-# 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())
-});
-```
