  "account": "Pyramid is the flagship game on a platform developed by the same team behind iCourt. In Pyramid, players join a live round with a stake in a non-purchasable in-game currency. As more players join a round within a short recording window, a shared multiplier grows with each new participant. Players can exit the round at any time and lock in the multiplier at that moment. If the recording window closes and not enough players join, the round collapses, and anyone still in the round loses their stake for that round. There are no deposits or real money involved; it's a purely tension-based mechanic.\n\nWhat made Pyramid the hardest synchronization problem on the platform compared to iCourt was the need to handle an unbounded number of concurrent actors all racing against a shared, ticking clock. The server had to accept or reject each JOIN/EXIT with a fresh, deduplicated nonce, recalculate every remaining player's live multiplier as new joins occurred, broadcast the authoritative state to every connected client, handle the recording-window countdown server-side only, and render client-side timers purely for rendering purposes.\n\nThe team used Socket.IO for socket communication, ran the server themselves instead of using a CDN build due to privacy concerns with browsers like Brave, and implemented Firebase / Firestore for wallet balances, player identities, and persistent stats. They also created a dedicated REVEAL_ENTRY sequencing system to reveal entries one at a time with a short stagger to create a dramatic visual effect. When a round collapses, every client receives a COLLAPSE event with the real numbers of how many joined, how many exited, and the final multiplier, providing transparency about why the round collapsed.\n\nThe team has already observed two distinct behaviors among users: some players play one round and leave regardless of the outcome, and at least one player forfeited mid-round rather than riding it out or exiting cleanly. These insights are valuable for refining the loss/collapse-screen experience and ensuring players understand the reasons behind their losses. Pyramid is currently free to play with no deposits or purchases, allowing users to experience the tension mechanic without any real money involvement.",
