Gems to be used in the draws for a draw day, including the interior of the blowing chamber and the blowing mechanisms. This is to make sure there is nothing hidden in the Mega Gems that will invalidate the entire draw, such as hidden balls or obstructions. The Mega Gems are also given a dry run using a set of unmarked ping-pong balls to test if they would work as they should come to the actual draw. The balls to be used in each game are stored inside briefcases. There are usually three cases of balls to be used on each game, distinguished by either numbers or uppercase or lowercase letters. The panel randomly chooses one set using cards and its chosen card is shown. In the lot games such as the Super Lotto 6/49 and 2D Lotto, the balls are of one colour, and each set may have a different colour. In the digit games such as the 6D Lotto, no matter the set is chosen, each digit from 0 to 9 has a different colour, and each set is identical. In Small Town Lottery games, all balls are of one colour. After one set of balls has been chosen for a game, each of the balls is weighed to see if they have the same or almost the same weight using a digital scale. This part of the procedure is covered by a separate video camera, which will record any abnormal circumstance, such as ball switching or a ball which either is overweight or is too light, should it comes out. After the balls for the game are weighed, they are loaded by hand by the head of the panel into the loading bays of the game's Mega Gem. This is the only first of the two times human intervention is needed as each Mega Gem is operated using a remote console stationed a small distance away from the unit. The second, never shown but implied, is the removal of the balls from the Mega Gem after each draw show has ended and the results of the draws are recorded. In the case of digit lottery games, the removal of balls is the third time, as the drawn balls are also adjusted (see below). Each Mega Gem, depending on the type of game, as already mentioned, is operated by automation. The Mega Gem loads the balls from the
