    • Various aspects are directed to random number generation. A request from a game terminal for a random number may be received. Whether a new seed is required may be determined, for example, based on the time or quantity of random numbers generated since the last re-seeding. Conditioned on determining that the new seed is required, a pseudo-random number generator may re-seeded, wherein the re-seeding comprises setting a current seed value equal to the new seed. The pseudo-random number generator may generate a random number based at least in part on the current seed value; and transmit information based on the random number to the game terminal.
    • 各方面针对随机数生成。 可以接收来自游戏终端的用于随机数的请求。 是否需要新的种子可以例如基于自上次再播种后生成的随机数的时间或数量来确定。 在确定需要新种子的条件下,可以重新种子伪随机数发生器,其中重新播种包括设置等于新种子的当前种子值。 伪随机数生成器可以至少部分地基于当前种子值生成随机数; 并将该随机数的信息发送到游戏终端。
