While there are 40 different legal places to gamble in Costa Rica, you would be hard pressed to find even one that would be equal to even the smallest casinos in Atlantic City, Vegas, or Macau. Many of these establishments are offshoots of hotels. In a town like Vegas, you have casinos that also serve as hotels, whereas Costa Rica has hotels that happen to have small casinos.
Most of these casinos have around 2 to 5 table games and about a dozen or so slot and video poker machines. In addition, many of these establishments are somewhat sparsely populated, meaning that you will be playing without much interruption whatsoever. The largest casino in Costa Rica is the Del Rey Hotel and Casino in San José. In this case, largest mean that there are 60 slot machines and 10 table games.
Earlier I said that there were 40 legal establishments in Costa Rica. There are also numerous "underground" or illegal casinos in the country. You want to be certain that the establishment you are playing at is a legal one. Sticking with those attached to a hotel will be your safest bet while playing in Costa Rica.
What You Can Play
While casinos in Costa Rica are smaller, they still offer many of the same casino games that you would expect in larger establishments. Slot machines, keno, sports betting, craps, roulette, Pai Gow Poker and much more is available. The Casino Del Rey hosts Texas Hold'em poker games as well.
One big difference between Costa Rica and other destinations is that most casinos there consider blackjack to be illegal. Instead, they play a variant called Rummy. Many of the same rules of blackjack apply except that if you draw either three of a kind in three cards or a straight (ex. 4-5-6), then you have a "Rummy" and are paid three to one. Also, there is no bonus for being dealt a blackjack.
While there are numerous casinos in Costa Rica, they are more a touch of luxury and extracurricalr form of entertainment for hotel guests and tourists. They are a great way to pass some time or unwind after a long day but, like Vegas, you probably are not going to strike it rich there.
