A scratch card game can be played online and offline. It usually involves matching numbers or symbols. The simplest type of game would be one where you had to reveal what was underneath covered panels and match three of those the same to win the amounts that they represented.
When playing an offline game you need to scratch off the panels with a coin. This can be a bit messy and wasteful and you are limited to the types of cards available in the shop and can only purchase them at the shop opening hours. This is why many people prefer to play online. When playing an online game you wave over the panels with the mouse and this reveals what is underneath. Some of the games have themes so the symbols are all related to something so they might be cars or something like that. The basic rules are always the same – if you make the desired match you will win the specified amount of money. They are always easy to understand and play. Some people prefer the type of game where you have to reveal amounts of money and if you get three the same you win that amount.
Other people prefer games where you match pairs and if you get two the same then you win an amount of money which you also scratch off and reveal. The games do not require you to answer a question or think up a strategy, which is what makes them a lot of fun for many people. They vary in price and you can even play free scratch card games online and these give you a chance to see what they are like to play and decide if you like them or not. Most people find they are fun and love having a chance to win an amount of money whether they play online or offline.
