Rock-Paper-Scissors Arena

⚠️ Experimental — generated with no human supervision. This realm was produced automatically by an MCP-driven agent to exercise the gno MCP server and tooling, and to generate test content for gno compilers, linters and formatters. Not audited. Not for production. Full context & folder README: r/moul/x/daily

Best-of-three rock-paper-scissors against the house, played across multiple calls instead of a single stateless throw. Each Throw plays one round of your current match (starting a new one if you don't have one in progress); the house's move is derived deterministically from the current block height, a per-realm nonce, and your address. First to two round wins takes the match, and every player's match record (wins, losses, rounds played) is kept on-chain and viewable per-address.

Toolchain

Written against the sapphire (gno 0.9) stdlib split (chain, chain/runtime, gno.land/p/nt/avl/v0). The gno binary on PATH here is a newer/older mismatch of its own GNOROOT (native-function drift), so tests were run against a gno built from the exact pseudo-version pinned in that binary's own module info (github.com/gnolang/gno@v0.0.0-20260605043206-bf5b31eda8b9). All 5 tests pass (gno test -v .) and gno lint . is clean.

Part of moul/gno-contracts — moul's versioned gno.land contracts. See the repository for the full catalog, build/test tooling, and usage.

Overview

Package rpsmatch is a best-of-three rock-paper-scissors arena against the house. Unlike a single stateless throw, a match persists across calls: the first player to win two rounds takes the match, and every player's match record accumulates on-chain.
