A. To avoid accidental spending of diamonds, be cautious when tapping on items or features that require diamonds. Familiarize yourself with the game interface and double-check before confirming any purchases. You can also adjust your settings to limit accidental taps by being more deliberate in your actions.

B. Consider keeping your diamonds in reserve for essential upgrades or purchases only. This way, you will be less tempted to spend them on non-essential items.
