House of Diamonds / Queen's Castle

Full-cabinet view of a wood-rail electro-mechanical pinball machine photographed from the front, showing the entire playfield under glass plus the front coin door. The playfield is a bright yellow, blue and green 'space/rocket' layout crowded with mechanical targets and bumpers. At the top is an arched upper-playfield area with two large white bowl-shaped saucers, a mushroom-capped '1,000 POINTS' dome and a black round hole, flanked by cartoon rocket-ship bumpers and card-suit shields. Below sit two diamond-symbol drop targets and a row of ten numbered round targets (1 through 10) marked 'TARGET VALUE' at each end. Two yellow flippers sit low, with matching 'SPECIAL / BONUS BALL WHEN FLASHING' aprons and 'ADVANCE BONUS' and '3,000' and '500 POINTS' markings at each side. A dense field of small sunflower-like rosettes fills the green lower mid-field around a 'DOUBLE BONUS WHEN LIT' gate and a central rocket nose, with a yellow 'BONUS BALL' arch above the flippers. A white instruction card headed 'HOUSE OF DIAMONDS' sits on the apron. Colours are dominated by yellow, blue, red and green.

Full-colour backglass artwork in a medieval-fantasy painted style. Centre: a bearded king in a gold jewel-studded crown, red cloak and chainmail, holding an upright sword, his boots planted on a harlequin-diamond patterned floor. Over his left side hangs a large swallow-tailed banner reading HOUSE OF DIAMONDS in red-and-yellow block capitals on black, framed by a red-and-gold lozenge border, with three glowing diamond icons beneath. Upper left is a stone castle with turrets and a portcullis gate; before it a silver-armoured knight on a red horse with a white-and-red caparison holds a round white shield. Upper right a red-and-white striped market awning, and a grinning jester in yellow and red cap-and-bells costume leaning over the CREDIT panel. Right side shows a large grey cartoonish robot head with round eyes and a red triangular mouth. Four ornate gold-framed windows carry red LED score digits, and red diamond plaques numbered 1, 2, 3 and 4 mark the players. Lower left an ELECTRONIC plate on purple, framed by green laurel; bottom centre reads 1 TO 4 CAN PLAY above 1 2 3 4.

A rectangular backglass in a flat, brightly coloured cartoon style, framed by an ornate gold rococo scrollwork panel filling the upper left half. Six mechanical score reels sit inside a white window with black digit faces, reading '2,3 4 1,0 0 0', with a gold crown mounted directly above them. A jagged-edged green starburst in the centre carries the title in two lines of white rounded script with heavy black outline and drop shadow: 'QUEEN'S CASTLE'. Three figures: on the right a fair-skinned blonde princess in a small gold crown, wearing a blue gown over a white blouse with puffed sleeves and a magenta cloak, seated sideways on a green-upholstered gold-carved throne, chin resting on her hand, gazing left with a bored expression. On the left a white-haired bearded knight in a blue tunic, red-and-white striped sleeves and leggings, and a helmet, stands clasping an upright sword. Below him a grinning jester in a red-and-yellow fool's cap with bells, blue tunic and yellow collar, kneels holding a large white sheet of paper. The background is a stone castle interior: three pointed Gothic stained-glass windows at upper right in blue and purple, red and green diamond-tiled floor, and red jagged banners.
