Load speed is one of the first criteria I look at. Especially nowadays, most people have no patience for waiting. This is also important for how the game handles a sudden incoming call or switching from Wi-Fi to 5G. If it crashes and I lose my session data, that’s a failure. Next criteria is the ‘Thumb Test’. Can I comfortably reach the main menu and the ‘Spin’ button with one hand? Finally, Battery Drain. If my phone turns into a pocket heater after playing a simple slot game for 10 minutes, that’s poor optimisation.
