Block Party — a daily puzzle seeded by the chain

Games are how a lot of people first touch a chain. Memba's first game, Block Party, is a daily 2048 whose board is seeded by the chain — so everyone plays the same daily puzzle, and no one can reroll for an easier one.

What you get (product)

Play the Daily — a puzzle everyone shares that day — or Practice any time. There's a leaderboard for the daily. Crucially, you can play fully without connecting a wallet; connecting is optional and only matters when you want to put a score on the board. The game is designed to be the low-friction front door, not a wallet gate.

Under the hood (engineering scope)

The daily seed is derived from a chain value, so the board is deterministic and identical for every player that day. The move engine exists twice — once in TypeScript (the browser) and once in Go (the backend) — and the two are byte-identical, verified against shared test vectors. That parity is what lets the backend trust a client's replay: it can re-run the exact same engine and get the exact same result.

Because scoring is validated server-side (and, in the reward phase, gated per submission by a signature), the leaderboard is checked, not merely claimed — we don't call it "trustless," because it isn't; it's verified. The game ships dark behind VITE_ENABLE_GAME / BLOCKPARTY_ENABLED, and bounded integer casts in the engine are explicitly annotated so the security linter stays honest.

Block Party is the template: more wallet-optional, chain-seeded games are on the way, all playable first and connectable second.
