ni no kuni casino trick. Tombstone Trail Casino is opened on the Tombstone Trail after learning the Travel spell. This gains you access to the RIP theater room and unlocks. You're a gambler gorgeousgamer, you should seek help for your 'passive' gambling addiction:) I EMBRACE it!!! hahahahaha, they have already. There are four games of chance. During the post-game, when you go to the casino in Tombstone Trail you're awarded with a RIP pass. . I just unlocked the Casino and I'm wondering, is it worth playing any of the games apart from Platoon? I was going to just play Blackjack.
