Paper lotteries are slow to set up and easy to question. "Did you fold all the slips the same size?" With an online drawing tool, results are generated by an algorithm — no paper, no accusations, no setup.
This guide compares the main types of online lottery tools and explains which one to use for different situations.
What is an Online Lottery?
An online lottery uses a random number algorithm to select winners or assign outcomes, replacing physical draws like pulling names from a hat or spinning a physical wheel. The key property: no human can predict or manipulate the result before it happens.
With the right tool, online draws are actually more transparent than paper lotteries — everyone can watch the draw happen in real time.
Types of Online Drawing Tools
1. Amida Kuji (Ladder Lottery)
Assigns different outcomes to all participants simultaneously through a grid of vertical lines and horizontal rungs.
- Best for: Giving every participant a unique result at once (prizes, task assignments, team splits)
- Group size: Works best with 2–10 participants
- Highlight: Animated paths make the process visible and fair-feeling
2. Roulette Wheel
Spins through a list of options and lands on one at random.
- Best for: Picking one item from a list — first presenter, one prize winner, one restaurant
- Group size: Any size; visually clearest with 10 or fewer options
- Highlight: Spin animation builds suspense, great for live events
3. Random Number Generator
Generates random numbers in a specified range.
- Best for: Numbered ticket draws — assign everyone a number, then generate the winning number
- Group size: Scales to any size easily
- Highlight: Simple, fast, and easy to document

Practical Use Cases
Giveaways and Prize Draws
Put participant names in a roulette wheel and spin. For events where different people get different prizes, use Amida Kuji — enter participant names on one side and prize names on the other, and the grid matches them automatically.
Remote Team Task Assignment
Screen-share during a video call while running the draw. Everyone sees the result live, making it fully transparent. Paste the outcome in the chat as a record.
Classroom and Club Activities
Student committee assignments, sports team selection, or any situation where multiple roles need to be filled fairly. Amida Kuji with an animated reveal works especially well in classroom settings.
Social Media Giveaways
Compile your list of qualifying entrants, run a roulette or random number draw, and screen-record the selection. Posting the recording shows followers the process was unbiased — far more credible than simply announcing a winner.
Frequently Asked Questions
- Can the organizer cheat with an online drawing tool?
- Once names are entered and the draw runs, the outcome is determined by the algorithm — the organizer can't steer it. To maximize trust, show participants the full name list before spinning, and don't make any changes after participants can see the screen. Screen-recording the draw and sharing it afterward also helps.
- How do I prevent the same person from winning twice?
- Remove the winner from the list before drawing again. In roulette tools, simply delete the name and spin again. For Amida Kuji, regenerate with the winner removed. Most tools make this straightforward — just edit the list between draws.
- Do participants need to be in the same room?
- No. Browser-based tools work over video calls with screen sharing. The organizer runs the draw while everyone watches. This works equally well on Zoom, Google Meet, Teams, or any platform with screen share capability.
- Do I need an account to use these tools?
- For most free browser-based drawing tools, no account is needed. Open the tool, enter your data, run the draw. Works on mobile too, so you can use it on the spot without any setup.
