+## Extending the Extension
+
+One effect of the extension is the **X** for a false start shows for the person loosing the game. We can extend the code some more to avoid the **X** showing up on the person loosing the game. The following example uses a new variable to flag the winner and avoid the **X** after a winner is crowned.
+
+```blocks
+input.onPinPressed(TouchPin.P0, function () {
+    running = false
+    false_start = false
+    Winner = 0
+    basic.showNumber(3)
+    basic.showNumber(2)
+    basic.showNumber(1)
+    basic.clearScreen()
+    basic.pause(1000 + randint(0, 2000))
+    if (!(false_start)) {
+        start = input.runningTime()
+        running = true
+        led.stopAnimation()
+        basic.clearScreen()
+        led.plotBrightness(randint(0, 4), randint(0, 4), 255)
+    }
+})
+input.onPinPressed(TouchPin.P2, function () {
+    if (running) {
+        running = false
+        end = input.runningTime()
+        Winner = 2
+        basic.showLeds(`
+            . . . # #
+            . . . # #

+            . . . # #

+            `)
+        basic.pause(1000)
