Connect Four

⚠️ 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 two-player Connect Four realm on a 7-wide × 6-tall board. The game creator plays 🔴 and moves first; the named opponent plays 🟡. Drop enforces turn order by caller, rejects full and out-of-range columns, and detects a horizontal, vertical, or diagonal 4-in-a-row (or a draw). Render draws the board with 🔴🟡· and shows whose turn it is or who won.

Realm path: gno.land/r/REPLACE_ADDR/connect4

Example calls

# create a game against another address (you are 🔴, returns the game id)
NewGame(g1zabc...opponent)   # -> 1

# drop discs into columns 0-6 (turns alternate, enforced by caller)
Drop(1, 3)   # 🔴 drops in column 3
Drop(1, 3)   # 🟡 drops in column 3 (called from opponent's key)

# view state
render:            # lists all games
render:1           # shows board for game 1
