{"game":"minesweeper","name":"Minesweeper","description":"The classic logic game: reveal every safe cell on a hidden minefield using the number clues, and flag the mines. Your first reveal is always safe.","kind":"finite","rules_html":"\n    <p>The board is a grid of hidden cells, some of which hide mines. Reveal a safe cell and it shows how many of its 8 neighbors (including diagonals) are mines. A cell with no neighboring mines shows <code>.</code> and automatically opens all its neighbors, so large empty areas flood open. Reveal a mine and you lose.</p>\n    <p><b>Coordinates:</b> always <b>row first, then column</b>, both numbered from 1. Row 1 is the top row and column 1 is the leftmost column. <code>reveal 3 5</code> opens the cell in row 3, column 5. The text board labels rows on both sides and columns above and below.</p>\n    <p><b>Your first reveal is always safe:</b> mines are placed after it, never on that cell or its neighbors.</p>\n    <p><b>Flags</b> mark cells you believe are mines. They protect a cell from <code>reveal</code> and are needed for <code>chord</code>: on a revealed number whose count of neighboring flags equals the number, <code>chord</code> reveals all its other hidden neighbors at once. If one of those flags is wrong, the chord hits a mine.</p>\n    <p><b>Text symbols:</b> <code>#</code> hidden, <code>F</code> flag, <code>.</code> revealed with no neighboring mines, <code>1</code>-<code>8</code> revealed with that many neighboring mines. After the game: <code>*</code> mine, <code>X</code> the mine that was revealed, <code>!</code> a flag on a safe cell.</p>\n    <p><b>You win</b> when every safe cell is revealed (flagging mines is optional).</p>\n    <p><b>Score:</b> timing doesn't matter. A win scores the difficulty's base points (beginner 100, intermediate 400, expert 1000) plus an efficiency bonus of up to 50% of base: <code>base × 0.5 × min(1, 3BV ÷ clicks)</code>. 3BV is the minimum number of reveal clicks the board needs without chording, and clicks are the <code>reveal</code> and <code>chord</code> commands that opened at least one cell (flags don't count). A loss or resignation scores partial credit: <code>base × 0.5 × safe cells revealed ÷ total safe cells</code>.</p>","commands":[{"syntax":"reveal <row> <col>","description":"Reveal a hidden cell.
