Memory Tails
Production advertising is not live yet. The planned Android release uses Google Mobile Ads and Google's User Messaging Platform. It may show a banner during active gameplay and an optional rewarded ad that grants one Repair. Ads are requested only after the required consent process is complete.
Android users may make a one-time Remove Ads purchase. While a valid entitlement is active, Memory Tails does not request or display banner or rewarded ads. The iOS version is currently ad-free.
Piecehaven
The current Piecehaven Android release is available on Google Play, with regional availability shown by the store. Placements, rewards and version-specific test features are distinguished below; availability depends on your installed version. iPhone and iPad have not been published and have no announced release date.
The public Piecehaven game is free with ads. Supported Android versions offer the optional one-time Remove Ads purchase described below. Google Mobile Ads supplies advertising, and Google’s User Messaging Platform handles regional privacy choices. In Android build 197 and later, eligible players without an active Remove Ads purchase may see a labeled banner from their first puzzle, in the gameplay footer or side panel, and a banner after collection-browsing content.
A preloaded full-screen ad may appear when you explicitly resume a saved puzzle, confirm an eligible restart, or finish a qualifying puzzle, including the first completion after its celebration and before the reward screen. Starting a new puzzle (including Create & play) can show one only after a previous win; the initial Start before the first win does not. A completion that requests reminder permission skips the completion ad. Earlier Android builds and iOS build 152 retain their version-specific placements; these new Android placements do not describe build 152. These placements share a minimum three-minute gap and limits of six per session and twelve per local day; a new session begins after the app has been in the background or closed for at least 30 minutes. No unsolicited full-screen ad interrupts an active solve or Replay. If an ad is unavailable, the app continues without waiting for a load or scheduling a delayed ad.
Optional rewarded ads can give one bonus Classic hint after the installation’s three free hints, or one Reference opening after its separate three free openings in supported Android versions. An active Remove Ads purchase gives unlimited Classic hints and Reference openings, and available past Daily puzzles open without a video. Older versions may count committed reference changes. Clearly labeled choices may also unlock an eligible cosmetic background, saved assembly replay or missed Daily puzzle. Coin videos (a 10-coin video, the Daily gift video and an optional video bonus after a completed puzzle) are credited only after server verification. In Android build 197 and later, the welcome starter can also offer this optional completion video bonus after the server accepts its completion. Earlier Android builds and iOS build 152 do not offer the starter video bonus. Collecting the ordinary completion reward does not require watching a video. Timed has no hints or reference guide. Rewards require the provider to report that they were earned, not simply that an ad closed. Background rewards remain on this device, are not purchases, and may be lost when local data is removed. An unavailable optional reward does not prevent ordinary free play.
Guest play does not require a birthday. The Android release is intended for adults aged 18 and older. Guests who have not entered an age and teens receive restrictive, non-personalized ad treatment with a G maximum content rating; on Android, players located in the United States who have not entered an age may receive personalized ads when that feature is on, subject to Google’s consent and US state privacy choices. A known age under 13 does not initialize advertising. Ad requests depend on the completed welcome, age eligibility, regional consent, available inventory and provider approval. Reopen Profile → Settings → Privacy & data → Advertising privacy choices when the consent service makes that option available. The planned iOS version requests non-personalized ads and disables Google’s publisher first-party ID; advertising providers still process data for delivery, measurement, security and fraud prevention.
Optional Android purchase. A one-time, non-subscription Remove Ads purchase is available in supported Android versions. The US base price is $4.99; Google Play displays the applicable local price and purchase terms before confirmation. A verified active purchase removes banners and automatic full-screen interstitial ads, including puzzle starts and restarts, and gives unlimited Reference openings and Classic hints. Available past Daily puzzles also open without a video while access is active. Using a hint still counts in puzzle statistics. Optional reward videos remain available for their stated benefits, including coin and Daily gift bonuses. It does not grant coins, unlock coin-priced Collections or change Timed mode, and it does not transfer to iPhone or iPad. Google Play may also report attributed purchases and their value to our linked Google Ads account to measure advertising performance. This store-provided reporting is separate from optional in-app Gameplay Analytics.
Limited internal Android testing also covers contextual, non-personalized ads for eligible guests whose age has never been entered and whose network country is Mexico or India. Age remains unknown: this is not an adult declaration or consent to personalized ads. This test is for consenting adult testers. Eligible requests do not apply child age treatment solely because age has never been entered. The internal country-policy service uses the network country rather than precise GPS location. Requests keep a G maximum content rating and the required Google consent choices; known-minor and invalid-age protections remain. Non-personalized ads can still use device, advertising or app identifiers for frequency capping, reporting, security and fraud prevention. Gameplay Analytics and Meta measurement remain separate choices. This Mexico/India policy is not enabled in the public Android or iOS release.
Supported newer iPhone and iPad versions use the same banner, resume/restart, completion and post-win start placements and frequency limits described on this page, subject to iOS privacy eligibility, purchase status and ad availability. They may also offer the optional starter-completion video bonus after server verification. The Android-only country policies do not apply to iOS.
