Put streets around the numbers so that you make one big loop around the city. Click around the edges of the blocks to either put streets in or block them off... But, you have to follow these rules:

1) The number of walls around a block must match the number written on the block.

2) The walls must form ONE big loop only.

3) No "dead end" streets allowed. No branches can stick out of the loop.

4) All streets you build must be part of the loop. There cannot be extra streets.

The game will tell you when you are breaking a rule.

TIP: If a street should be blocked off, always do it because that will lead to other moves!
