On my phone (Pixel 😎 you can see the top three cards however, when it starts slowing down and more people need one number you can't see any or you can see the top row. It leaves you having no idea whatsoever what you need. It's the same on a Chromebook too
It also doesn't put them in order sometimes and it doesn't highlight when you need three to go, two to go etc.
You are basically blind on your own cards until you win, it is really not good enough. Half the time it doesn't even say what number I need.
Why don't you put together a panel and ask your customers what they think? It seems designed by people who don't play the game and have no idea what people want to see. Generally speaking I would say bingo players don't care when others need one number and the slowing down is irritating at best.
Keep it basic but good, it's what people want to see. You've made it gimmicky. Take a look at your competitors, all have easy to read tickets with clear indications when you are getting closer to a line, house etc.
I've attached a screenshot which is from your sister site but is the same as unibet in how it presents.
