Neon Nights

Real-money gaming has an unforgiving property: the game is the easy part, and the money boundary is where everything actually goes wrong. Networks drop mid-bet, aggregators retry, rollbacks arrive for rounds that already settled. If the accounting is not provably correct, the operator eats the difference.

So I built the whole thing from nothing — game engine, server, and a deliberately hostile fake wallet whose entire job is to break it: dropping responses, duplicating callbacks, settling out of order, reversing what the server believes is final. You cannot prove fault tolerance by hoping, and you do not get to make a real counterparty misbehave on demand.

It is playable with play money. A demonstrator rather than a licensed operation — no real money moves through it and it has not been certified.