Supported iPhone/iPad versions also offer a separate one-time App Store purchase that removes banners and automatic interstitials while leaving optional reward videos available. They can offer optional Gameplay Analytics and Google Ads sharing; sharing requires Apple’s tracking authorization as well as the app’s choices and eligibility. Analytics IDFA and IDFV collection remain disabled. These features may be tested in TestFlight before an App Store release; the game is not yet publicly available on iPhone or iPad. Read the iOS disclosures and the Piecehaven privacy notice for platform differences, privacy choices and optional measurement, or Piecehaven support for help with ads and rewards.
Route & Deliver: Cozy Puzzles
The published Android and iOS versions include Google Mobile Ads. Ad availability depends on region, the saved age group and privacy choices. The Android and iOS integrations use Google Mobile Ads and Google's User Messaging Platform, with no mediation adapters or real-money purchases.
The game is intended for adults aged 18 and older. After the policy agreement, it asks once for the player's year of birth and keeps only the resulting age group (18 or older, or under 18) on the device; the year is not stored, and policy agreement does not establish an age. Players under 18 and players who have not answered yet keep child-directed treatment, a G content limit and non-personalized requests. Players 18 or older receive adult ad treatment: a mature (MA) content limit with some sensitive categories blocked, and personalized ads where their US state privacy choices allow on Android; iPhone and iPad ad requests stay non-personalized. Child, teen and unknown-age choices saved by older versions are never changed to adult and keep banner-only restrictions, with no rewarded videos or interstitials. Required Google privacy checks remain separate from the game's policy agreement. Fullscreen advertising also depends on the saved age group and placement eligibility.
The Android app declares Google's Advertising ID permission. The permission applies to the whole app, so Google's SDK can access the Android advertising ID on any install, whatever age group is saved. Google states that requests tagged as child-directed or under the age of consent do not send the Android advertising ID; the game tags every ad request that way unless the player confirmed they are 18 or older, so, according to Google, only adult players' ad requests can include it. The iPhone and iPad version never requests Apple's app-tracking permission, so the advertising identifier (IDFA) is not available to the app or its ad and analytics SDKs.
Eligible players may explicitly choose videos for bonus coins, one extra hint after the profile's three free hints shared across Campaign and Daily, or one rewarded continue per attempt after Game Over. New levels, dates and retries do not refill the free allowance. A continued run earns one star and uses assisted records without enabling Assist. The continue limit survives a restored checkpoint and resets with Start Over.
Wallet videos give 10 coins and Collection videos give 25; they share a limit of three earned coin videos per UTC day. Collection videos can also be chosen from an item preview when more coins are needed. Separate optional videos can double a saved completion reward or add 20 coins to the Daily login gift's already saved 20 coins. Rewarded inventory may load in advance after privacy and eligibility checks, but a video still requires a player's explicit choice and a confirmed earned reward that the game can save.
Aggregate advertising counts and Google-reported ad values are kept locally for at most 31 recorded UTC dates. These summaries are not uploaded to Marble Comet and contain no account or device identifiers or raw ad-provider payloads. Test-ad values are not income. Separately, for players 18 or older, Google Analytics for Firebase records gameplay events and the ad impressions and revenue reported by Google AdMob, with ad personalization denied and Google signals off; they can turn it off in Settings → Ads & privacy → Usage analytics. Players under 18 and players who have not answered the age question are not measured. See the game's privacy notice for details.
Banners appear only in a fixed gameplay footer; Map, Daily and Collection screens have none. An already visible gameplay banner stays in place through pickup and dragging. New presentation waits for gestures to finish, and pause screens, dialogs, backgrounding and other interruptions hide the banner. Its reserved footer never moves the board on load or no-fill. Opening a banner destination pauses play and requires Resume on return.
Eligible interstitials are paced at natural breaks: when leaving a saved campaign success, or after choosing Start Over from Game Over. Completion ads have a 50% chance once per eligible saved result, after the first five distinct campaign clears, at least three completed campaign runs since the previous full-screen ad, and 120 seconds of active gameplay since that ad. Restart ads have a 35% chance after the first five distinct campaign clears, at least three failure restarts, and 120 seconds of active gameplay since the previous full-screen ad. Success and restart placements share spacing; rewarded ads reset it too. Daily Puzzles and instructional levels have no restart interstitial. Only preloaded inventory is used; an unavailable ad lets navigation continue immediately without a delayed interruption.
No fullscreen ad opens automatically on collision, app launch, or a world reveal, and none interrupts an active drag. Puzzles, remaining free hints, saved hint credits, and free restarts work offline. Extra video hints require an eligible rewarded ad and an explicit Watch ad · 1 hint choice; opening Hint does not automatically show a video. Showing the same saved route again before another delivery is free. Google's publisher first-party identifier is disabled on both platforms, and no Apple app-tracking permission is requested. Google still processes advertising and consent data. See the Route & Deliver: Cozy Puzzles privacy notice for data practices and choices.
Authorized sellers file
The studio's app-ads.txt publishes the authorized-seller row shown in its verified AdMob account. Publishing the row lets participating advertising systems confirm that Google is authorized to sell Marble Comet inventory. It does not show whether a particular game is publicly available or currently serving ads.
