If you want to do tsumego but can’t resist clicking through when doing electronic tsumego with an app, try doing some tsumego with paper or .pdf instead.
This website provides series of tsumego in .pdf format, without solutions: https://tsumego.tasuki.org/
The first series, “Cho’s elementary”, should be doable at your level. Every diagram is a tsumego. It is always black to play. There is no indication, just find the best move with Black (which usually means either kill white, or make black live).
If you print them, mark your answers on the sheet with a pen, then upload a picture in this thread, we can tell you which ones are correct and which ones are not. This way you won’t have the answers unless you find them by yourself.
To mark your answer on a diagram: mark “1”, “2”, “3” directly on the intersections, where 1 and 3 are black moves and 2 is a white move.
Of course you can use an image editing software or a pdf annotator software, instead of printing and using a pen then taking a picture.
Note: this series contain 900 problems, more or less arranged in order of difficulty. I suggest doing them in the order they are. Except for problems 26 to 34, which are much harder, so I suggest skipping those.
Edit: Oh. We’re five years later.
