Tsumego Hero is one of my favorite online tsumego sources, along with 101weiqi. I like the large number of problems from different collections and being able to do subsequent related problems for a topic, in contrast to random problems like on blacktoplay.

Today I decided to give that site another look (did only 101weiqi for a while) and found that they have a time-limited mode with different unlockable levels, very similar to the popular “strength test” on 101weiqi or badukpop. I just did a couple of problem sets and it looks very polished, which is amazing if you consider it’s just made by few people (mainly Joschka Zimdars), doesn’t have ads and no premium subscriptions. (You can get some donation perks but it only requires a one-time donation and you really don’t need the perks like more board textures.)

My personal approach is doing tsumego from different sources, I like both apps, different websites but also have tsumego books and do tsumegos from go journals. I thing seeing different styles is useful and that way it’s more fun and less monotonous.
