Submitting web games requires cover images across square, portrait, and landscape aspect ratios alongside metadata including title, short and long descriptions, category tags, supported devices, orientation, and supported languages. Requirements vary slightly by destination, so verify pixel dimensions and asset specifications in each upload form before submitting your build.
At a glance
| Fact | Value | Source |
|---|---|---|
| Common cover shapes required | square, portrait, landscape | |
| Poki categories a developer can pick | up to four | developers.poki.com |
| First impression factor Poki checks | thumbnail + fast opening | developers.poki.com |
Almost every web game portal asks for the same core set before it will review a build:
- Game title, short and long descriptions, and how-to-play instructions
- Supported devices, supported languages, and screen orientation
- Cover images in fixed shapes (typically square, portrait and landscape)
- Category tags (for example, Poki lets developers pick up to four)
Publishing through Playgama requires uploading these covers and details through developer.playgama.com.
Before submitting anywhere: confirm the exact pixel dimensions each portal’s form requires for covers, keep file size lean for fast load times, and make sure orientation and supported-device fields match what the build actually does.

Do all portals require the same cover sizes?
No. Each portal specifies its own exact pixel dimensions for square, portrait and landscape covers – check the upload form on each destination before exporting assets.
Does the thumbnail actually affect approval?
Poki’s own guidance says players decide in seconds, so a clear thumbnail and an immediate playable opening matter as much as the game underneath.
