HOW TO PLAY

Match every edge

  1. 1

    Start or load a puzzle.
    Choose New to generate a hard set or build your own, or load a saved prototype set or board.

  2. 2

    Click to cycle tiles.
    An empty square gets prototype 1. Each click advances to the next prototype; after the last one, it becomes empty. You can also drag a specific tile.

  3. 3

    Watch the touching colors.
    Red outlines show tiles with a mismatched neighbor.

  4. 4

    Correct a board change.
    Use Undo and Redo, or press Ctrl/Cmd+Z and Ctrl/Cmd+Y. Memo typing keeps the browser’s normal text undo.

  5. 5

    Enter competition mode.
    Under BOARD, choose “Load board”, then load a GLOBAL approved puzzle. Your time can enter its global leaderboard, and automatic solving is disabled.

  6. 6

    Text file values.
    Edges use numeric values from 1 through 7.
