Why did my slip not count?

A slip only counts if it is sealed when the match starts. If you filled it in but never tapped "Seal my slip", it stayed a draft: it is not graded, it adds and subtracts no points and it is not on the table.

Other reasons

• You edited it and did not seal it again. Tapping "Edit" turns the slip back into a draft until you seal it again.
• You were not signed in. A slip cannot be sealed without an account.
• The match was not played. If a match is suspended or called off, its slips are void and cost nothing.

If you leave the match page with an unsealed draft, your browser warns you first.
