Level 132 starts with all red dots on the board. How can you go wrong?
I’ve tried a few combinations, from single squares to completing the entire perimeter, and it seems that tracing the entire perimeter doesn’t set you up any worse than a simple square does, and you get a few bonus dots from the bombs left behind.
The key from here is to think very carefully about your path to getting your next square setup. If you botch an opportunity, you’ll end up digging yourself out and wasting a ton of moves.
You should be able to make a square every other move or so. If you spend more than 3 moves setting up a square, seriously considering bailing on the game.
The good news is that if you complete squares with regularity, you’ll finish with plenty of moves left.
