+  PACHINKO — a rectangle of pins. Pick your drop.
+
+  play pachinko              Take the single seat.
+  bet 10                     Commit 10 credits and reveal the board.
+  5 / drop 5                 Choose top slot 5 and drop the ball.
+  bet / rebet                Repeat your last wager and deal a new board.
+  table                      Show a blank board and the pay table.
+  stop                       Leave once no ball is in flight.
+
+  Every bet deals a fresh board of eight pockets and shows it before you
+  choose. Seven pockets are filler prizes drawn from 0.1x to 1.5x, mostly
+  0.5x and below, so the board is always busy. The eighth is a guaranteed
+  premium above 1.5x: usually 1.7x or 2x, occasionally 5x or 10x, and
+  about one board in 900 carries the 100x jackpot. Multipliers at or above
+  2x are whole numbers; below 2x they move in 0.1x steps. A DOUBLE appears
+  on about one board in twenty.
+
+  Filler prizes always return something, so a board is never a wall of
+  zeroes. Small fractions (0.1x, 0.5x) are the common texture; the
+  guaranteed premium is the reason to aim carefully.
+
+  Eight numbered top slots crown the board. A drop is 20 fair 50:50
+  bounces; the side walls reflect the ball, so the distribution is widest
+  in the middle and piles up against the walls. Because you see the board
+  first, the best slot moves from board to board. The pins stagger from
+  row to row, so even a ball that holds its lane visibly weaves between
+  them.
+
+  DOUBLE doubles EVERY prize on the board and drops the ball again for
+  free from any slot. The DOUBLE space stays where it is, so the doubling
+  can chain without limit: 2x becomes 4x, 8x, 16x... for as long as you
+  keep landing on it. The board grows hotter and brighter with each hit.
+
+  Multipliers INCLUDE your stake: 0.1x returns a tenth, 0.5x returns half,
+  2x returns double, and the 100x jackpot returns one hundred times
+  (before any DOUBLE).
+
+  Return is measured for a player who always chooses the best top slot:
+  exactly 100% — the house makes its money on slot choice, not on the
+  board. Dropping from a uniformly random slot returns about 80%. The table
+  command shows a blank board and the pay table; a House Edge instrument
+  reveals the exact odds. Fractional credits round without bias so the
+  average holds even for one-credit bets.
+
+  You cannot leave or re-bet mid-board. Shutdown refunds a committed
+  board; disconnecting forfeits an unfinished drop. A payout that cannot
+  be persisted keeps its stake pending for recovery rather than claiming
+  a paid win. Returns that would overflow the economy are capped.
