How to Win More at Rock Paper Scissors

You will not find a guaranteed win. You can leak less information than the other person. That is the whole edge.

Do these

1. Decide your first throw before you look at their face, or before the buttons animate.
2. After you lose, do not automatically throw the thing that just beat you.
3. After you win, do not automatically repeat.
4. In a long match, mix on purpose. Count to yourself if you have to.
5. Play best of 5 if the other person is readable; habits need room.

Stop doing these

• Announcing 'I never throw rock' — now you throw rock, or they know you do not.
• Watching their cursor hover on a symbol in a bad UI. (Duetly does not reveal a hover as a choice.)
• Playing best of 1 and calling the result skill.

Then go use it. Play Rock Paper Scissors with a friend in a private room. If they cannot play right now, the computer match will remind you that systems fail on dice.
