Royal One Ball

The Royal One Ball is a single-player, solid-state electronic bingo machine manufactured in 1997 by Willy Michiels of Belgium, under the trade name WIMI Games. As a Belgian-made bingo-style machine from the late 1990s, it was produced well outside the American and Japanese manufacturers that dominated pinball and bingo-machine production at the time, making it a curiosity for collectors interested in unusual regional manufacturers.

Detailed information about the Royal One Ball's specific layout, theme, and rules has not been documented. As with other bingo machines, its solid-state electronics likely governed scoring and payout functions rather than the flipper-based objectives found in standard pinball games.

Little is known about Willy Michiels or WIMI Games beyond a small number of machines bearing the WIMI Games name, leaving many questions unanswered about their role in the late-1990s European pinball and bingo-machine market.
