# rock paper scissors challenges Coding challenges for the rock paper scissors tutorial. #docs ## Before we get started Complete the following [guided activity](/microbit/lessons/rock-paper-scissors/activity) , your code should look like this: ``` input.onGesture(Gesture.Shake, () => { let img = images.createImage(` . . . . . # # # # # . . . . # . # # # . # . . . # # # . # . . # # # . # . . . # . . # . . . # # # . # . . . # # # . # . . . . . . # # # # # . . . . # `) img.plotFrame(Math.random(3)) }) ``` ### Challenge 1 When the `A` button is pressed, increment the **score** by ``1``. You can use the `game->add score` function for that. ``` input.onGesture(Gesture.Shake, () => { let img1 = images.createImage(` . . . . . # # # # # . . . . # . # # # . # . . . # # # . # . . # # # . # . . . # . . # . . . # # # . # . . . # # # . # . . . . . . # # # # # . . . . # `) img1.plotFrame(Math.random(3)) }) input.onButtonPressed(Button.A, () => { game.addScore(1) // *** }) // *** ``` ### Challenge 2 After incrementing the score, display the total number of wins you have. ``` input.onGesture(Gesture.Shake, () => { let img2 = images.createImage(` . . . . . # # # # # . . . . # . # # # . # . . . # # # . # . . # # # . # . . . # . . # . . . # # # . # . . . # # # . # . . . . . . # # # # # . . . . # `) img2.plotFrame(Math.random(3)) }) input.onButtonPressed(Button.A, () => { game.addScore(1) basic.showString("WINS: ", 150) // *** basic.showNumber(game.score(), 150) // *** }) ``` * Run and compile the code to see if it works as expected. ### Challenge 3 You have successfully tracked and displayed the number of wins on the BBC micro:bit! However, what about losses? Use `game->remove life` when button `B` is pressed. * Run and compile the code to see if it works as expected.
