Method and system for arranging electronic quick lotteries

To arrange an electronic instant lottery, a plurality of electronic instant lots (510) is generated (401, 605) and stored (402, 406, 606), each of which comprises prize data which is encrypted and can be decrypted with a lot-specific key. The keys (511) with which the encrypted prize data of the stored electronic instant lots can be decrypted are stored (403, 405) separately from the stored electronic instant lots. A given player (404) is provided with access to the stored electronic instant lots such that, by paying a given fee, the player acquires a given electronic instant lot. The player is also provided with access to the stored keys such that, by presenting a proof of his possession of a given electronic instant lot, the player acquires the key corresponding to this particular electronic instant lot.
