If you're using one of the saves then it wont pop because ive already unlocked it. If not, best do it in infinity mode or on one of the tales. Clear the board down to the last layer and then just speed through the last 5 matches.
no ive not used the save yet as i knew it wouldnt unlock, im trying to do as much myself before using it.
ive tried all sorts, leaving the last 5 pairs and working out a way to get it fast, but it still wont pop.
its glitchy anyway i know some people have finished the first tale and not got the trophy or the one for not using hints, this is over on ps3t.org so its a glitchy sort of game.
