Batman Dice is similar to Zombie Dice. The biggest difference is that in Batman Dice, you have a special character. That character is a Batman villain. They each have a super power, like Catwoman, who gets two points instead of one with blue cash.
There are three die rolls: Cash, Bat Signal, and the Doorbell. The Cash is like the brains in Zombie Dice, you want it. The Bat Signal is the shotguns, if you get three then all the cash you collected goes away. The Doorbell is like the footsteps, you just re-roll them.
I like the portability of this game. It is small, confined, and very fun. It comes in a round container that you also use as a dice cup. Just like Zombie Dice and Dino Hunt Dice, it uses the three normal symbols, granting that Zombie Dice also has a Christmas edition with some tweaks.
It is easier to pack for close spaces than to play in them. The dice make it hard to play without a given surface and a very controlled roll. I would not take this on an airplane, as there would be too much risk of losing the dice.
I also enjoy that they put in characters. This creates some diversity, which is a good contrast to Zombie Dice, where there are no special tweaks per player.
