Wanna guarantee you never have to call for takeout, or wind up being designated driver for the night? Follow this "can't lose" strategy for the ultimate decision method – ROCK, PAPER, SCISSORS.
Tip 1. Watch out for those trends. A lot of players often switch to what just beat them. They will most likely throw rock after just being smashed by one on the previous play. Instead, throw paper on the next round for a near certain victory.
Tip 2. Most newbies almost always lead with rock, so open with an easy win by starting with paper.
Tip 3. Players almost never throw the same thing three times in a row. If they throw two papers in a row, toss a rock out there next to take that round.
