Undi: Spin the Wheel & Raffle

Undi is the wheel you can trust in front of a crowd. Paste any list, spin a real wheel, and prove the draw was clean. Use it for classrooms, giveaways, office parties, game nights and every small decision in between.

A WHEEL THAT FEELS REAL
• Brass rim, marquee bulbs and a pointer that clicks on every peg
• Your swipe sets the speed, the turns and even the direction
• Set the duration from 3 to 30 seconds and the wheel keeps to it
• The name under the pointer stays large and readable for the whole spin
• A proper winner reveal with confetti and fanfare

PASTE ANYTHING
• Copy a list from anywhere and paste it: names, comma lists, spreadsheet columns, numbered lists
• Up to 5,000 entries on a wheel, and as many wheels as you like
• Write "Name x3" to give someone three tickets, or size any slice by hand
• Find and remove duplicates in one tap
• Import TXT and CSV files

RAFFLES DONE PROPERLY
• Winners leave the wheel, so nobody wins twice
• Set up prizes and reserves, then draw them in order
• Let Auto-draw run the whole raffle hands-free
• Undo the last draw, or reset and start again
• Share a Draw Receipt with date, time, winners and a list fingerprint, so anyone can check the list did not change
• Export results to CSV

TAKE TURNS OVER DAYS
• Rotation mode gives everyone exactly one win per cycle and remembers who has gone, even days later
• Made for classroom helpers, chores, shifts and rotating groups such as arisan
• Names only: Undi never handles money
