One ladder, one result per person
Each horizontal rung swaps two neighboring paths. Because same-row rungs never touch, every participant follows one unambiguous route to exactly one outcome.

Set up the draw
Add the same number of participants and outcomes, from 2 to 12. Each label must be unique.
Run a fair ladder draw in your browser
Enter people and outcomes, create a randomized ladder, and reveal paths one at a time or all together. The draw supports 2 to 12 entries.
Securely randomized
Ladderform uses the browser’s cryptographic random generator to build every new ladder. Drawing again creates a fresh arrangement without relying on Math.random.
Labels remain in this tab
Participant names, outcomes, the ladder, and revealed matches stay in browser memory. They are not uploaded, stored, analyzed, or placed in the URL. Closing or refreshing the tab clears them.
Clear and practical limits
Labels are limited to 40 characters and must be unique within each list. The 12-entry maximum keeps the diagram readable and the draw responsive on smaller screens.
