Noneho uhuze imirongo itatu, kubwibi urashobora gukoresha PIN yicyongereza. Ibibanza biva mumirongo yumuringa. Niba imwe mumatsinda iba mugufi, andika umurongo ukurikira kuri yo. Nibyiza kudoda imirongo murwego rwa chess kugirango twirinde ingingo zabo. Ingurube ya CM ya nyuma igomba guruma igitambaro kugirango igere kumpera. Kubwibyo, ubugari bwibanze bwa patchwork bugomba kugabanya buhoro buhoro ubugari bwayo, hafi kabiri ubunini bwambere. Iyo ingurube yiteguye, ifatanye. Ukoresheje urushinge ninsanganyamatsiko ziramba, kudoda umugozi wambere wingurube. Kuzunguruka umurongo w'ingurube ku kaga, wambukira ingurube hagati. Ufite rero uruziga cyangwa oval.
