Thanks for the hint!
I removed the ambigous test case.

I changed the tests, now different percentages (1% to 20%) will be tested. Additionally the percentage of holes will be printed in the test name.

I changed it in the test cases.
However for the sample tests accessible by the user, I prefer to not use them, since I think it should be part of the kata to check, if a solution is valid.

Thanks for the hint!
I changed the fixed tests, solutions not checking the last line / column should no longer pass.

I have set the issue to resolved.

I made an update to the sample tests, but I am not sure, if it is enough that way. Could you have a look?
Thanks!

Thanks for the hint!
Since the original intention was, that the robot has to leave the area safely, I made an update to the description.
I hope, it is clearer now.

Thanks for this nice kata!
However I think I found a small inconsitency:
If you submit a solution, which produces a wrong result, I think the grid after applying the solution is printed, not the initially presented grid. This might be confusing.

131 game maps will be presented. (31 basic and 100 random maps)
However the number of "tests" will be higher, since for every presented map several assertions will be done.
You can see how many maps you solved in the logs.
