Game Review Requirements

Please make sure your game meets or exceeds all of these guidelines before it is submitted. These guidelines ensure that your game can reach the widest audience possible and that players have the best experience possible.

Metadata

All of your metadata must be provided in both English and Japanese. Make sure your supported languages are accurate for the localization provided in the game.

Your Game "Description" maximum character limit for English is 48 and 22 for Japanese.

Your “How to Play” instructions must be clear and easy to understand. Please make sure your menu is set to a position that does not interfere with the game’s UI or functionality. A banner image and icon image must be provided and be appropriate for the game.

Make sure the orientation is set correctly for the resolutions the game supports. The description must be short enough to display on mobile view.

Icon & Banner

An icon image and banner image must be provided and appropriately represent your game. For tips about making an awesome icon for your game, please refer to our Best Practices guide.

Icon - Your game icon must be a square image at least 628 x 628 pixels. Please do not cut, trim or round off the corners as we will take care of that on our side.

Banner- When your game makes it into the “Featured Games” section on a publisher’s Game Portals, it is displayed using a slightly bigger banner image. Banner images must be a ratio of 2:1 (width x height). Our recommended banner image size is 1256 x 628 pixels.

Functionality

General

Please make sure your game works as expected and all core features of the game are functioning properly before you submit it. No freezes or crashes should occur while playing the game. No errors should be displayed in the browser console that originate from the game build.

Mobile Compatibility

Your game must be playable on mobile and tablet devices. Therefore, your game should cover the entire screen in either portrait or landscape orientation.

Aspect Ratio

Your game must have an aspect ratio 9:16 or 16:9 that allows it to completely cover the canvas on any device. We recommend dimensions 1920x1080 or 1080x1920 in order to scale it down easily.

Controls

Make sure your game responds accurately to touch input on mobile devices and tablets. For PC players, please make sure the game responds to keyboard and/or mouse input on desktop computers and laptops.

User Interface

Ensure that all of your game’s UI elements are functional. Make sure there are no dummy buttons, empty menus, etc. Buttons and other elements should be sized/scaled appropriately and should not create accessibility issues. All buttons and other elements should be clearly labeled and function as intended. Eliminate any hidden overlays, click-jacking, etc.

Performance

Your game should load in an acceptable amount of time - the faster the better! Make sure your logging is set to production level and that the console isn’t flooded with debug information.

Remote Assets (If Applicable)

Remote assets should load in an acceptable amount of time. User feedback should be given when the game is blocked due to assets loading. Error handling should be implemented for any case where remote assets fail to fetch or load.

Incognito Mode

Your game must be playable in Incognito Mode. Incognito Mode blocks access to a device’s localStorage. To solve this issue, please implement a try/catch block for your game’s localStorage operations.

Ads

General

Wortal SDK must be integrated. No branding or external ads are allowed. All splash screens and outgoing links must be removed. You may display your logo during the loading screen, but not during actual gameplay.

Pre-Roll Ads

Pre-roll ads should display when using Wortal/AdSense. The game should not display Canvas before the pre-roll ad finishes. The game should not play audio before the pre-roll ad finishes.

Interstitial Ads (If Applicable)

Interstitial ads should be called for at an appropriate time in the game, for example, when a level is finished, the player leveled up, or at timed intervals for games with long levels.

The game should pause gameplay and audio when BeforeAd is reached. It should resume play and audio when AfterAd is reached. The game should also resume properly if NoShow is reached.

Your game should not make repeated/duplicated ad calls in a short period of time, for example, if a button calls for an ad, the button must be disabled for a period of time after the player presses it or the button may be pressed rapidly and call for many ads.

Rewarded Ads (If Applicable)

Rewarded ads should be called for at an appropriate time in the game, for example, if a player has died, a rewarded ad is offered to allow the player to revive and continue playing with their current game progress. Rewarded ads should only be shown after the player has agreed to watch. For example, if a player clicks a button with the video icon that says “Watch Ad for 2x Bonus.”

The game should pause gameplay and audio when BeforeAd is reached. It should resume play and audio when AfterAd is reached. The game should also resume properly if NoShow is reached.

The player should be rewarded if they complete the ad, but if they dismiss the ad, they should not be rewarded.

See Ad Ideas in our Best Practices Guide for more tips on how you might incorporate rewarded ads into your game for the most player enjoyment.

Content

Legal

Your game shouldn’t infringe on any trademarks or copyrights. Your game should not be a clone, copy, or too closely resemble another game on the platform.

Your game should not include nudity, adult content, or content that could be considered offensive.
