Clean baseline + repeatability
Complete three Clean runs on the same setup to see repeatability.
Transform one five-letter word into another by changing exactly one letter per rung. Every puzzle ships with a graph-verified par against the same 8,636-word validation lexicon.
Ready. Start the run, then build a valid one-letter route.
Opening live graph guidance marks the current run Assisted. Post-game analysis is safe because the puzzle is already over.
Complete three Clean runs on the same setup to see repeatability.
Finish a ladder to see every rung’s exact remaining distance, detours and one verified shortest route.
Route Lab is separate from full-run Clean records.
A date-stable pair from the 2,048-pair Atlas. The linear 2,048-day cycle does not repeat a pair index within a normal calendar year.
One ladder for clean baseline and par chasing.
Three back-to-back endpoint pairs give more stable route evidence than a single lucky solve.
Solve as many ladders as possible in three minutes. Time adds pressure; par and validity rules do not change.
Pairs with detours, hints, reveals or skips enter a local queue. Three Clean near-par solves retire them.
Live Hint or Pace Coach means Assisted. Restoring an interrupted run means Review. Post-game graph evidence is safe.
Par, shortest paths and Route Lab truth come from the bundled 8,636-word graph and 2,048-pair Atlas. We do not claim that every bridge word is equally common, or that local scores represent a population percentile.
