Dinsun Expert Review

Our Expert Score

80/100

Mü (or Mu) is an incredibly faithful and stylish adaptation of the classic card game. For those who aren't familiar, Mü is a complex trick-taking game that involves a lot of bluffing and strategic bidding. This app does a fantastic job of making those mechanics accessible.

The interface is clean and doesn't get in the way of the cards, which is essential for a game where you need to keep track of so many variables. The AI is surprisingly competent, providing a real challenge even for experienced players. It's a niche title, but for fans of German-style card games, this is an absolute gem on the App Store.

Bid reference

When I tilt screen the bidding chart no longer comes up.

Great Game!
Tue Mar 01 2016 Princess IME

Update...this game has been updated and no matter how many times you click on the disabled tips button, once you start the game again the tips come back. Then when I change the settings to move the game from normal to fast that only lasts for that time while the games open when I go to open it back up again later it's back to the normal speed. I get that they are not probably going to be making any corrections but I sure wish that they would. ——————— This is a great game and excellent alternative for Rook, which doesn't seem to yet be available as a computer/ipad game. The only downside I've come across is that the game sometimes ends before any player reaches 400 points (my setting). Most recently for me the high score was 378 when the game ended. Please fix!

A trick-taking card game that's a real treat
Wed May 19 2010 GSwarthout

If you enjoy trick-taking card games like Hearts, Spades, Bridge, or Wizard, you will be in heaven with Mü. With its slick, faithful, and feature-chocked adaptation of Frank Nestel's clever rule set, it is obvious that this game was a labor of love for developer Steve Blanding. Available in the physical world in the card game collections Mü & More and Mü & Lots More (both highly rated on BoardGameGeek), Mü offers a depth of strategy almost unheard of in card games. So much so that even with a thorough tutorial, I would highly recommend reading the in-game manual in its entirety. One huge point in favor of this particular adaptation is the ability to play with up to five other local users through Bluetooth. Mr. Blanding has devised a way around the typical two-player limit to such wireless communication, one that I hope other developers will utilize in the future. Mü also saves automatically and transparently at every turn, a necessary feature for a longer game such as this. And I have to admit that another point in favor of this app is that the game plays in portrait orientation, though one can turn his/her device on its side to view the detailed scoring charts. If you carry any fondness at all for card games, you owe it to yourself to give this app a try. It will provide you with countless hours of enjoyment for a mere pittance, whether you play it alone or with friends.

Needs work
Tue Sep 25 2018 Mcv47

I wrote the developer an email, but the biggest flaw is that the game plays as if everyone (AI) can see each other’s cards. Makes it unplayable.

Has the developer stopped supporting the game?
Sat Dec 09 2023 Mohamad Sobh

When I updated for iOS 17, the app stopped working, are there plans to update it?

Poor play

The engine for this game is full of misplays. It takes a great game ruins it by making bad plays.

Take the time to understand it and you will be rewarded

This is not a mindless bird-thrower game to while away the hours. It's a first-class thinking game that will challenge you at every turn. The trump rules are odd and take a little time to get used to. I played the first couple games getting a hint on every play and had no idea why the suggestion was strong or weak. But when it fell into place in my head, it was beautiful. I play this all the time now, grabbing a round or two if I have a few minutes. An excellent game and perfectly suited for the Ipod. My only beef is a small one. Sometimes when I try to tap a card on the left side of a full hand, I'll accidentally hit the trash can instead and it'll ask if I want a new game. I can always back out of it, but it's a minor annoyance.

Whoa, and you thought Bridge could be a pretty deep card game?
Sun Jan 24 2010 Lord Gek

While I still barely know what I'm doing, this game is indeed pretty complex and the AI seems pretty competent. At its heart, think of a game almost like Bridge with the weird twist that in each hand teams are chosen. Basically each hand starts with players bidding for the honor of being the "Chief" (this is the guy who will determine the main trump and is entitled to a bonus if he succeeds), the second place bidder is the "Vice" (this is the guy leading the opposition against the Chief and has the option of declaring a secondary trump). The Chief then chooses a partner (anyone but the Vice), and the rest of the players will help out the Vice in trying to stop that sneaky bastage of the Chief from succeeding with his bid. This twist of never knowing from hand to hand who you'll be teaming up with is definitely unique. Another very original concept in this game is how the game not only can have a Major (the Chief's trump) and Minor (the Vice's trump) trump, but either the Chief or Vice can declare either Color or Numeric trumps (if a numeric trump is declared, say "5", now all 5s become a separate suit unto themselves of equal rank with the first player to play this trump in the given trick the winner). This concept of two trumps can get weird, to be sure, especially if, say, the Chief calls Red and the Vice calls 7 as his trump. In such a case Red would be the major trump, all 7s the minor and the Red 7, the highest ranking trump of all! Good mind expanding fun with my only gripe being that the game won't display your trick point total of your current hand so far. The dev said this omission is intentional but maybe if enough people whine about it he might work it into an update.
