Doubles hit in approximately 27% of Pick 3 draws — about 1 in every 4 games. A double is any number where one digit appears exactly twice (e.g., 4-4-2 or 7-2-7). There are 270 doubles out of 1,000 possible combinations. When playing a double as a Box bet, you get a 3-way Box (1 in 333 odds, $160 payout) instead of the standard 6-way Box.
Doubles are one of the most important concepts in Pick 3 strategy because they affect box bet payouts, show up with surprising regularity, and behave differently from regular numbers across play types. This guide covers the probability math, how doubles affect your bet type options, and when playing a double intentionally makes sense.
The Probability Math
Understanding why doubles hit 27% of the time starts with counting combinations.
C(3,2) = 3 — the number of ways to choose which 2 of the 3 positions hold the repeated digit. There are 10 choices for the repeated digit and 9 remaining choices for the third digit.
The Three Pick 3 Combination Types
Every Pick 3 number falls into one of three categories. The category determines how many box arrangements exist and therefore which box pay tier applies.
How Doubles Affect Box Bets
The biggest practical impact of doubles is on your box bet payout. A double has fewer arrangements than a single, so it qualifies for the 3-way Box tier — which pays double the prize but has half the win frequency.
Key trade-off: A double Box wins less often (1 in 333 vs 1 in 167) but pays twice as much ($160 vs $80). The expected value is similar — roughly $0.48 per $1 bet either way. Choose a double intentionally when you believe a specific digit will repeat based on recent frequency data.
Strategy — When to Play Doubles
Since doubles appear in roughly 1 in 4 draws, many players specifically target them. Here is when that approach makes the most sense.
Triples in Detail
Triples are the rarest Pick 3 draw type — only 10 possible numbers (000, 111, 222, 333, 444, 555, 666, 777, 888, 999), each with a 1-in-1,000 probability.
