In Doodle Jump, the aim is to guide a four-legged creature called a doodler (named doodle) up an never-ending series of platforms without falling. 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 or trampolines. There are also monsters and UFOs that the Doodler has to shoot or jump on to eliminate. Aiming is performed by tapping on different parts of the screen. 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 eventually. There is no definitive end to the game, but the end for each gameplay happens when the players falls (by reaching the bottom of the screen), jumps into a monsters, gets sucked into a black hole, or is abducted by a UFO. The newest updated version of the game lets players choose between versions of the game (Classic, Christmas, Rainforest, Space, Soccer World Cup, Easter, Underwater, Ice Blizzard, or Halloween) without changing their names. After losing the game at least 500 times (600 in the BlackBerry version) the Doodler is given the opportunity to wear a pickle costume. Alternatively, the player may enter the names of one of the Pocket God pygmies as a name as the Doodler will become one.
