Great brain exercises First you have to figure out a path to traverse the puzzles. Sometimes this is obvious; other times it's not. After that, you then try to write the program to walk the path. This ranges from trivial to very tricky. Oddly, this game promotes bad programming practices: using recursion when a loop suffices, and not ending the program nicely (most solutions leave junk on the stack).
Nice! Loved this game on the web, love it on mobile. I wish there was a way to change the execution speed: I'd like to test my programs faster. EDIT: Ah there's a way (see answer). Cool!
Nice puzzle All is nice except for synchronising new levels..it takes a lot of time and even not sure that they will come or not..! Plz do somthing for this..!
Great brain exercise! To understand recursion, first you must understand recursion.
