The new version of 'lotto' uses a roulette wheel to generate the numbers for checking against those marked on an entered card. The cards reflect the use of the wheel in that the number selection fields are marked with a roulette wheel pattern. Typically the card symbols have 37 numbers in an outer ring (2) and a selection of 5 is made by marking an 'X' in an inner ring area (3). The marked selection is readily machine read. An additional field (4) allows the sequence to be indicated.
