Brag as a game is much more focused on the bluffing aspect of Comparing Games. The word “Brag” In English means to lie in a self-aggrandizing manner.
Hence, players are “Bragging” about the hand that they have, even if in reality it is not very good. This bluffing mechanic exists in Poker as well, Poker will always end in a Showdown unless Players fold.
A game of Brag can continue betting infinitely, with no Showdown ever occurring, as opposed to poker.
