"Other" brackets are used to group together the more unlikely, high scores. These selections do NOT mean all home wins / draws / away wins.
"Other Home Win" covers all home win scores NOT listed such as 4-0, 4-1, 5-1, 5-3 etc. If the result of a match is 2-1, then ‘Other Home Win’ would be a losing selection as 2-1 is listed on the coupon as a separate selection.
Similarly "Other Away Win" covers all away win scores NOT listed on the coupon & "Other Draw" covers all draw scores NOT listed on the coupon such as 2-2, 3-3, 4-4 etc.
