+# game counter activity
+
+Have you ever tried to create a game counter? The concept is fairly simply: increase the game `score` with `on button pressed` .
+
+Let's start by adding `on button (A) pressed` will run each time the user presses A. Let's add a line of code that increments `score` by `1`.
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    game.addScore(1);
+});
+```
+
+
+Let's add a `add points to score` block to keep track of the current count. Since the count will change with the `add points to score` blocks, add a game block `score` to display the count on screen.
+
+
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    game.addScore(1);
+    basic.showNumber(game.score())
+});
+```

+# game counter challenges
+
+Coding challenges for the game counter. 
+
+## Before we get started
+
+Complete the following [activity](/lessons/game-counter/activity) . Your code should look like this:
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    game.addScore(1);
+    basic.showNumber(game.score())
+});
+```
+
+### Challenge 1
+
+Let's add the code to `score` when `B` is pressed. Add an event handler with `on button (B) pressed` then add the code to `score`.
+
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    game.addScore(1);
+    basic.showNumber(game.score())
+});
+
+input.onButtonPressed(Button.B, () => {
+    game.addScore(-1);
+    basic.showNumber(game.score())
+});
+```
+
+
+### Challenge 3
+
+Now let's try to reset the counter when the micro:bit is shaken. You will need to register an event handler with `on shake`.
+
