Secret Santa exclusions - stop couples drawing each other
Secret Santa exclusions let you tell the generator which people should not be matched together, so couples, spouses, or family members who already buy gifts for each other can join the exchange without ending up as each other's Secret Santa. Tozi handles this automatically during the draw - the matching stays fully random within your rules, and no one (including the organizer) can see who drew whom.
Create a Secret SantaWhy exclusions matter for real-life groups
Most gift exchanges happen within groups where some people have existing gift-giving relationships. A married couple in a family exchange, two close siblings, or a pair of roommates in a friend group - these pairs already buy for each other and joining the Secret Santa is meant to add variety, not double up.
Without exclusions, pure random draws can and regularly do pair these people together. That wastes a match, defeats the point for those two participants, and requires an awkward re-draw that feels rigged even when it isn't. Setting exclusions before the draw solves this cleanly.
Common situations where exclusions are useful
Couples and spouses are the most common case - they buy for each other already, and a Secret Santa match between them just means spending the budget on something they would have bought anyway. Immediate family pairs (parent and child, two close siblings) often fall in the same category.
Office exchanges sometimes use exclusions for managers and direct reports, to keep the exchange feeling peer-level. Some organizers also exclude pairs from the same household who share finances, since a gift between them isn't really a surprise. Any pair the organizer knows shouldn't be matched can be added as an exclusion.
How Tozi handles the draw with exclusions
When you set up exclusions in Tozi, you mark specific pairs as restricted. During the draw, the algorithm works through a random assignment that satisfies every exclusion rule - each person draws someone they're allowed to draw, without being drawn back by that same person (no reciprocal matches).
If your exclusion list is very large relative to your group size, the algorithm will warn you before drawing because too many restrictions can make a valid assignment impossible. As a rule of thumb, exclusions work best when the excluded pairs make up less than half the group.
Matches stay secret - even from you
The draw in Tozi is designed so the organizer does not see who drew whom - only the individual participant sees their own assignment. This applies even when exclusions are in place. The couple you excluded from matching each other will not know you set that exclusion, and they will not know who drew their name.
If someone asks you who has them, you genuinely don't know - which is the point. The secrecy is structural, not just a promise. Exclusions are a setup option for the organizer, not a visible part of the exchange for participants.
Frequently asked questions
How do I add exclusions in Tozi?
When setting up your exchange, there is an exclusions step where you select pairs of participants who should not draw each other. You can add as many pairs as you need before the draw. Exclusions can also be edited after participants have joined, as long as names have not been drawn yet.
Will participants know I set an exclusion for them?
No. Exclusions are only visible to the organizer during setup. Participants see their assignment but have no way to tell whether any exclusions were applied to the draw.
What if my exclusion list makes a valid draw impossible?
Tozi will alert you before drawing if your exclusions cannot be satisfied with the current group. This can happen in small groups with many exclusions. The fix is usually to reduce exclusions or add more participants.
Do exclusions work both ways automatically?
Yes. If you exclude Person A from drawing Person B, Person B also cannot draw Person A. All exclusions are two-way - you only need to add each pair once.
