Two ways, both on the phone in your hand. Option A is free and already built into iOS. Option B is Paused, if you'd rather it happen automatically and be harder to tap past.
Free · built into iOS
Option A — Apple Screen Time
No download, no subscription. Apple's own App Limits can block DoubleDown Casino specifically, and Downtime can switch it off by time of day.
Turn Screen Time on. Open Settings → Screen Time. First time? Tap Turn On Screen Time, choose "This is My iPhone", and set a Screen Time passcode — pick four digits you won't type on reflex at 11pm.
Add an App Limit. Still in Screen Time, tap App Limits → Add Limit.
Select DoubleDown Casino. Apple sorts your apps into broad buckets and DoubleDown Casino sits with the Games apps. Tap the arrow beside Games to expand it and tick DoubleDown Casino only — or just type "DoubleDown Casino" into the search field at the top, which is faster. Tap Next.
Set the allowance. Choose how long DoubleDown Casino gets each day. 30 minutes is a soft cap; 1 minute is effectively off. Tap Customize Days if weekends should be different, then tap Add.
Turn on Block at End of Limit. Reopen the limit you just made and switch on Block at End of Limit. Without it, the "Ignore Limit" button hands the whole evening straight back to DoubleDown Casino.
Add Downtime for a time-of-day block. A daily budget isn't the same as "off after 10pm". For that, go back to Screen Time → Downtime → Scheduled and set the window (10pm–7am is the classic), then check that DoubleDown Casino is not listed under Always Allowed. During Downtime it's blocked outright — there's no allowance left to burn.
The honest catch: it works, but it's four screens deep in Settings, the limit resets its own way, and if you know the passcode you can undo it in about six seconds. That's why so many people set an App Limit once and never think about it again.
Automatic · one tap
Option B — block DoubleDown Casino with Paused
Same Apple blocking engine underneath, built for the one job: getting DoubleDown Casino out of your evening without you having to decide again every night.
Create a Block Schedule. Open Paused and create a Block Schedule — that's the recurring, automatic kind.
Pick DoubleDown Casino. Choose DoubleDown Casino from your installed apps. While you're in there, add the rest of your games time-sinks too — Lightning Link Casino, Heart of Vegas, Match Masters — because DoubleDown Casino is almost never the only one.
Choose the window. Set the days and hours: 10pm–7am so the night is yours, 9–5 for work, or 7–9pm so dinner and the evening stay phone-free.
Save it and forget it. That's the whole setup. From then on DoubleDown Casino turns itself off when the window starts and comes back on when it ends — no willpower, no remembering.
Use a Focus session when you need DoubleDown Casino gone right now. One tap starts a Focus session: pick a length — 25 minutes, two hours, until dinner is over — and DoubleDown Casino stays locked until the timer runs out.
Let the streak do the rest. Every day you keep the block stacks your streak. That's the part that keeps this working in week three, once the novelty of a fresh limit has worn off.
What it can see: nothing. Paused blocks through Apple's Screen Time (Family Controls) framework, so it can stop DoubleDown Casino from opening without reading your messages, your browsing, or anything you do inside the app. Your usage stays on your device.
Why DoubleDown Casino is hard to put down
Daily wheel spins and hourly bonus chips give you a reason to open it long after the fun has worn off.
Which is the point worth sitting with: you're not weak, you're up against a team of people whose job is the next tap. That's also why "I'll just be more disciplined" keeps failing and a dumb, boring wall — DoubleDown Casino simply doesn't open between 10pm and 7am — keeps working. Put the decision somewhere your 11pm self can't reach it.
And block the neighbours while you're there. Closing DoubleDown Casino and landing on the next games app in the same second is the most common way this falls apart — so block the cluster (Lightning Link Casino, Heart of Vegas, Match Masters), not the single worst offender.
