In Doodle Jump, the aim is to guide a four legged animal called "The Doodler" up a never-ending series of platforms without falling. The left side of the playing field is connected with the right side. For devices with an accelerometer, players tilt the device from side to side to move the Doodler in the desired direction. Players can get a short boost from various objects, such as propeller hats, jetpacks, rockets, springs, trampolines and invulnerability shields (some levels only). There are also monsters and UFOs that the Doodler must avoid, shoot, or jump on to eliminate. Aiming is performed by tapping on different parts of the screen, on the Android and Windows Phone versions of the game there is also an automatic aim mode. Depending on the game mode being played, projectiles may fly in a straight line off the screen or be affected by gravity and fall downwards. There is no definitive end to the game, but the end for each gameplay session happens when the player falls to the bottom of the screen, jumps into a monster, gets sucked into a black hole, or is abducted by a UFO. Players can choose from several different themes including Original, Christmas, Halloween, Rainforest, Space, Soccer World Cup, Underwater, Easter, Ice Blizzard, Ninja or Pirate.
