Thirteen is Tiến lên, the Vietnamese climbing card game, against three computer players. Beat the play on the table with the same kind and a higher card — singles, pairs, runs and pair runs — chop the 2s with a four of a kind, and be among the first to empty your hand.
Southern rules: 3 is the lowest rank and 2 the highest; spades are the lowest suit and hearts the highest.
A four of a kind or three pairs in a row chops a single 2; a four or four pairs in a row chops a pair of 2s.
Pass and you sit out until the next round, when the last player to play leads anything.
The 3 of spades starts every game; the first game is coached.
Finish in the top two to pass the level, first out for three stars.
Tiến lên — “go forward” in Vietnamese, often written Tien Len and also known as Thirteen or Killer 13 — is the most popular card game in Vietnam, and Thirteen plays its southern rules (tiến lên miền Nam). If you know Big Two (Choi Dai Di) from Hong Kong or the Philippines, it is a close cousin: a climbing game where each play has to beat the last, and the aim is to shed every card in your hand.
The skill is in timing. Lead your low runs and pairs early, because they are hard to get rid of later; keep your 2s for when you need to take control and lead; and save a four of a kind to chop an opponent's 2. Watch the players with only a few cards left and don't hand them the lead — passing is often the strong move, keeping your best cards for later. Thirteen is free on crokocat and plays in the browser on desktop, phone and tablet with no download, and the coached first game makes it an easy way to learn Tiến lên.
