Declaring competition categories
Name, type, fee, capacity, skill rating range, check-in time — and the two things you cannot change once someone has registered.
Updated 9/27/2026
Manage → Settings → Categories. With no categories nobody can register — this has to be finished before you publish.
Each category is its own competition: its own groups, its own bracket, its own prizes.
The fields of a category
Category name
For example «Men's Doubles 4.0». Include both the format and the level so players pick the right one.
Category type
Singles · Doubles · Mixed doubles · Team. This decides how many players per team.
Registration fee
Charged per TEAM, not per person. Set it to 0 if it is free.
Maximum teams
Capacity. Leave it blank for no limit.
Minimum / maximum skill rating
The allowed rating range on the 0–10 scale. Leave it blank for no limit.
Playing date, start time, check-in time
Declared per category — several categories in one tournament often run at different times.
Category Zalo group
A separate group invite link. Only APPROVED athletes can see this link.
Two things lock once there are registrations
The category type can no longer be changed, because changing the type changes how many players a team has — teams that already registered would have the wrong roster size. And a category that has registrations or matches cannot be deleted; if you want to stop taking entries, close registration instead of deleting.
The rating range decides who can enter
The skill rating blocks at both ends. Anyone below the minimum or above the maximum cannot register into this category.
The maximum box matters more than it looks: leaving it blank means you are declaring the category open to any level, and afterwards you cannot reject an entry on the grounds that «the rating does not fit». A level-restricted category has to declare its ceiling from the start.
«Open scoring» — a switch per category
Inside the Categories group there is an «Open scoring» line. While it is off, referees cannot start matches or enter scores for that category, even with all the right permissions. Turn it on when the category goes live, off when its turn has not come.
Frequently asked questions
Is the registration fee per person or per team?
Per team. A doubles category declaring 500,000₫ means the pair together pays 500,000₫, not each player.
I declared the wrong category type and people have already registered?
It cannot be changed any more. The only way is to create a new category with the right type, tell the registered teams to move across, then refund and close the old category.
A referee reports they cannot start a match even though it is time?
Check «Open scoring» for that category. This is the most common cause — the referee's permissions are fine, the category simply has not been opened.
The maximum number of teams is reached but people can still register?
Check whether the entries being counted are approved ones. Capacity counts valid entries; a rejected or cancelled entry gives its place back.
