Welcome to the Official State Domino game of Texas! Texas 42 is a trick taking game similar to bridge or spades. Invented in the late 1880s, it has become a tradition across generations of players.

The sole motivator for the development of this app has been to create an AI that doesn't make the users wish they spent their 2 dollars on a soda instead of frustrating computer play. Much work has been made into creating an AI that makes the same moves you would. Since you don't have the same play style as everyone else, you can set each computer player to have one of 3 specified play styles "Conservative", "Normal", or "Aggressive". You can mix and match these styles as you see fit and can change them at any time in the game.

A conservative player will tend to bid lower than the rest of the players. Its main focus when it has the lead is to draw all the trumps in play before moving on to non-trumps. If the conservative player does not have the highest trump, it will tend to lead with a junk/punt tile to draw out the higher ones, while holding on to tiles with count until it knows it can win with them.

A normal player will tend to bid higher than a conservative player. Its main focus is holding on to its trumps for cases where count is on the table. If it does not have the highest trump it will tend to attempt to punt to its teammate.

An aggressive player is a mixture of the two. It tends to push the bid to 31 or 34-36 with weaker hands than the other two and is more willing to bid marks if it has a strong hand. It is also willing to lay down trumps with 5 counts in an effort to draw out the ones covering the 10 count. Its more willing to play count at risk of hoping its partner will win the trick.

For bidding purposes, your partner will respond to your bid. If you bid 30, you are indicating to your partner that you have a helping hand and it will be much more likely to outbid an opponent win the bid.

Here's what some beta testers have had to say about the app:

"The AI has been impressive for me so far, not a single play that I've seen has been stupid yet and I've probably played around 10 games. Very solid game for my experience"

"I really like your idea of the different styles of play and I think you are pretty close to that reality."

"To date it is the best one out there. I have never felt like I was playing true 42 on the other apps."

Partner play questionable

I love the game but my partners play is sometime very lacking, especially when playing splash. I just played a game where he had bid 31 and I had 5 doubles so I bid 2 marks and went splash. The led out his trumps then led an off which I caught with a double. I then led a couple more doubles. On the next to the last trick he played his last Trump then led another off, one I had already played the double for. The other team caught it and set us. Why have splash as a part of the game if you aren't going to program the partner to play it the way a normal person would. Actually that applies to normal play as well. Like when I Trump the other team and my partner plays an off when he could have played the 6/4. Then loses the 6/4 to the other team on the next trick. ??????

Program error

Tried to play multi game with four people in tha Back yard for over an hour and could not get the game to work consistently, it worked for two tricks and would loose a player , some times a player would only get four dominoes! Terrible, we finally gave up. I’ve noticed app never gets any updates.

Multiplayer Issues

I’ve been able to complete ONE full game with an invited opponent!! It just won’t work! Needs more tweaking I guess! Love playing against the computer, would really love to play against friends and family that I encouraged to get the app!!
