Casino promo slides are a rotating overlay panel showing your current offers, bonus codes and schedule, built from templates rather than designed — they work because a slide is readable in the two seconds a viewer glances at it, which a spoken plug is not.
The usual workflow for a casino promo on stream is depressing: message a designer, describe the offer, wait a day, get a PNG back, discover the bonus terms changed, ask again.
The problem is that the offer is baked into the image. Change one number and the whole asset is dead.
Separate the background from the message
A promo slide is really two things: something to look at, and something to read. Keep them apart and you can change either one without touching the other.
- Background: an ordinary photo or a short MP4. Slow movement — a gentle pan or zoom — reads as produced rather than static.
- Foreground: logo, headline, bonus line, button. Each one a piece you can drag, resize and retype.
When the offer changes, you edit a text layer. That is the whole job.
Import instead of retyping
If you already keep casino profiles — logo, bonus text, signup line, the affiliate link — a slide can pull them in already laid out. It removes the most common mistake in stream promos, which is not ugly design but wrong information: an old bonus amount left on screen for weeks because nobody remembered the slide existed.
What actually makes a slide work on stream
- One message. A slide is on screen for eight seconds and competing with a slot. Two offers is zero offers.
- Readable at 30% size. Most viewers are on a phone or a small window.
- A link they can act on. Say the URL out loud or keep it in a panel — nobody types a long link from a video.
- Compliance text. Age rating and responsible-gambling wording belongs on the slide, not in a caption nobody reads.
Preview where it counts
Design it in the same renderer that will show it. An editor that approximates the overlay will lie to you about font size and safe margins, and you'll only find out live. If what you see while editing is literally what OBS renders, the whole category of "it looked fine in the editor" disappears.
Promo slides are not a design problem. They are a maintenance problem, and the fix is keeping the words editable.
Frequently asked questions
How do you make casino promo slides without design skills?
Start from a slideshow template sized to your overlay, put one message per slide, and keep the text short enough to read in a glance. Complexity is the failure mode, not plain design.
How long should a promo slide stay on screen?
Long enough to read twice — a handful of seconds. Slides that rotate faster than a viewer can finish reading are worse than no slides at all.
What should be on a casino promo slide?
One offer, the code or short link to claim it, and the age and responsible gambling notice. Anything else competes with the single thing you want the slide to do.
