The Game:

This simple game uses the ESP-NOW protocol to transmit a basic set of data, including a random integer value and the health level of the broadcasting unit. It is designed as an oversimplified model of biological virus transmission.

Here's how it works:

  1. Broadcasting:

    • Each unit transmits data using the ESP-NOW protocol, which only covers a moderate distance.
    • Data includes a random integer value and the health level of the broadcasting unit.

  2. Game Mechanics:

    • When a device receives a broadcast message, it plays a game similar to the classic card game "War".
    • The broadcasting unit selects a random number within a set range.
    • The receiving unit, with a slight advantage, selects from a slightly larger range.
    • Health points are gained or lost based on the game's outcome, randomized within a set range.

  3. Infection Status:

    • If a device's health value is 0 or less, it is considered 'infected'.
    • Health values range from -100 to 100.
    • The OLED display and LED matrix show the health status. -100 health lights the grid red, while 100 health turns the LEDs green. 😎

  4. Scoring:

    • Points are assigned for specific events and increase continuously, allowing for comparison with other users at the event.
    • Devices powered on and actively playing the longest have the best chance for high scores.

Hacking:

The device uses a simple protocol and transmits a basic data structure. We encourage you to:

  • Sniff the Air: See what kinds of transmissions can affect game outcomes. Good luck!
  • Re-program After DEFCON: Pin numbers are listed inside the PCB. Code for the LEDs on the grid and ring will be provided in the Deepnetstore GitHub.
