* 当有一或多个牌手全押时，德州扑克的彩池分配较为复杂，超过牌手押注金额的部份将会形成一或多个边池。
* 牌手参与投注该彩池才有机会于该彩池胜出分配奖金。
*
* 当一局结束而且有“全押”的牌手赢牌时，该牌手有参与投注的主池边池奖金均归该牌手。
* 而其他边池由参与该边池投注里，持有最大牌面的牌手赢得。
* 在几个牌手全押形成多个边池时，依全押的顺序分配给各边池中最佳牌面的牌手。
* 无人跟注的边池（仅有一位牌手下注，剩下其他牌手都盖牌）将会直接赢得该边池。
*
* 彩池分配范例：
*
* 例如ABCDEF六名牌手参与牌局，F于中途盖牌退出，最终A全押投入$50，B全押投入$250，C全押投入$350，
* DE各投入$800，F投入$500，此时总彩池大小为$2750，形成了一个主池为50*6=$300，
* 边池各为（250-50）*5=$1000，（350-250）*4=$400，（500-350）*3=$450，（800-500）*2=$600，
* 若最终组成牌面大小为F>A>B>D>E>C，但F已盖牌不能分配任何彩池，则此局主池即为A于此局赢得的筹码（$300），
* B可赢得第一个边池（$1000），D参与至最后一个边池，且牌面胜过参与第二、第三及第四边池的所有牌手，
* 因此可赢得剩下所有的边池（400+450+600=$1450）。
