Blackjack is fun in the casino’s — it really is, but, just like poker — there’s quite the range of possibilities to enjoy a game of blackjack in your own home… It’s obviously not the most legal activity in most countries if there’s real money involved — but as long as you keep it private, you should be ok. 
Anyway, what you need:
- One or more decks of cards
- A table
- Casino chips (poker chips)
- Maybe even a blackjack table lay-out
I suggest using a single deck setup for homegames. It allows for more suckout and makes card counting way easier. It does mean cards should be shuffled, which could slow down the game somewhat. If you want to play at high velocity — use multiple decks.
And… have fun!
