A scratchcard (also known as a scratch off, scratch ticket, scratcher, scratchie, scritchies, scratch-it, scratch game, scratch-and-win, instant game or instant lottery in various places) is a little card, often manufactured from thin paper-based card for competitions and plastic to conceal PINs, where a number of areas contain concealed info which may be revealed by scratching off an opaque covering.

Applications include cards sold for gambling (especially lottery games and quizzes), free-of-charge cards for quizzes, fraudulent free cards encouraging calls to premium rate phone services, also to conceal confidential details such as for example PINs for telephone phone cards (otherwise referred to as recharge cards) and other prepaid services.
In some cases the complete scratchable area must be scratched to see whether a prize has been won-the card is printed either to become a winner or not-or to reveal the trick code; the result will not rely upon what portions are scratched off. In other cases, some however, not all areas need to be scratched; this might apply in a quiz, where in fact the region corresponding to the proper answer is usually scratched, or in a few gambling applications where, based on which areas are scratched, the card wins or loses. In such cases the card becomes invalid if way too many areas are scratched. After losing you can scratch every area to observe if, how, and what you can have won with this card.
Technology
The scratchcard itself is made from paper-based card, or plastic, with hidden information such as for example PIN or HRN (Hidden Recharge Number) printed onto it, included in an opaque substance (usually latex). The initial cards were covered with an environmentally unsafe solvent based coating. In the late 1980s, adhesive specialist Jerome Greenfield invented a safe water-based coating still found in scratchers today which can be scratched off relatively very easily, while resistant on track abrasion. Other styles of scratch panel are scratch labels, hot stamp foil or 'sandwich' label which are technologies that's easy to create for manufacturers without specialised equipment for applying latex panels. Unlike silkscreen latex panels that bond with the card body, labels are distinctly separate to the card body and applied by adhesion making them susceptible to sophisticated and fraudulent manipulation.

Origins
The initial game tickets were produced using manual randomization techniques. In 1974 the American company Scientific Games Corporation led by scientist John Koza and retail promotions specialist Daniel Bower produced the first computer-generated instant lottery game. In 1987, Astro-Med, Inc. of West Warwick, Rhode Island, received the U.S. Patent for the moment scratch-off lottery ticket
Simple prize scratchcards require the player, for instance, to scratch off three (or even more) areas hiding numbers, symbols, etc. If every item revealed will be the same, a prize offers been won. More difficult scratchcards have a number of different ways to win using one card. Additional scratchcards involve matching symbols, pictures or words, or are adaptations of popular (card-)games such as for example blackjack, poker or Monopoly. Games are also linked with popular themes such as for example Harley Davidson, Major League Baseball, NASCAR, the National Hockey League, Marvel Comics and FIFA World Cup.
There are two major manufacturers of game tickets: Scientific Games Corporation, with production facilities in america, Chile, UK, Germany, Canada, Brazil and Australia; and Pollard Banknote, with production facilities in america and Canada. There are many other smaller manufacturers in THE UNITED STATES, Europe, and Asia.
Popularity
Scratchcards are an extremely popular type of gambling because of their low priced and the chance to win instantly, instead of looking forward to a drawing like many lotteries. There exists a trend towards more costly scratchcards (20-50 USD) which have prizes in the huge amount of money. However, many such "instant" tickets sold in america, especially in Massachusetts and NY, usually do not pay top prizes "instantly," but instead over many years, without cash option.
The popularity of lottery scratchcards has been increasing at a larger rate than any other type of lottery.
Predictability
In the 21st century there were attempts to increase the chances on finding a prize-winning card predicated on statistics, by tracking the quantity of prize money won and cards sold to calculate accurate current odds. There were numerous instances where a group of cards remain available although all major prizes have already been won. Some lotteries get this to information open to all cost-free to greatly help promote their games Hypothetically, large early payouts may exceed ultimate sales before expiration of the overall game card series. However, the reduced probability of winning - typically from significantly less than 1 in 5 to about 1 in 2.5 - and players who buy cards unacquainted with the reduced return offset these losses, therefore the lottery still makes a profit.
