Solo System is also based on the selection box but only operates on Saturdays and bank holidays.

On Saturdays and Bank holidays go through the day's race cards and look for the selection boxes in the Racing post, with the exception of the principle meeting of the day and any major races at other meetings.

Ignore the top seven selections and pick out the selections that have been chosen as nap or next best by a journalist but have not been chosen at all by the others.

Although there should be more bets than in the selection box system there still won’t be many.
