🧠 Memory Match

⚠️ 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

A concentration game on a 4x4 grid of 8 emoji pairs. The board is shuffled deterministically from the current block height (there is no on-chain RNG), so every NewGame produces a reproducible layout for a given height. Flip tiles two at a time: matching pairs stay face-up, mismatches flip back on your next move. The realm tracks your move count and matched pairs and reports the solved state.

Realm path: gno.land/r/REPLACE_ADDR/memory

How to play

• Flip(index int) — reveal the tile at index (0–15, row-major). The first reveal starts an attempt; the second completes a move. Matching faces stay up; a mismatch shows both tiles until your next Flip clears them.
• NewGame() — reshuffle the board using the current block height as the seed.
• Render(path) — renders the grid (❓ hidden, emoji revealed/matched), the move count, matched-pair count, and whether the game is solved.

Example calls

# start a fresh, height-seeded board
NewGame()

# reveal cell 0, then cell 5
Flip(0)
Flip(5)

# view the board
gnokey query vm/qrender --data "gno.land/r/REPLACE_ADDR/memory:"

Solve all 8 pairs to win; the render then shows your total move count.
