Fishbowl vs QR game: the arithmetic behind up to 20x more contacts
A business-card fishbowl collects a card only from the visitors who choose to dig one out, while a QR game asks every visitor who scans for a name and email before a 60-second game starts. The BoothBuzz page puts the gap at up to 20x more contacts, and this post works through the arithmetic with placeholder inputs, shows what 20x would take, and explains why it is the page's best case and not a promise.
What "up to 20x" means, and what it does not
The 20x figure is a ratio: contacts from a 60-second game divided by contacts from a passive business-card bowl, counted over the same stand. The page's own footnote says it compares a 60-second game with the typical conversion of a passive business-card bowl at a 3 m stand, and that it is a target and not a guarantee.
Read it as the best case the page claims for a 60-second game against a passive bowl at a 3 m stand: not a promise and not something to plan on. The ratio grows as fewer people use the bowl, so a high figure can say as much about the bowl as about the game.
This post quotes no results from real events. Every number in the worked example is an assumption for you to replace with your own counts.
The four methods side by side
Each method asks something different of the visitor and leaves you with something different.
| Method | Visitor effort | What you get | Consent record | Follow-up quality |
|---|---|---|---|---|
| Business-card fishbowl | Dig out a card and drop it in | A bowl of cards to type up by hand | None | A name and an email at best, with nothing about why the visitor stopped |
| Clipboard | Queue, then write name and email on paper | Paper to type up, where emails are often misspelt and writing can be illegible | None, and no marketing opt-in | The same as the bowl, if you can read the writing |
| Badge scanner | None from the visitor, which is why they walk past | Badge data only, in limited fields, under a licence per show | Check the organiser's terms in your exhibitor manual | Only the badge fields, with nothing the visitor chose to tell you |
| BoothBuzz | Scan the QR, type name and email, play 60 seconds, chase a prize | A spreadsheet of leads in Excel, CSV or PDF | A record per lead (text version shown, timestamp, device) and a separate opt-in that is never pre-ticked | Rank, score and timestamp, so the first line is the visitor's own score |
How a QR game visit runs
A camera scan of the QR takes about 3 seconds. The start screen then carries your logo, the prize on offer and a Play button. Before the game begins, the visitor types a name, email address, mobile number and company, answers whatever questions you added, and ticks the consent box. The game lasts 60 seconds, the result lands on a leaderboard shown on a stand TV, and ten people can play at once.
You choose between Gem Rush, a match-3 game scored on points, and Flip Match, a memory-pairs game scored on time. The games section shows both.
A worked example with placeholder inputs
This example is illustrative. The inputs are round assumptions, not results, and not measurements from any event. Replace each one with your own count before you draw a conclusion.
- Stand: one 3 by 3 stand over 3 show days
- Busy hours: 5 per day
- Stops: 20 per busy hour (a stop is a visitor who slows down at the edge of your stand)
- Bowl: 1 stop in 20 drops a card
- Game: 1 stop in 5 ends in a scan and a play
The working: 3 days × 5 busy hours × 20 stops = 300 stops. The bowl takes 1 in 20, so 300 ÷ 20 = 15 cards. The game takes 1 in 5, so 300 ÷ 5 = 60 plays. Then 60 ÷ 15 = 4, so these inputs give 4x, not 20x.
What would 20x take? Keep the 60 plays and the bowl would have to collect 3 cards, because 60 ÷ 3 = 20. Three cards from 300 stops is 1 in 100. That is what a 20x result would need: a bowl that almost nobody uses, beside a game that one stop in five plays. Treat it as the best case.
The chart plots the same placeholders per day: 100 stops, so 5 cards from the bowl and 20 plays from the game. It is illustrative only. Clipboard and badge scanner are not charted, because their results depend on the show.
To use your own numbers, count stops for one busy hour on day one, count the cards in the bowl at close, and divide. For cost, the game is AED 300 per exhibition day and AED 900 for a three-day show, with no set-up fee, licence or per-lead fee: divide AED 900 by the contacts you get. The lead capture cost breakdown sets that against the other options.
What the CEIR figures add
Trade show gamification guides quote CEIR figures of +40% lead generation lift and +42% longer dwell time for gamified stands. We are repeating them as quoted. We did not measure them, and they describe gamified stands in general, not BoothBuzz.
They are a different comparison from the 20x figure, so do not add the two or multiply them. Dwell time matters for a plain reason: a visitor who plays a 60-second game is likely to stay at your stand for those 60 seconds, which gives your staff a window to start a conversation.
A card in a bowl is a dead contact
At many stands the first words go from a staff member to a stranger who did not ask for them, and the stranger often decides on the spot whether to stop. A card in a bowl leaves that untouched: the visitor may drop it and walk on, and a week later you write to a name nobody at the stand spoke to.
A game reverses the sequence. Before anyone speaks to the visitor, the visitor has typed a real name and email, which is the price of a turn, so your staff member can open with the visitor's own score. A leaderboard on the TV then does three things that a paper form cannot. It gives visitors a reason to come back and defend a rank. It gives them a reason to fetch a colleague so that there is someone to beat. And it gives the prize draw a public moment, with you as host of a crowd and not a seller behind a counter. The live leaderboard guide goes through those three effects.
Every lead also arrives with a timestamp of when the visitor was at your stand, so the follow-up email can name the time and the score.
What changes for your staff
With a bowl, staff ask a question that invites a no: "Would you like to leave a card?" With a game, staff have a first line that is already about the visitor.
These opening lines are templates, not quotes from real people. Replace the rank, name and time with what your TV shows. The time suits Flip Match, which ranks on time; for Gem Rush, swap in the points score instead.
To a visitor who has just finished: "You are 4th, and the top time is 36 seconds. Do you want another go?"
To a visitor who played earlier: "You were 4th this morning, and someone has passed you. The board is still open."
To a visitor with a colleague: "Your colleague is ahead of you on the board. Scan the code and see if you can pass them."
Before the prize draw: "The draw is at the time on the start screen. Stay for it, and we will call the top three on the TV."
Brief your team on one rule: read the board before you speak. How BoothBuzz works lists every step from order to spreadsheet.
FAQ
How many more contacts does a QR game get than a business card fishbowl?
Up to 20x is the best case the BoothBuzz page claims, and its footnote calls it a target and not a guarantee. The worked example above gives 4x from placeholder inputs, so run the same arithmetic with your own stop counts.
Is a business card fishbowl still worth putting on a trade show stand?
It can sit beside a game for visitors who will not scan. It gives you a card with no consent record and no context, and the cards have to be typed up by hand.
What does a visitor have to do to play a QR game at a stand?
A camera scan takes about 3 seconds and opens the game in the phone browser, so there is no app to download. The visitor fills in contact details, ticks the consent box and plays for 60 seconds.
Does a QR game record consent when a fishbowl does not?
Yes. Each BoothBuzz lead is saved with the version of the consent text the visitor saw, the time and the device, and marketing opt-in is a separate tick box that starts empty. A card in a bowl has no such record. This is practical guidance, not legal advice: before the show, find out where the data is hosted and state that location in your privacy notice.
Run the numbers above against the pricing, then reserve Gem Rush or Flip Match for your stand.
