Role: solo designer: design direction, economy design, the burst quality bar, playtests. Built with: UE 5.8.2 Blueprint, online multiplayer (listen server), Chaos fracture, Claude Code. Timeline: Sep 6 – Oct 13, 2026. Status: approaching Feature Complete; Steam Deck build running.

| By the numbers

22 → 7 ms

Worst frame of the burst after a physics fix

150 ms

8-player sync holds at 150 ms lag and 3% packet loss

50 rounds

8-bot soak: total chips constant every round, so the economy is truly zero-sum

7.6 vs 13

Bands to pop a lime vs a gourd, measured over 96 rounds

| The design house

1. The room watches one object

Every tell is on the fruit (squash, creak, cracks, bands piling up); the UI only confirms.

2. Every band is a choice under pressure

Short turns, a small hand of special bands and a hidden burst point mean nobody is ever safe.

3. Losing is funny, not punishing

The economy is zero-sum, broke players get topped up, and nobody is eliminated mid-match. Virtual chips only: no buying, no cash-out, ever.

| Inside the design

The fun

The whole room stares at one fruit. Every snap is a bet against a hidden burst point, and the fruit itself tells you how close it is. The payoff is shared and loud: the pop, the splatter, and everyone who bet on the right band.

PARTY · ONLINE · STEAM DECK

Decision: tells without leaks

The burst point is hidden per round, but every visual tell is driven by a public tension value. Players read the fruit; nobody can read the answer.

SYSTEMS · FAIRNESS

Decision: fruit you can read, bots that play fair

Bigger fruit are tougher (lime 0.7× → gourd 1.25×) and you can see which fruit it is, so betting becomes a reading exercise. Bots take the same seats and inputs as humans and never read the hidden threshold, so a human can beat them by reading the same tells.

Proof: the burst quality bar

The pop is the whole payoff, so it got a quality bar: the burst’s worst frame went from 22 ms to 7 ms after a physics fix, in the packaged build.
