Should I use a higher or lower DPI for mobile casino game interactions?

In mobile casino games, lower is better when it comes to DPI. Because why not? Larger buttons are great for multi-touch screens, particularly those being handled by one hand while on the move. A high DPI will cause buttons to feel crowded and be accidentally tapped – something that’s really frustrating when you’re in the middle of landing a royal flush.

But don’t go too small. Make sure that buttons still look good (the tap target size across different devices should be no less than 8-10mm). The player shouldn’t have to strain his eyes to push the correct button.

A second piece of advice: keep touch fatigue in mind. If there are many buttons that players must push frequently (spin, bet, menu, and so on), don’t make them too small or grouped too closely together. And ensure that the buttons don’t get in players’ way. After all, we don’t want players to be trying to operate the interface rather than playing the game.

Lower DPI (dots per inch) is generally preferable in mobile casino games because it improves touch sensitivity. This is important to consider given that players may be on the move or not particularly precise when touching the screen. Too high a DPI could lead to button elements appearing too close together or increase the chances of accidental tap-through. Make sure buttons remain clearly distinct and identifiable. Players will thank you for it.
