A player total of 21 on the first two cards is a "natural" or "blackjack", and the player wins immediately unless the dealer also has one, in which case the hand ties. In the case of a tie ("push" or "standoff"), bets are returned without adjustment.

The winning strategy for the two-player version of this game is to always say a multiple of 4; it is then guaranteed that the other player will ultimately have to say 21; so in the standard version, wherein the first player opens with "1", they start with a losing move.

However, the game's single-player campaign can still be enjoyed regardless of the online player count. In conclusion, Black Ops 1 is indeed playable in 2024 on PlayStation 3, Xbox 360, and PC (Microsoft Windows).
