Make group decisions with a clear 3D ladder draw. Supports 2–50 participants, saved history, and reruns with no account required. Amidamaru is a 3D ladder-draw app for making fair selections and assignments with groups of 2 to 50 people. KEY FEATURES • Supports 2–50 participants • Choose a fixed number of winners or assign numbered outcomes • Run everyone at once, from left to right, or choose each starting point • Follow every route with a clear, animated 3D presentation • Pause, resume, skip, or replay the presentation • Save completed draws automatically on your device • Run another draw with the same or adjusted settings The result is fixed before the 3D presentation begins. Pausing, skipping, or replaying the presentation never changes the outcome. No account is required. Participant names and draw results stay on your device and are not sent to the developer's server. The app is free to use and includes ads. A one-time Amidamaru Premium purchase removes all ads. Purchasing Premium never changes the draw, odds, or available outcomes. Use Amidamaru to assign turns, divide responsibilities, choose winners, or make group decisions at events and parties.
