Cool game! Even after I studied circuit architecture this is one hard for me... Great idea, useful for practicing binary to decimal conversion! Would be nice to automaticaly accept the answer without pressing enter...
Thanks for the feedback. Interesting thought, but since numbers spawn randomly I am not sure how it will play out if you have, lets say 20, 2, 1, 21 appear in the grid, you see 20 first and try to enter it but it hits 2. Now you have to start over again to hit 20. I see it getting bit complicated.
