I began playing Angry Birds Epic the other day and was surprised when I saw their store (screenshot above). The screen to buy coins shows 4 packages for the player to choose from. Simple enough. Except there are actually 6 coin packages to choose from.
The player is oblivious to the other 2 packages because there is no visual cue that there are more options available.
There are many times when you want to show a mobile user a list of options, but all the options don’t fit on the screen at once. In this case it’s best to have the next item “peek” out from the side, indicating to the user that there is more to see if he/she scrolls.
Here’s how the same screen would look with this in place. It’s much more obvious that there is more to see if the players scrolls right.
It’s surprising to see Rovio, a company well-versed in mobile, make such a rookie mistake.
You can see a slew of other mobile games that follow this best practice below:
