Blackjack Darts

Score as close to 21 as possible without going over, mirroring the classic card game of Blackjack. Each round, players throw up to three darts, accumulating points toward the target of exactly 21. Going over 21 is a bust, resulting in zero points for that round.

A Blackjack — reaching exactly 21 with only your first two darts — is the highest-ranking result and beats a plain 21 achieved with three darts.

Blackjack Darts is played on a standard dartboard with standard segment values. Two or more players may compete. Each player needs three darts, and a scoreboard should be prepared to track each player's round-by-round totals.

To determine throwing order, each player throws one dart at the bullseye; the closest dart throws first, with subsequent positions determined by proximity. In multi-round formats, the throwing order may rotate each round to ensure fairness.

The target score each round is 21. No starting score is recorded — players build toward 21 from zero with each visit to the oche.

Each round, players take turns throwing up to three darts, accumulating a running total for that round. The goal is to reach exactly 21 or as close to 21 as possible without exceeding it. Crucially, a player may choose to stick (stop throwing) after any dart — after the first, second, or third — if they are satisfied with their current total or fear busting with another throw.

Standard dartboard segment values apply:

• Single segment: face value (1–20)
• Double ring (outer narrow ring): 2× the segment number (2–40)
• Triple ring (inner narrow ring): 3× the segment number (3–60)
• Outer bullseye: 25 points
• Inner bullseye: 50 points

Bust rule: If a player's running total for the round exceeds 21 at any point, that player has busted and scores zero for the entire round. The bust takes effect immediately — any remaining darts in the player's hand are forfeited.

For example, if a player's first dart lands in single 14 (total: 14) and the second dart lands in single 10 (total: 24), the player has busted and scores zero. The player does not throw a third dart. Conversely, if the first dart is single 14 and the second dart is single 7 (total: 21), the player has hit exactly 21 and should stick — there is no benefit to throwing a third dart.

Blackjack: Reaching exactly 21 with only the first two darts constitutes a Blackjack. A Blackjack outranks a standard 21 achieved with three darts. For instance, hitting single 11 followed by single 10 (total: 21 in two darts) is a Blackjack, whereas hitting single 7, single 7, and single 7 (total: 21 in three darts) is a plain 21. If two players both achieve a Blackjack in the same round, their results are tied.

Points are tallied by adding the face value of each dart thrown during the round, using standard dartboard multipliers:

• Single: 1–20 points (face value)
• Double: 2–40 points (2× the segment number)
• Triple: 3–60 points (3× the segment number)
• Outer bull: 25 points
• Inner bull: 50 points

A player's round score is the sum of all darts thrown before sticking or busting. If the total exceeds 21, the round score is zero. For example, hitting triple 7 (21) with a single dart scores a perfect 21 — and since only one dart was used, this also qualifies as a Blackjack. Hitting double 10 (20) followed by single 1 (total: 21) is a Blackjack in two darts. Hitting single 8, single 6, and single 5 (total: 19) scores 19 for the round.

Round results are ranked as follows: Blackjack (21 in two darts or fewer) beats plain 21 (in three darts), which beats any score of 20 or lower. Among non-21 scores, the higher total wins. A bust (zero) is the worst possible result.

The player with the highest round score wins the round, subject to the Blackjack hierarchy: a Blackjack beats a plain 21, a plain 21 beats any score of 20 or below, and a bust (zero) loses to all other results. If two or more players tie with the same score (including both achieving Blackjack), the round is drawn.

Blackjack Darts may be played as a single-round contest or over multiple rounds. In multi-round play, the overall winner is the player who wins the most rounds over an agreed number (e.g., best of 5 or best of 7). Alternatively, players may keep a cumulative score across rounds, with the highest cumulative total after a set number of rounds determining the winner — though busted rounds still contribute zero to the cumulative tally.

Casino Blackjack (Casino Board Version): This variant is played on a speciality casino-style dartboard where segments display playing card suits and values rather than standard numbers. In this format, an Ace counts as either 1 or 11 (as in card Blackjack), court cards (Jack, Queen, King) count as 10, and spot cards count as their face value. A true Blackjack — an Ace paired with a 10-value card (10, Jack, Queen, or King) in the first two darts — beats any other total of 21. An additional rule requires that scoring cards must be of different suits; hitting two cards of the same suit invalidates one of them.

Skilled Casino Blackjack: A more demanding variation of the casino board version in which all scoring darts must land in treble or double segments to count. Furthermore, achieving a Blackjack under these rules requires hitting two trebles with the first two darts. This variant significantly raises the difficulty and is intended for experienced players seeking an additional challenge.

21 Darts / Twenty-One: These are alternate names for the standard game described above. Rules are identical; the name simply reflects the target score rather than the card-game analogy.

Know your one-dart 21: Triple 7 scores exactly 21 with a single dart — the only one-dart Blackjack on the board. If you are confident in your accuracy around the 7 segment, leading with triple 7 is the most efficient path to a perfect score.

Plan two-dart Blackjack combinations: Memorize common two-dart paths to 21. For example: single 11 + single 10, double 7 + single 7, single 20 + single 1, double 10 + single 1, or single 14 + single 7. Having multiple routes in mind lets you adapt after your first dart lands.

Stick on 18 or higher: If your first two darts total 18, 19, or 20, seriously consider sticking rather than risking a bust. Only three single segments (3, 2, or 1) would improve an 18 without busting, and the reward for gaining a point or two rarely outweighs the penalty of scoring zero. Risk assessment is the heart of this game.

Use low-value segments to approach safely: If your first dart scores high (e.g., single 17), resist the temptation to aim at another high segment. Instead, target the low end of the board — single 1, 2, 3, or 4 — to inch toward 21 without overshooting. Controlled, conservative darts win more rounds than aggressive ones.

Watch your opponents' scores before deciding to stick: If you are the last to throw and your opponents have all busted or scored low (say, 15 or below), you can safely stick on a modest total like 16 or 17 and still win the round. Adjust your risk tolerance based on the scores already on the board.
