Deposit amounts that work with players
Adding a 300 SEK quick-pick lifted lower-tier deposits by 18.7%, at the expense of the 500 SEK tier. We redesigned the amount grid around behaviour, tested smart defaults and built a fail-safe for Swish outages.

Context
The cashier is where intent becomes revenue. Swedish players deposit with Swish or Trustly, and the quick-pick amounts we show act as anchors: they shape how much people put in.
A 300 SEK option had been added to the grid. Deposits went up in count, but the data suggested players were trading down.
- increase in lower-tier deposits after the 300 SEK option was introduced
- 18.7%
- deposit share retained by the 500 SEK option after optimisation
- 12.5%
- conversion rate for the 150 SEK entry point among new users
- 4.1%
My role
I did the research and the UX and UI. I also changed the process for this project: the existing high-fidelity design system was proven, so we skipped low-fidelity wireframes, iterated directly in it, and put the time into experiment design instead.
Process

What the data said
- Cannibalisation of high-tier depositsThe 300 SEK option drew players away from the 500 SEK tier.
- A shift at the entry levelThe 300 SEK button also increased smaller deposits, such as 200 SEK, rather than only adding volume.
- Payment method changed the paceSwish, integrated in May 2023, made depositing much faster, so the preselected default needed rethinking.
- Different mental modelsPlayers see Swish as an express payment and Trustly as a more formal banking step.
- Dead ends at the cashierPreselecting Trustly automatically when Swish errors cut “cashier dead-ends”.
What we recommended
- Dynamic anchoringReplace the static default with a preselected amount based on each player’s deposit history.
- A/B test value gridsIn Frosmo, test a high-value grid with 1000 SEK preselected against the current low-value grid, measured on average deposit value.
- Quick-picks per payment methodTune the suggested amounts for Swish users to match its impulse-speed nature.
- Cleaner reportingExclude first deposits from general cashier analysis so recurring behaviour is measured accurately.
- Watch the fallbackTrack whether conversion drops when the system switches from Swish to Trustly.
What changed

- Remaining daily limit in viewThe deposit sheet shows a progress bar and how much of the daily deposit limit is left, right above the amount.
- Graceful degradationIf Swish fails, Trustly is preselected and the player continues. An outage becomes a detour instead of a support ticket.
- Clear withdrawalsOnce wagering is complete the withdrawal screen says so plainly and explains that money goes back to the account used for the last deposit.
Outcome
Success is measured on average deposit value and cashier conversion, while making sure the Swish-to-Trustly fail-safe keeps transactions flowing. The expected side effect is fewer “cashier not working” tickets.
