Gain forty extra lives

From Glitches

From the arcade game Tempest.

If your score hits a certain number, then you will gain forty extra lives by a weird glitch in the system. Here is the criteria the number must meet: it is a six digit score, the first two numbers are greater than sixteen, the middle two numbers are between twenty nine and sixty, and the last two digits are zero and six, eleven, or twelve. If the last two digits are something else, all kinds of bizarre effects can happen, from the screen freezing to the game getting put into test mode.
