Arcade cabinets, from game code to bill acceptor.

Redplum Games sells skill game cabinets and redemption kiosks to operators across the US. We built the games, the locked-down Ubuntu kiosk they run on, the hardware integration and the ticket validator app that closes the loop.

Redplum Games cabinet lineup and redemption kiosk
The brief

Fun to play.
Impossible to tamper with.

A skill game cabinet sits in a public venue with cash inside. It has to be fun enough to play again, and secure enough that nobody can reach the operating system, change a payout or forge a ticket.

Operators also need machines that stay up without a technician on call: updates over USB or the network, and hardware that reports when something goes wrong.

What we built

The whole stack, one team.

01

24 skill games

Built in Unity in 3x3 and 5x3 formats, each in nudge and zero-chance versions, sold as five bundles.

02

Locked-down kiosk OS

Ubuntu with encrypted root and home directories. The cabinet boots straight into the game, with no desktop and no shell to reach.

03

Hardware integration

Custom IO APIs drive the USB bill acceptor, ticket printer, IO board and touch screen from inside the game.

04

Operator tools

Attract mode, leaderboards, an admin panel with live analytics, and game updates over USB or the network.

Secure Ticket Validator

Every ticket, checked in seconds.

Cabinets print encrypted QR tickets. The Redplum Secure Ticket Validator is the Android app venues use to redeem them: point the camera, and the app checks the ticket, flags anything already redeemed and records it against the right terminal.

  • Encrypted QR tickets that cannot be forged or reprinted.
  • Already-redeemed checks so a ticket pays out once.
  • Ticket history and registered terminals for every venue.
