Slot Machine

Slot Machine for AWTRIX NG (Ulanzi TC002)

Version 1.0 · by Hank_the_Tank / Claude · for the 52×16 panel of the Ulanzi TC002

A classic Las Vegas one-armed bandit for your clock: three spinning reels, a lever you can actually pull with the gamepad stick, flashing lights and synthesizer sound effects. It runs on demand, so you start it when you feel lucky, and it stays out of the normal app rotation.

Features

• Three reels, six symbols. Cherry, lemon, bell, BAR, diamond and the red 7, all drawn in code, so there are no icons to install.
• Real reel motion. The reels roll downwards, stop one after the other from left to right and bounce as they land.
• Suspense. When the first two reels match, the third one spins almost a second longer.
• A lever you can pull. On the gamepad, pull the right stick down and let go. The lever on the display follows your stick.
• Winning lights.
  • Any win turns the frame into a rainbow and flashes the amount in green.
  • The credits count up coin by coin.
  • Three diamonds or three 7s set off a full-screen fireworks show with BIG WIN or JACKPOT.
• Synthesizer sounds, created live by the TC002, no MP3 files needed:
  • lever pull
  • ticking reels
  • a clunk when each reel stops
  • a win jingle and coins
  • a jackpot fanfare with drums
  • a "wah-wah" when you lose
• Bet 1 to 3 per spin. The payout is multiplied by the bet.
• Auto-spin for lazy high rollers.
• Credits are saved. They survive a reboot. When you go broke, the machine flashes a red 0 and refills your credits after a moment.

Requirements

• An Ulanzi TC002 running AWTRIX NG. The layout is written for the 52×16 panel, and the script uses the TC002's gamepad module.
• Optional: a Bluetooth gamepad paired under System → Gamepad. Without one, the clock's buttons work too.
• Sound switched on in the clock's settings to hear the effects.

Installation

1. Open the AWTRIX NG web interface: the clock's IP address, or http://awtrixng-xxxxxx.local.
2. Go to the Scripts tab and create a new script called SlotMachine.
3. Paste the contents of SlotMachine.ax and press Save.
4. On the clock: hold the middle button, choose Scripts, then Slot Machine.

If the panel shows a red ERR:, the error message is shown next to the script in the Scripts tab. Please include it in your feedback.

Controls

Paytable

The middle row is the pay line. Payouts are multiplied by the bet.

Each reel carries 20 symbols: 5 cherries, 4 lemons, 4 bells, 3 BARs, 2 diamonds and 2 sevens. About one spin in six wins something, and 7-7-7 lands about once in 1,000 spins. As in Las Vegas, the house wins in the long run.

Settings

All settings are on the Apps tab, behind the gear on the Slot Machine row. Saving restarts the game.

The credits are capped at 999, the house limit.

Feedback

This is the first release. Useful feedback:

• The panel shows ERR:: the error text from the Scripts tab.
• A sound is too loud, too quiet or too shrill: which one it is.
• Ideas: more pay lines, new symbols or a different paytable.

Credits

• Game: Hank_the_Tank, with help from Claude.
