This is one of the most popolar games for arduino .You can find other versions on Internet but this versions only cntain one button ,the jump button .This version i find it on Arduino Projects Hub but it are made for a 12C conection display ,I adapt myself the code for a normal display.

Supplies

Arduino UNO R3.
LCD screen 16*2.
10K potenciometer.
3 push buttons.
3 10K resistors.
Piezo Buzzer.
Some jumper wires.

Step 1: The Shematic:

The shematic is simple to make .YYou just need to conect thewwires and components like the image .It's simple.but...pay attention on the wiring because it simple at the limit ,this wiring can make a lot of mess,so ,pay attention what are you doing ,yes?ok.Let's program the arduino...

Step 2: The Code:

Put this code into the Arduino IDE or Arduino Web editor.
