Decimal odds explained\n\n For example, aR$100 bet made at decimal odds of 3.00 would returnR$300 ($100 x 3.00):R$200 in profit and the originalR$100 amount risked. AR$100 bet made at decimal odds of 1.50 would returnR$150:R$50 in profit and the originalR$100 amount risked.

Somewhere on the blackjack table there will be a sign that says, "blackjack pays 3 to 2". All this means is that you, the player, will get $3 for everyR$2 you wager. This is standard, and gives the house slightly elevated odds.
