## Overview

Play confidential Rock Paper Scissors using Private Ephemeral Rollups. Each move lives in a private TEE account that neither the opponent nor the RPC can read — the winner is revealed automatically the instant the last choice lands, and either player can start a rematch that reuses the same accounts with no new rent.

The example includes a web app with a solo mode against a robot and a two-player mode where a friend joins via link or QR code.
