What is Trex?
Trex – also spelled Trix and known in Arabic as تركس – is a trick-taking card game for four players using a standard 52-card deck. Each player is dealt 13 cards. The game is split into kingdoms: in every kingdom one player is the owner and picks the order of five different contracts. Four contracts are about avoiding penalty cards, and one – Trex itself – is a race to get rid of your cards first.
Because the owner chooses when to play each contract, good Trex is all about reading your hand: call Diamonds when you are short in diamonds, save Trex for a hand full of jacks, and double the Queen your opponents are forced to take.
Trex rules and scoring
These are the exact values used in the app. The four penalty contracts add up to −500 points per kingdom – exactly what one Complex deal costs – while a Trex round hands out +500.
| Contract | Goal | Points |
|---|---|---|
| King of Hearts | Don't take the King of Hearts. | −75 (−150 if doubled) |
| Queens | Don't take any of the four queens. | −25 each (−50 if doubled) |
| Diamonds | Don't take diamond cards. | −10 per diamond |
| Lutoosh (Slaps) | Take as few tricks as possible. | −15 per trick |
| Trex | Build suits up and down from the jacks and empty your hand first. | +200 / +150 / +100 / +50 |
All penalties in one deal
King of Hearts, Queens, Diamonds and Lutoosh are scored together in a single hand, followed by a Trex round.
Turn defence into attack
Hold a Queen or the King of Hearts? Double it. Whoever takes it loses double – and you collect the base points.
Play alone or as a team
Every player for themselves, or sit opposite a partner and share the score.

Frequently asked questions
Is Trex the same game as Trix?
Yes. Trex, Trix and تركس are the same Levantine card game: four players and five contracts – King of Hearts, Queens, Diamonds, Lutoosh (Slaps) and Trex.
How many players does Trex need?
Exactly four, each dealt 13 cards from a standard 52-card deck. In the app, empty seats are filled by AI players, so you can always start a game.
What is the difference between Kingdom and Complex?
In Kingdom each player owns a kingdom and chooses all five contracts once – 20 rounds in total. In Complex the four negative contracts are played together in a single deal, and the owner also plays one Trex round.
How does doubling work?
In Queens and King of Hearts, a player holding the card can double it. Whoever takes a doubled card loses twice the points (−50 per queen, −150 for the King of Hearts) and the player who doubled gains the base value.

Yes. Create an online game and tap Invite friends. The link opens the game directly, or takes your friends to the store to install Trex first.
