Our Expert Score

78/100

Jass is a high-quality digital adaptation of the traditional Swiss card game. As an expert in trick-taking games like Bridge and Spades, I was impressed by how well this app captures the specific rules and tactical nuances of Jass. The 'Schieber' and 'Differenzler' variants are implemented flawlessly, providing a deep cultural experience for fans of the genre.

The AI is surprisingly sophisticated, utilizing proper signaling and defensive play that will challenge even veteran players. The interface is clean and traditional, allowing the focus to remain on the cards. While it might be niche for those unfamiliar with the Swiss tradition, the inclusion of a comprehensive rulebook makes it an excellent way for new players to learn. It’s a polished, respectful, and highly strategic card game that feels like a premium tabletop experience on your phone.

I love it!
Wed Jul 26 2017 Rera1ler

I give this three stars because I am playing from the US and can't get online play or create an account. My family has played this game for generations and the rules we play by are a bit different? But game play is the same. Thanks for making the app! My family would love to play with the international group of players if the developers can write us in! I look foreword to playing with you all!

Nice interface but occasionally a dumb computer

Hi. The computer player makes bad decisions enough of the time to impact the game play. For example in top down or bottom up they may not lead with the best card.

A near perfect First

I learned how to Jass on a visit to Austria, years ago. Then discovered it was the fore-father of a game we always played in the States, called Euchre. I have since been spreading the word and teaching everyone I know about this challenging, complex, yet deeply satisfying game. Being away from Europe most of the time, I have craved such an app for my iphone. At last here is one. And it's fantastic! Exquisitely designed and well thought-out, given the many afore-mentioned complexities. My only complaint would be one that ultimately can't be remedied until the Austrians make a contribution; that there would be a version with the terminology and cards I learned with-- Laub, Schell, Goss, Bock, usw... And of course, some of the drama that one always encounters in a real game-- the congratulations and dissapointments for Stich, Match, Gegenmatch and the hub-bub associted with such declarations-- is missing. But, hey, I understand! This game is a serious accomplishment given how incredibly varied it is, in real life, from country to country, region to region, dorf to dorf. Well-done!

Very nice user interface

I could not play online yet though, no luck with account activation. It should be possible to have the activation e-mail re-sent, but I have not found a way to. UI improvement: when it's our turn to choose the trump suit, our cards could be more visible, like full screen, not grayed out at the bottom of the screen.

Fun but buggy new update

V1 worked well. V2 crashes randomly, most often when I choose trump playing Shieber Chicane 2500. Bummer! Please fix the bugs! Love the new addition of Swiss German. Update: consistently crashes with iPhone 4.... Bummer again.

Great game

Great game! Well worth it since I don't have players nearby. It also lets my husband learn the game without me. Agree with the previous post about needing more variants. I find the slalom (alternating oben abe & unden ufe) and the half/half (4 of oa or uu followed by 5 of the other) particularly challenging.

Works great now!

Crashed several times in a row by rebooting fixed the problem
