Mapping

Rungs are random. Agree on rules before using for prizes or penalties.

When it helps

When you want to link people to prizes or penalties in a random-looking way without drawing on paper. Rungs stay hidden until you choose to reveal them.

Examples

Pick column and rung counts, type names and outcomes, reveal, then check the table—or tap a name for one colored path, or show all paths at once.

Notes

For high-stakes prizes, follow your official rules. This is a visual aid only.
