# Playable Ads Built From a Message, Down to the End Card > Playable ad creatives for mobile game UA, built from a message. Layer makes the art in your game's look and exports one HTML5 file for your ad network. --- ## Messages to send, and what they made ### “Forge the rune set for Rune Blast: the four rune stones, the blast charges and the locked board tiles, keeping the carved arcane relief. Then build them into a playable: match-3 blast, eight moves, the enchanted board.” - ![A portrait match-3 board of carved rune tiles with a moves counter, a rune goal and a hand pointer showing the first match](/assets/881a7cb5-480.webp) [Play it: Rune Blast, match-3](https://media.app.layer.ai/workspaces/eaa1d118-365f-4960-97ac-99f4e86a860e/files/7454cd58-484e-4a07-b755-819c40efd6c7/match3%20puzzle_rune-blast.html) Eight moves and a rune goal counted on the HUD, with a pointer that teaches the first match before the player is on their own. ### “Forge the village kit for Hold the Village: the huts, the militia and the tree line, keeping the painted top-down look. Then build it into a playable: tower defence, one lane, the village to hold.” - ![A painted top-down village under attack, with a tutorial arrow saying tap the villager, then the tree, and a wave counter on the HUD](/assets/67162b29-480.webp) [Play it: Hold the Village, tower defence](https://media.app.layer.ai/workspaces/eaa1d118-365f-4960-97ac-99f4e86a860e/files/ec89bdac-4955-403c-8582-4544a5cdb6cb/towerdefense_hold-the-village-defense.html) The first taps are taught on the board itself (villager, then tree, then a hut) before waves start coming down the one lane. ### “Forge the reel set for El Dorado Spins: the idols, the glyphs and the gilded frame, keeping the jungle-gold look. Then build it into a playable: five reels, a bank to build, the jackpot at the end.” - ![A gilded jungle slot machine with five reels, a gold bank, bet and line controls and a tap to spin button](/assets/fcd2da54-480.webp) [Play it: El Dorado Spins, slots](https://media.app.layer.ai/workspaces/eaa1d118-365f-4960-97ac-99f4e86a860e/files/ae21e578-b552-41ce-95ac-4af28ab1c7b5/slots_eldorado-jackpot-slots-final.html) Five reels in a gilded idol frame, with a bank, bet and line controls that read like the real lobby the ad is selling. ### “Forge the counter for Merge Keys: the moon coins, the herbs and the three waiting customers, keeping the carved apothecary woodwork. Then build them into a playable: merge, orders on the board.” - ![An apothecary merge board of moon coins and herbs under three customers, each showing the order they are waiting for](/assets/6bdca538-480.webp) [Play it: Merge Keys, merge with orders](https://media.app.layer.ai/workspaces/eaa1d118-365f-4960-97ac-99f4e86a860e/files/6977d15a-d288-4227-9c35-440e23b8b067/merge%20puzzle-mystic-keys.html) Three customers post their orders above the board, and merging coins and herbs is how the player fills them. --- A playable ad usually means an artist, an engineer and days of back-and-forth for every concept, so most teams test far fewer ideas than they have. Each reskin for a new audience starts the loop again. Write the game, the look and the mechanic in a sentence or two. Layer writes the brief, makes the art and sound in your game's look, and builds the playable: one HTML5 file with an end card, an install button and a replay. The playable ad examples above are the builds those messages produced; press play on any of them. ## What Each Build Ships With **Install and Replay on every end card** Every card the player can reach carries both, and Replay never counts as an install tap. **Sound on by default** Effects on the taps and the wins, and a music loop, made for the build like the sprites. **Tweaks for the difficulty** On most genres, sliders for the balance, like the goal count on a match-3 board or the move budget on a merge board. The values you dial in go into the file you download. ## Balanced Before It Reaches You A playable that plays itself wastes the impression, and one nobody can finish loses the install. Layer runs bots against every build before handing it over. A board game has to resist random taps, a skilled player has to win with margin, and a player who does nothing has to lose. Tune from there: an easier and a harder version of the same build is two downloads. ## Change One Sprite, Keep the Rest Ask for a different hero, a new backdrop or a seasonal palette in the same conversation. Layer remakes only what changed and swaps it into the build. Keep the mechanic and test the look, or keep the look and test the mechanic. ## Export for Your Network Download the build packaged for AppLovin, Unity Ads, ironSource, Moloco, Meta, Google App campaigns, Liftoff, Pangle (TikTok) or Mintegral. For video creative from the same game, see [UA video ads](/use-cases/ua-video-ads). For more than twenty builds across genres, see [playable ad generation](/features/playable-generation). ## Frequently Asked Questions ### Does Layer build the playable itself? Yes. From your message Layer writes the brief, makes the sprites, backdrop and sound, and builds the playable as one HTML5 file with everything inside it. You can play it in a browser straight away and upload the same file to your network. ### Will it look like my game? When it has your look to work from, yes. Attach a screenshot, key art or a brand kit and the art is made to match; each playable above kept the look its message named. With nothing attached, Layer asks where the art should come from before it builds. ### Will ad networks accept the file? It is built to their spec. One portrait file, with every install tap sent through MRAID rather than a hard-coded store link. Pick the network when you download and Layer packages it the way that network takes delivery, a single file or a zip, and warns you if the build is over its size cap or needs ES5. The network's own review still decides. ### How is the difficulty set? With bots, before you see it. On board genres such as match-3 and merge, random taps must not reach the goal. On every genre, careful play has to win with room to spare and doing nothing has to lose. --- Create a free Layer account and describe the playable you want to test first. --- [View original](https://layer.ai/use-cases/playable-ad-creatives) | [All Use Cases](https://layer.ai/use-cases)
