What lobby art has to do

Before anyone plays a slot, they see its tile in a casino lobby, usually in a grid of dozens of others. The tile is the game's first impression and often its only one, so it has a narrow job.

• Show the name. The title has to be readable at the size the lobby shows it, which is far smaller than on the game's own stage.
• Show one face. A recognisable character or focal object tells a player what the game is about faster than a scene does.
• Survive cropping. Lobbies crop and resize. The title and the focal subject need to sit inside crop-safe bounds, away from the edges.
• Match the game. A tile that promises one look and opens onto another loses the player in the first second.
• Come in more than one shape. A square tile for the grid, a wide banner for featured rows, and a loading screen that holds the same identity while the game starts.

What the generator delivers

Every set includes its front matter: four compositions built from the set's own finished art.

Each composition cover-fits the background to its canvas, then places the 1200×400 title across the upper part and the 512×1536 mascot in its own slot, each at one uniform scale so nothing is squashed. The slots are written to asset-set.json with each file, and on the splashes the manifest also places the 1200×400 progress track. A set without a mascot gets the same compositions with the title alone. The mobile splash is built on the separately composed phone background, so it is not a crop of the desktop splash either.

These compositions cost no generation. They are made in code from art the set already paid for, which is also why they can only be as good as the title, mascot and background they are made from.

The front matter also includes info/paytable-panel.png, a 1200×800 empty framed panel. That one is generated; the client prints the pay values into it.

Sizes the set does not make

Every operator and aggregator publishes its own thumbnail specification, and those change. The set does not guess at them. Make the crops a publisher asks for from the delivered tile, banner, background, title and mascot, at the sizes they request. Do not stretch the 16:9 banner into a square: the tile exists so that you do not have to. The slot game asset checklist covers what else a distribution handoff needs.

Why lobby art belongs inside the set

Lobby art made separately is usually a new illustration of the game: a different artist's version of the character, a title redrawn for the tile, a scene that never appears in play. It can look good and still misrepresent the game.

Here the tile is the game. The background is the stage the reels sit on, the title is the lockup above the cabinet and the character is the same mascot that stands beside the reels, all drawn against one style board and numeric style contract. Nothing is redrawn for the lobby, so the tile cannot drift from what the player opens. The set consistency guide explains how those three assets are held together.

How to steer the lobby art from the brief

There is no lobby field. The lobby art follows the three assets it is built from, so steer those:

• Game name. The title spells it exactly as typed. Shorter names give larger letters on a small tile.
• Mascot direction. A character with a clear silhouette and one strong colour reads at thumbnail size. A busy costume does not.
• Theme. The place and light set the background behind the title and mascot. Clear light gives the tile a clear value range.
• Style, palette and extra direction. These apply to all three source assets at once.

The slot logo generator and slot mascot generator pages cover those two assets in detail.

Changing the lobby art

The lobby tile and banner have no redraw of their own, because there is nothing to prompt: they are compositions. To change one, redraw the title, the mascot or the background with a note. The redraw builds a candidate beside the current image while the accepted set stays as it is, and the lobby art is composed from whichever versions you accept. One game set is $19 and includes ten redraws.

Start a set

Begin at a new game with a game name and theme; the lobby tile, banner and splashes come with the finished set. Each game in the showcase shows the title, mascot and stage its lobby art is built from.
