Learn which bombs beat single, paired and triple 2s in Thirteen, why exact pair-run lengths matter, and when passed players can still respond.
What Can Beat a 2 in Thirteen?
In Thirteen, also known as Tiến Lên or Tien Len, a 2 is the highest ordinary rank. That makes it powerful, but it does not make every play of 2s unbeatable.
Certain combinations can act as bombs, sometimes called chops, and beat eligible 2s without matching the combination type normally required. A higher-suited 2 can also beat a lower-suited 2 through ordinary single comparison.
Bomb rules vary between versions of Thirteen. On Solitaire Arcade, a single 2, a pair of 2s and a triple of 2s each have specific bomb responses. Bigger is not automatically better.

The Bomb Rules at a Glance
Single 2: four of a kind or exactly three consecutive pairs.
Pair of 2s: exactly four consecutive pairs.
Triple of 2s: exactly five consecutive pairs.
These are the bomb responses, not a replacement for ordinary comparisons. If you can answer with a higher combination of the same type and size, that remains an ordinary play.
Four of a kind is a special answer only to a single 2. Consecutive-pair bombs must have the exact length required for the current group of 2s.
What Can Beat a Single 2?
A single 2 can be bombed with four of a kind or exactly three consecutive pairs.
Suppose the current play is 2♦. Four 9s are a valid bomb, as is 7–7, 8–8, 9–9. Neither needs to outrank the 2. Four Jacks work the same way against 2♥: any four-of-a-kind has the required shape, and a later player who has not passed can still climb with four Queens, Kings, Aces or 2s.
If you hold only two consecutive pairs, that is not enough. Two consecutive pairs are not a legal combination on Solitaire Arcade, even as an ordinary lead. Suits can mix; each rank needs exactly two cards and the ranks cannot have gaps.
There is also a normal answer to 2♦: 2♥. No Ace or lower-ranked single can beat a 2. The 2♥ is the highest ordinary single, so beating it while the battle continues requires an eligible bomb.
What Can Beat a Pair of 2s?
To bomb a pair of 2s, you need exactly four consecutive pairs.
For example, 2♣ + 2♥ can be bombed with:
6–6, 7–7, 8–8, 9–9
Three consecutive pairs are not enough. Four of a kind is not a valid bomb against a pair of 2s either, even if you hold all four Aces. The rank of those Aces cannot replace the required combination type.
A pair of 2s can also lose through ordinary suit comparison. For example, 2♠ + 2♥ beats 2♣ + 2♦ because the highest card in the first pair is 2♥. That is a higher pair, not a bomb.
What Can Beat Three 2s?
A triple of 2s requires exactly five consecutive pairs to bomb it.
For example, 2♠ + 2♣ + 2♦ can be bombed with:
4–4, 5–5, 6–6, 7–7, 8–8
That is a ten-card combination, a large part of a thirteen-card hand. Four consecutive pairs, three consecutive pairs and four of a kind cannot substitute for it.
There is no higher-ranked triple. With only four 2s in the deck, another player cannot hold a separate triple of 2s to win on suit either.
Why Exact Length Matters
The consecutive-pair requirements are exact lengths, not minimum lengths. Three pairs bomb one 2, four pairs bomb two 2s, and five pairs bomb three 2s.
You cannot play all eight cards of a four-pair run to bomb a single 2. That selection is the wrong length.
However, holding a longer run does not prevent you from choosing a legal shorter section. If you hold pairs of 6s, 7s, 8s and 9s, you can select just 6–6, 7–7, 8–8 to bomb a single 2, leaving the pair of 9s in your hand.
Check the cards you are selecting, not just the combinations your full hand could form. A longer run can offer choices, but the submitted play still has to match the rule.
Bombs Do Not Override Ordinary Non-2 Plays
Suppose someone plays a single Ace. You cannot answer with four 8s simply because four of a kind can act as a bomb. The Ace is not an eligible 2 play.
Likewise, consecutive pairs cannot replace a response to an ordinary straight, and four of a kind cannot answer a pair of Kings. Normal matching rules still apply.
These combinations can be played normally when their type matches. Four Kings beat four Queens, and a higher three-pair run beats a lower three-pair run. That is ordinary climbing, not a universal bomb override.
Can One Bomb Beat Another?
Yes, but the response must match the current combination's type and length and be higher.
If four 7s bomb a single 2, four Queens can beat them. A three-pair run cannot replace that four-of-a-kind response.
If 5–5, 6–6, 7–7 bombs a single 2, a higher three-pair run such as 6–6, 7–7, 8–8 can beat it. A four-pair run cannot answer simply because it is longer.
For equal-length pair runs, compare the top pair's rank first. If that rank ties, compare the highest-suited card in the top pair. A run ending in 8♠ + 8♥ beats one of the same length ending in 8♣ + 8♦.
There is no general ladder where every larger bomb defeats a smaller bomb. Once the current play changes, judge your response against that new combination.
2s Cannot Be Used Inside Pair Runs
Consecutive-pair runs cannot contain 2s, and ranks never wrap.
Q–Q, K–K, A–A is a valid three-pair run.
K–K, A–A, 2–2 is not.
The same exclusion applies to straights. A 2 is the highest ordinary rank, but it does not extend a run beyond Ace. For the full combination definitions and suit tiebreakers, see Thirteen card rankings and combinations.
Can You Bomb After Passing?
Passing locks you out of ordinary play until the battle clears. On Solitaire Arcade, there is a narrow exception: you can still bomb eligible 2s when your normal turn arrives.
For example, if you passed earlier and the current play is now a single 2, four 9s are a valid bomb on your turn. You cannot jump in before your turn.
The exception depends on what is currently on the table. If someone else has already bombed the 2 with four 8s, your earlier pass prevents you from answering with four 9s. The current play is now four of a kind, not an eligible group of 2s.
Similarly, a passed player cannot use a higher-suited single 2 as an ordinary response. Re-entry requires the qualifying bomb exception.
Once you successfully bomb eligible 2s, your pass lock is removed and you can contest later plays normally when your turn comes around.
Can a Bomb Undo Someone Going Out?
No. On Solitaire Arcade, a player's finishing place is secured as soon as a legal play empties their hand. A later bomb cannot undo that finish.
If another player goes out with a 2 and the battle continues among the remaining players, an eligible bomb can still matter for who controls the next lead. It cannot take away the place already earned.
This is why keeping a bomb is not a guarantee that you can stop someone finishing with a 2. Once they have legally played their final cards, they are out.
Should You Use a Bomb Whenever You Can?
Having a legal bomb does not mean you should spend it at the first opportunity.
Bombing a single 2 with three consecutive pairs removes six cards and may help you take the lead. But another player may beat your run, and the cards left in your hand still need a route into play.
Before committing, look at what remains. Will you be left with a useful pair, a straight or several awkward singles? Would selecting a shorter section of a longer run leave a better finish?
Opponent card counts can tell you whether they have enough cards to hold a bomb, but they do not reveal the actual combinations. A player holding six cards might have three consecutive pairs, or none at all.

The Three Bomb Rules to Remember
Against a single 2, use four of a kind or exactly three consecutive pairs. Against a pair of 2s, use exactly four consecutive pairs. Against a triple of 2s, use exactly five.
Check the current play, select the required combination and wait for your turn. A bomb creates a specific exception; it does not remove the rest of the rules.
