Rock Paper Scissors

Rock Paper Scissors is a simultaneous hand game with three choices. The winner is determined by this triangle:

• ✊ Rock crushes ✌️ Scissors
• ✌️ Scissors cuts ✋ Paper
• ✋ Paper covers ✊ Rock

You and the computer pick at the same time. If it's a tie, play again!

• Open with Paper —Studies show 35% of players start with Rock. Counter it!
• Vary your patterns —Avoid throwing the same choice more than twice in a row.
• Watch for the "Winner's Curse" —After winning, people often repeat. After losing, they tend to switch.
• Rock after a Rock-Rock tie? Don't. Most people switch from Rock after a tie.
• Stay unpredictable —Mix up your timing to make pattern-reading harder.

Competitive RPS players can win 70-80% of matches against casual players just by reading these patterns. Read the full psychology deep-dive →

You think you're random. You're not. Every human creates unconscious patterns in their choices -- and a Markov Chain can learn them.
