How playtest works

What it does, how it grades, and what each plan includes.

What is playtest

playtest shows Roblox creators why their game isn't growing and the one thing to fix first. It reads your game's numbers, puts them in plain words next to similar games, and picks fixes for your kind of game.

  1. 1See what is wrongOpen your game in Creator Hub. playtest grades how well you get plays, keep players and bring them back.
  2. 2Fix one thingEach problem comes with one fix to try first, picked for your kind of game.
  3. 3Test itGrade thumbnails before you upload them, and on Solo Creator, test titles and thumbnails on real players.

playtest is an independent tool built on Roblox's official Open Cloud APIs. It is not part of Roblox Corporation.

Thumbnail grader

The score runs in your browser, so your image is never uploaded. It checks five things and turns them into a letter grade from A to F.

CheckWhat it looks atWeight
Phone sizeIs the main subject still readable at the size players see on a phone?25%
ContrastDoes the subject stand out from the background?25%
ClutterIs there one clear focus, or too much going on?20%
BrightnessBright enough for the feed, but not washed out.15%
Color popAre the colors strong enough to catch the eye?15%

Second opinion

A second opinion on your thumbnail, from an AI model that looks at it the way a player would. It scores five things, gives an overall letter grade, and lists three fixes.

  • Would a kid click it?
  • Proportions: is the main subject big enough at phone size?
  • Makes you curious: danger, humor, a mystery or a big reward.
  • Title and image match.
  • Clear what the game is in one second.

Credits refill at midnight UTC. Checking the same image and title again is free.

Roblox is for kids, so images that are not OK for kids are never graded, and the account loses AI grading.

Genres

Pick your game's genre to compare your thumbnail with popular games like it. The basic checks still apply. A genre only changes how bright and how busy a thumbnail can be, and adds tips for that genre.

Genres: Simulator, Tycoon, Obby, Horror, Shooter, Fighting / Battlegrounds, Roleplay / Life, Racing, Survival, Other.

A/B tests

  1. 1Set upSign in with Roblox, add the Chrome extension and pick your game. No API keys needed.
  2. 2ThumbnailsAdd 2 to 5 thumbnails in Creator Hub (Places, Thumbnails, Home Page). Roblox shows each to a share of players, and playtest reads the results for you.
  3. 3TitlesWrite 2 to 4 titles. playtest swaps them on Roblox for you and tracks who saw each one and who pressed Play.
  4. 4How a result is calledTitles switch in turns, so each one sees similar hours. One is called ahead only when every version has 1,000+ views, each has been live at least 3 times, and the result is 95% certain. Often there is no clear winner, and your current title stays. Tests run about 5 days.
  5. 5The winner stays liveIf nothing clearly wins, your original goes back.

Click rate is the share of people who saw your thumbnail on Roblox and pressed Play. 250 plays from 12,480 views is 2.0%.

Icon swaps stay manual: icon tests remind you when to swap and track the result.
