1. Make it Scalable
Icons are used in several formats and in multiple sizes. Your icon needs to hold up to the standard while remaining unique. Make sure your icon looks good and fits all mobile devices, whether it’s iOS, Android, or both.
2. Use Contrasting Shades & Colours
The contrast makes characters and elements stand out. If your icon’s main element is light-coloured, go for a dark background. If it’s dark, choose a lighter background for your icon.
3. Make it Iconic
Find a unique element and customize it so it’s recognizable. You can make it dynamic by adding some action (use a clear character shape), using the character facial expression, and doing for contrasting colours.
4. Minimize the Colour Palette
Colours help your game grab the player’s attention, but don’t use too many – 1 or 2 colours are enough. Simple icons drive much more conversion than complex ones.
5. Keep it Simple
Icons need to be clear & simple to understand, so focus on the one object only. An icon that’s too complicated will fail to communicate to your players what the game is all about.
