## Request
Enigma Secret Contracts enable dApps to compute over encrypted data. One simple use-case for this is rock, paper, scissors, using Enigma to keep player choices secret until the end of each round (instead of a commit-reveal scheme).
## Solution Description
This solution should enable player A to create a new game by selecting “rock, paper, or scissors” via a visual interface, encrypt and submit the player’s choice to a secret contract, and then enable player B to select the active game, and submit the second player’s choice to the secret contract. The secret contract logic should decrypt the selections, select the winner according to the rules of rock, paper, scissors (rock beats scissors, scissors beats paper, and paper beats rock). The winning player’s address should be returned to both players.
## This will involve:
Writing an Enigma-JS interface that enables a player to start or join a game, make their move, and submits these moves encrypted to the secret contract.
Writing a secret contract that receives player addresses and moves, compares them according to the logic of rock, paper, scissors, and returns the winner.
## Success
A working application, which should have a simple React-based UI (or similar), enable the solution, and handle failure (i.e., displays a meaningful message when improperly formatted data is submitted). Two users should be able to play one another via the UI.
## Bounty Selection
For this first bounty round, the process works as follows:
1. Developer / team submits a **“pre-submission for approval”** for a bounty
2. Enigma reviews submissions, and selects an applicant (we don’t have a firm timeline for this, but hope to work quickly)
3. Applicant completes the task satisfactorily and receives the bounty
If the task is not completed, or applicant is unable to continue work in a timely manner, Enigma will select another applicant.
