 # flipperzero-pong
 A Pong game for the Flipper Zero
+
+![](https://github.com/nmrr/flipperzero-pong/blob/main/img/Flipper_Zero.jpg)
+
+Assuming the toolchain is already installed, copy **flipper_pong** directory to **applications_user**
+
+Plug your **Flipper Zero** and build the Pong :
+```
+./fbt DEBUG=no LIB_DEBUG=no COMPACT=yes launch_app APPSRC=applications_user/flipper_pong
+```
+
+The game will automatically be launched after compilation
+
+Because of the position of control pad on the **Flipper Zero**, this Pong has been programmed to be played in vertical position
+
+Press **Up** or **Down** to move your paddle. Press back button to quit
+
+If you don't want to build the game, just simply copy **flipper_pong.fap** on your **Flipper Zero**
