If you have no qualms about bearing the stigma of being cheater...

Pause the game to give yourself a chance to look over the pattern without time pressure.
The most obvious line at the start of a screen is often a trap. After taking the bait the pattern goes out of sequence making it more difficult to make new lines. On the more difficult levels you have to plan your sequence of moves way ahead, hence the usefulness of pausing to learn a stage.
