Exclusions, honored in both directions
Most name-draw tools treat “don’t pair these two” as a suggestion. MerryShuffle treats it as a constraint the draw must satisfy — or the draw doesn’t happen.
How it works
- You mark a pair (say, two partners). The draw engine then never assigns either one to the other.
- Self-draws are impossible by construction — a valid draw is always a strict one-to-one assignment with no fixed points.
- If the exclusions are too tight to admit any valid draw — say, two people who may each only give to the same third person — the tool tells you plainly instead of quietly bending a rule or hanging.
Exclusions are visible only to you, the organizer. Participants see their link and nothing else.
The precise guarantees are spelled out on the rules page.
