Game proposal. Odd or Even. Multiplayer. Two players. Two devices

Create a multiplayer application "Odd or Even" to work on two devices.

A player will press a number from 0 to 3. An image of a hand will be displayed.
Then he will press an "Even" or "Odd" button.

That information will be sent to CloudDB.

Another player will perform the same actions on their device.

When both players have pressed their "Even" or "Odd" button, the result of the sum of those numbers will be displayed on both devices.
And it will be indicated if any have won or tied.


@Juan_Antonio I didn't quite get it.
Is it a contest or something?

It is simply an idea, a proposal, a challenge,... in case someone wants to do it.
