Scratch cards are small cards that have a concealed area covered by a thin layer of opaque material. Players use a coin or their fingernail to scratch off this layer, revealing symbols or numbers underneath. If the revealed symbols match a winning combination, the player can claim a prize, which can range from small amounts to larger jackpots. These cards are often sold by lottery organizations and are popular for their simplicity and instant gratification. They come in various themes and price points, making them accessible to a wide audience. Scratch cards are a form of gambling and are regulated in many regions to ensure fairness and legality.
