Gamba

Try your luck with your skin coins. Gamba adds a machine to the shop where one coin can become two, turn into a better coin, or disappear entirely.

How to play

Find the machine against a wall in the shop, preferably near the secret rooms. Stand in front of its screen and press your normal Interact key (default E).

Gamba uses the last skin coin in your personal coin stack, just like the cosmetic machine. Watch your coin enter the slot, the handle pull it inside, and the screen reveal your result.

Default chances:

• 50% — Lose: the wagered coin is gone.
• 30% — Double: receive two coins of the same tier in total. One coin becomes two, not three.
• 20% — Upgrade: receive one coin of the next tier. An UltraRare coin returns two UltraRare coins instead.

Rewards go straight into your coin balance. The coins in the lower tray show what you won; you do not need to pick them up. Your bottom-right coin display updates when the screen reveals the result, so it does not spoil the outcome early.

Only in-game skin coins are used, never real money.

Installation and multiplayer

Install through Thunderstore Mod Manager with the listed BepInEx dependency. Everyone in the lobby needs Gamba 0.5.3. Only the player using the machine spends and receives coins.

The machine is placed automatically where a reachable wall and enough space are available. It keeps the cosmetic machine, doors and aisles clear. If no suitable spot fits, it will not force a machine into the room.

Keep the host connected until the result appears. Results are saved before the reveal; leaving during the animation does not cancel a completed wager. If a save warning appears, keep the game open until it clears.

Settings

Settings are in BepInEx/config/robin.repogamba.cfg:

• The host can adjust the lose, double and upgrade weights.
• Adjust the machine's audio volume or turn its sound off.
• Adjust the screen/sign brightness and sign flicker.
• Enable ReducedMotion for a still handle and coins, no reel cycling and steady lighting.

Compatibility

Developed against R.E.P.O. 0.4.4.3. Core interactions and saves were tested in solo and a private single-host lobby. The latest wallet-display and shortcut-removal changes passed build and focused code checks, but have not had a new gameplay test. A second real client and every mod combination have not been tested.
