This is what makes playing craps at an online casino so inviting. In its simplest form, craps is a dice game, and in reality, you can play it with very little equipment, although the green table and colorful chips are nice. You have a variety of craps game software to choose from, in RTG, Microgaming, Playtech, Cryptologic, Net Entertainment and WagerWorks, even though the game is basically played the same no matter where you play it.
