Overview
A new screen in Entain's internal admin tool that shows support agents what happened in a customer's casino session.
The problem. Agents could see a customer's sports bets and payments, but not what they did on Black Rush, Entain's online casino.
What I did. As the only designer, I designed the Game Activity screen and six supporting screens in about four weeks, reusing existing patterns.
The outcome. One screen shows play grouped into sessions, each payout split by type of money, and filters for casino, poker and bingo. Agents no longer need developers to look things up.
Problem & goal
Agents couldn't see casino activity.
A blind spot for support teams
Cerberus is the internal tool Entain's support, trading and risk teams use to manage customers across Ladbrokes, Neds, TAB NZ and Betcha. When Black Rush, Entain's online casino and bingo product, joined, agents couldn't see what customers did while playing.
Activity wasn't grouped
Every spin and hand appeared in one long list, with no link to a game or session.
Payouts didn't show their source
A payout can mix cash, bonus cash and free spins. Only the total was shown, so agents had to ask developers.
Casino, poker and bingo looked the same
Everything was labelled "Casino", so agents had to read game names to tell them apart.
Goal: one place for agents to see what happened in a casino session, organised, easy to filter, and showing each type of money used.
This was part of a larger rollout that also included VIP settings and casino risk review (see Other designs below). This case study focuses on Game Activity, the most complex screen.
The challenge
Why it wasn't a simple copy of existing screens.
Three problems to solve
Reusing the existing layout saved time, but three design problems still needed solving.
What counts as a "session"?
Slots are played spin by spin. Blackjack can last hours at one table. We had to define a session before grouping anything.
Where should casino activity go?
Deposits and withdrawals work differently from casino play and have different data, so casino got its own section.
Keep agents fast
Agents work quickly using keyboard shortcuts. Spacious layouts would have slowed them down, so the screen stays compact.
Role & team
Only designer, many stakeholders.
Keeping everyone aligned
I was the only product designer on the project, planned for three to four weeks.
- Open questions were tracked on a shared board, not in private messages
- Before the program lead's two-week leave, I ran a review with the product manager and technical expert to keep key work moving
Game Activity
Game Activity: the main screen.
Shaped by feedback
This screen had the most feedback rounds, with the product manager, the technical expert and a casino stakeholder. Three decisions shaped it.
Getting the columns right
The first version showed date, game, amount bet and amount won. Feedback added total stake, total win, multiplier and game provider, plus a Game Class field to filter casino, poker and bingo.

A session is one game played continuously until the customer takes a break. The same rule works for a three-hour blackjack session and a five-minute slots session.
Click to enlargeA dedicated section, with clear payouts
Casino activity has its own section instead of sharing the transactions list. A detail panel splits each payout into cash, bonus cash and free spins.

Other screens I designed.
Six supporting screens
Six more screens, each solving a day-to-day or regulatory problem found during research.
Outcome
The outcome.
Time spent on what was new
Existing layouts, tables and pop-ups were reused, so design time went into what was new: sessions, payout breakdowns and casino filters.
Agents can now open one screen and see what a customer staked, what they won, and where the money came from.
Reflections
What I learned.
Plan for unusual cases early
The blackjack question came up after the first designs. Next time I'll involve the risk and trading teams before sketching.
Design for reuse
Keeping the VIP screens free of brand names cost little and means other products can reuse them.
Clear scope makes speed possible
Four weeks worked because we were strict about what was new, and focused design time there.
