i++)
{
pics[i] = new PictureBox();
pics[0].Image = Image.FromFile(i + ".jpg");
pics[i].SetBounds(50, 100, 100, 100);
//x += 150;
f.Controls.Add(pics[i]);
}

for (i = 0; i < pics1.Length; i++)
{
pics1[i] = new PictureBox();
pics1[i].Image = Image.FromFile(i + ".jpg");
pics1[i].SetBounds(200, 100, 100, 100);
//x += 50;
f.Controls.Add(pics1[i]);
}

for (i = 0; i < pics2.Length; i++)
{
pics2[i] = new PictureBox();
pics2[i].Image = Image.FromFile(i + ".jpg");
pics2[i].SetBounds(350, 100, 100, 100);
//x += 50;
f.Controls.Add(pics2[i]);
}

f.SetBounds(10, 20, 500, 500);

// STOP
btn1.Location = new Point(50, 250);
btn1.Height = 40;
btn1.Width = 100;
f.Controls.Add(btn1);
btn1.Text = "STOP";
this.btn1.Click += new EventHandler(this.MyButtonClick);

// STOP
btn2.Location = new Point(200, 250);
btn2.Height = 40;
btn2.Width = 100;
btn2.Text = "STOP";
f.Controls.Add(btn2);
this.btn2.Click += new EventHandler(this.MyButtonClick);

// STOP
btn3.Location = new Point(350, 250);
btn3.Height = 40;
btn3.Width = 100;
btn3.Text = "STOP";
f.Controls.Add(btn3);
this.btn3.Click += new EventHandler(this.MyButtonClick);

// START
btn4.Location = new Point(200, 370);
btn4.Height = 40;
btn4.Width = 100;
btn4.Text = "START";
f.Controls.Add(btn4);
this.btn4.Click += new EventHandler(btn4_Click);
f.ShowDialog();
}

}
}

public void MyButtonClick(object sender, EventArgs e)
{
if (sender == btn1)
{
Clock.Stop();
}

if (sender == btn2)
{
Clock1.Stop();
}

if (sender == btn3)
{
Clock2.Stop();
}
Finish();
}

public void btn4_Click(object sender, EventArgs e)
{
Clock.Start();
Clock1.Start();
Clock2.Start();
btn4.Enabled = false;
}

public void Finish()
{
if (nNum[0] == nNum[1] && nNum[0] == nNum[2])
{
this.tb.Text = "Congratulations!";
}
}
}
}

Answer

You can check if all timers already stopped, like this:

public void MyButtonClick(object sender, EventArgs e)
{

    if (sender == btn1)
    {
        Clock.Stop();
    }

    if (sender == btn2)
    {
        Clock1.Stop();
    }

    if (sender == btn3)
    {
        Clock2.Stop();
    }
    Finish();

    if(!Clock.Enabled && !Clock1.Enabled && !Clock2.Enabled)
       btn4.Enabled = true;
}
