Have you tried laying at a B+M, No clicker there, but i go down column 1, up column2 and come back down column 3, quiet easy when you've done it thousands of times, just keep calm as you place the units, as your there for more than 40 spins your subconscious mind will help in laying, just keep saying to yourselves the non-hit that are left as they get hit.
