(free) Apps for Go Problems (Tsumego/Life & Death)

different times newbees freshly registrating on Go servers like OGS or KGS come up with the question about sources for Tsumego training…. part of Go problems (life & death) – http://senseis.xmp.net/?LifeAndDeath

specificly about Tsumego… http://senseis.xmp.net/?Tsumego%2FTraining

Training Tsumegos helps to keep (or get) your Go mind flexible, it gives beginners an understanding how stones and moves can collaborate to neutralize attacks threatening enclosed groups and help a deeper (pre-)reading about tricky situtations.

Just playing wont give a beginner a deeper feeling and idea about what an opponent with higher skills might use a set of stones or single moves, tools like KO or Seki to kill or less neutralize a group especially beginners expected to be alive with.

There are great websites for Go problems, e.g. http://www.goproblems.com, http://www.ootakamoku.com and others (more links here:http://senseis.xmp.net/?ProblemsAndExercises ).

Personally I prefer apps on a smartphone, as you can have some nice **Tsuemgo problems** with you, e.g. as “Go problem of the day”.
____________

Here some I have installed. Personally I use a Samsung Galaxy with Android. All apps are cost free !

– First of all my favorite, its Wbaduk with more than 2,000 problems. You get access to this hugeTsuemgo database with a cost free online account too ( http://www.wbaduk.com/ ) as on Wbaduk often are live streamed games of High Dan Professionals (e.g. Jubango 2014 with Gu Li and Lee Sedol).

Rec.: The 2,000 Tsumegos are structured in different difficulty levels and for grades (kyu and dans)…

– My 2nd favorite is Tsumego Pro (Go Problems). It delivers for every day 6 new Tsuemgo problems, “easy”, “medium” and hevy” (each 2). Lots of fun to take these challenges…

– Shortly installed ANDROID GO Problems, so yet I have no deeper experience with… the menue isnt immediatelly to understand. So needs some “try and error” clicks to understand the function.

– Go Free is the most exotic design (very traditionally), inclusive a GO computer (not the best like Zen or Crazystone) on different board sizes (19×19, 13×13, 9×9)

– Another app is simple named Tsumego, but I have some troubles to handle it well. Maybe its just my personal expectation. I expect from an app, that I can understand the menu intuitively, and not reading lots of “thick handbooks”.

There are some more Go apps you can find on Google Play for playing and training Go, e.g. WeGoLite, ElyGolite, Hactar Go Lite, Go Joseki, Go Tesjui, Go strategic move or Online Go. Give it a try and feedback about (+) and (-)

If you know about other apps, e.g. for iPhones (iTunes), feel free to post it in this thread. 🙂 – Have fun with GO !
