: To dominate weekly events and secure the 400-gem gold medals, some players intentionally keep their single-player campaign rank low. This prevents them from being placed in higher-tier competitive brackets before their planes are powerful enough to compete.
: The most efficient way to get high-tier gear for free is by grinding Special Events . By repeating specific levels (like Level 41 on Hard), players can earn the 4,000 daily points needed to unlock Tier 3 planes, wingmen, and devices without spending money.
: Investing gems in a five-star copilot is mathematically superior to many other upgrades. A high-level copilot can increase your power by nearly triple on Tier 2 planes, making difficult levels significantly more manageable. Progression Warning
