A fruit machine is provided with the usual drums (3) which can be spun to stop randomly with various symbol combinations showing on a win line (4). It further has a 'nudge' feature occasionally available by which each drum can be indexed forwards or backwards to bring different symbols onto the line. A separate panel indicator (8) has a column of symbols (9) for each drum, with means for illuminating the symbols in succession down each column. When a particular nudge feature is available the time allowed for nudging is determined by the preferably accelerating advance of the illumination through the associated column. The feature may be accompanied by a pulsing tone, increasing in frequency with the illumination advance.
