- Group names are hidden
- Every group is on the board. Click a group (or press its number), then click the bank buttons that belong to it.
- When a group is full the next open one takes over. A wrong pick stays in the bank: it belongs somewhere else.
- Only the size of each group is shown. Work out which set has that many members.
- Pause whenever you like (Esc). The board hides while the clock is stopped.
Fill each hidden group with the items that belong together. The groups and the bank appear when you start.
About this quiz
Every group is a list Ribbia has already checked for one of its other quizzes. The 28 bank buttons are dealt from those lists, and a name that appears on two of them is never used.
- All groups are on the board at once: fill them in any order.
- A wrong pick fills one of that group's slots with a cross. The item stays in the bank, because it belongs to another group.
- A hidden group shows its name once all its slots are used.
