Double or Nothing

🎰 Double or Nothing

Gamble ANYTHING. One slot machine, one rule: 50% you double it, 50% it’s gone.
Then you decide: double again… or cash out?

What can you bet?

How it works

1. Craft the machine from 8 cobblestone around a lever. You can start gambling on day one.
2. Pick your stake and pull the lever: LET’S GO GAMBLING!
3. The reel spins and crawls to a stop, often right on the edge between x2 and x0.
4. Won? DOUBLE (x4) risks everything again. Cash out and the machine sprays your winnings at you.

Closing the machine mid-streak counts as cashing out, so nothing is ever lost to a misclick or a disconnect.

Made for moments

• Reel that slows down and just makes it… or just doesn’t
• Marquee lights, lever animation, screen shake and red flashes on a BUST
• Jackpot pop-up from a 3-win streak on
• Item fountain when you cash out
• Losing your last heart gives its own death message: "Steve gambled away their last heart"
• A totem of undying saves you from bankruptcy (you keep playing on 1 heart)

Multiplayer / SMP

• Big wins, big losses and every ALL IN are announced in chat
• Everyone nearby hears and sees your wins and losses
• All rolls happen on the server. The client only sends button presses.

Config

No real money. No microtransactions. Just pain.
