When you are certain of a tile's position, make a long tap on it. The background will change and you won't be able to accidentally rotate it without long tapping the tile again. The less work you need to do to complete your network the better, so Netwalk is scored by the number of clicks it takes you to rotate everything into place. Simultaneous clicks on the same tile will not increase the click counter so you may rotate either way. Similarly, the faster you will complete your network the better, so Netwalk is also scored by the time it takes you to rotate everything into place. There are three levels, different by size: Easy (6x4), Normal (9x6) and Hard (12x8). Infinity levels add extra complexity by allowing wires to wrap from left to right and from top to bottom of the screen. Nightmare level is the most complicated - it is 15x10, infinity, and all tiles with three connections are hidden.
