Pinball game mechanic where, at the end of a game, the last two digits of the players' scores (which will always be a multiple of 10) is compared against a random two-digit number (also a multiple of 10). If a player's digits match the game's, a free game is awarded (indicated with the infamous knocker sound). The match bonus was first introduced in 1957, using the single digit of the scores; score inflation eventually elevated the match to the last two digits. Not too surprisingly, matches occur fairly infrequently. Older games had the chance of getting the free game set at around 10%, but newer games will either dynamically adjust the frequency of matches, or follow a level set by the operator, from a standard 7% to a paltry 1%. Back when pinball was a controversial subject, this feature was often banned, as it was considered a form of gambling. While it's probably not that bad, the feature is specifically designed to get more money out of players: it has a disproportionately higher chance of giving a player a match if two have just played, so the other player will deposit money and they will both play again. Older electro-mechanical pinballs used either light-up digits (for single-digit matches) or score reels (for two digits). The arrival of alphanumeric LEDs and, later, dot-matrix displays allowed match sequences to become more and more elaborate, often animated or otherwise specialized to the game's theme. Less creative machines simply show the number being generated, a practice that has all but fallen out of grace today.
