The first release of Cogismo Logic Puzzles shipped with 229 level 1 to 4 puzzles. All of these can be solved. I know because I’ve solved all of them. The first release of Cogismo shipped with 43 level 5 puzzles. I have solved about one quarter of them. As for the other three quarters, there is scope for you to be the first in the world to solve these 😉
Top Priority: Add more puzzles (especially more difficulty level 3, 4 and 5 puzzles). Add a Leader Board (but I’d like to hear peoples ideas on how the scoring should work). Medium Priority: Improve the reports that are available in the Achievements screen. Improving the checking for invalid puzzle configurations on URL startup. What else? I’d like to hear your ideas!
