Leaderboard Merger

Leaderboard Merger is a standalone hardware device responsible for collecting leaderboard data from a defined set of arcade machines, merging those results into a single ranking, and presenting the combined leaderboard on its own display.

The device operates independently from the arcade machines and periodically synchronizes data according to the selected connection scenario.

Connection Scenarios

Leaderboard Merger supports two operating modes:

• Local
• Global

Each scenario defines how the device communicates with arcade machines, how the data is obtained, and how frequently the leaderboard is refreshed.

Local Scenario

In the local scenario, the Leaderboard Merger and all arcade machines must be connected to the same local wireless network (WLAN).

Key characteristics:

• No internet connection is required.
• All devices must be in the same WLAN.
• Data refresh interval is 5 seconds.
• This mode is recommended for on‑site installations such as arcades, bars, or live events.

Typical use cases:

• Single venue installations
• Event-based setups
• Temporary locations without internet access

Global Scenario

In the global scenario, the Leaderboard Merger and arcade machines communicate over the internet.

In this mode, the Leaderboard Merger requires a configuration file containing a list of machine serial numbers. Only machines listed in this file will be queried for leaderboard data. This allows precise control over which machines participate in the merged leaderboard (for example: machines belonging to a specific venue, region, or event).

Key characteristics:

• Each device connects to an internet‑enabled WLAN
• Devices do not need to be on the same local network
• Data is retrieved via a remote server
• Configuration file with machine serial numbers is required
• Data refresh interval is 60 seconds
• This mode is suitable for aggregating leaderboards from geographically distributed locations

Typical use cases:

• Chain locations
• Distributed tournaments
• Global or regional rankings

Settings

Configuration file

Notice: As of 2025-12-16, the configuration file can only be created and deployed by the producer. Operator-side configuration tools are still under development.

File Data/serials.json is required for operation in the Global scenario. It defines the list of arcade machine serial numbers whose leaderboard data will be collected and merged.

Example content of the file:

{
  "_version": 1,
  "serials": [
   "1111222233334444",
   "5555666677778888"
  ]
}

Access Point Mode

If no existing WLAN is available at the location, the Leaderboard Merger can be configured to create its own wireless access point.

In this setup:

• Leaderboard Merger acts as the Wi‑Fi access point
• Arcade machines connect directly to this network
• No external network infrastructure is required
