Does a straight beat three of a kind?
Yes — a straight beats three of a kind in poker.
Does a straight beat three of a kind?
This is one of the most common poker ranking questions, and the answer never changes: a straight wins against three of a kind. Because a straight is rarer and ranks higher than three of a kind, it wins the showdown every single time, no matter the suits or the cards inside each hand.

Why
Three of a kind feels powerful the moment it lands — trip aces or trip kings look unbeatable to a newer player — but a straight is significantly harder to make. Three of a kind comes up roughly once every 47 five-card hands, while a straight lands roughly once every 255, making a straight more than five times rarer. That gap is exactly why five connected cards of mixed suits outrank three matching cards plus two side cards, even when the trips are made of high pairs. Rarity, not raw card value, decides the ranking, which is a distinction worth internalizing early.
Example
One player shows 9♦ 8♠ 7♥ 6♣ 5♦ (a straight); the other shows 8♣ 8♦ 8♠ K♥ 3♦ (three of a kind). A straight outranks three of a kind, so the straight wins.
A second example
Board: 9♠ 8♦ 7♣ 4♥ 4♠. Player A holds T♦ J♦ and makes a jack-high straight (J-T-9-8-7). Player B holds 4♦ K♣ and makes trip fours with a king kicker. Trip fours looks sturdy on a paired board, but the straight was already there — and it wins.
In real play
This is a common river cooler: one player rivers trips on a paired board and bets big, not realizing the board already had three connected cards that let an opponent make a straight two streets earlier. Before firing a big bet with trips, scan the board for three cards within a five-card spread — if they are there, a straight is always possible. Run the specific board through the equity calculator when the texture looks connected, and see the full straight guide for how the hand is built. Because trips is dealt far more often than a straight, expect this exact spot to come up repeatedly over a long session, not as a one-off fluke. Slowing down to read the board’s connectivity before the river costs nothing and saves real chips.
How each hand is built
Here is exactly what each hand requires, side by side, so there is no ambiguity about why one outranks the other:
- Straight: five sequential cards, mixed suits.
- Three of a Kind: three cards of one rank, plus two unrelated side cards.
Odds and frequency
How often each hand is dealt in a random five-card poker hand (a rarer hand always outranks a more common one):
- Straight: 1 in 255
- Three of a Kind: 1 in 47
The numbers line up with the ranking: a straight is the rarer hand of the two, which is exactly why it ranks higher and wins the showdown.

Key takeaway
Players often confuse the two because both are five-card hands, but the ranking is fixed: a straight is always the winner. When in doubt, work down the ranking chart from the top and the higher hand always takes the pot.
