Ease of Play

Check Your 6! was designed to reflect the realities of air combat with the simplest wargame mechanics possible. Instead of endless die modifiers, CY6! Utilizes multiple die types and innovative mechanics to enable players to think about the air fight instead of what chart to look at.


The Check Your 6! rulebook has over 20 scenarios but has been followed by more than 10 Campaign Books in a SkirmishCampaigns-like format, with more being written. See this webpage for more details and see the Example Scenario above.


Both Check Your 6! games were designed to closely reflect the realities of WWII and Modern air combat while allowing for a playable game. Combat is reflected in 3D, and the game is the result of two years of research into Air-to-Air, Air-to-Ground, and Ground-to-air weapons, combat maneuvers, aircraft statistics, and the influence of pilot skill on combat. Statistical analysis was extensively used to find the most efficient game systems. In addition, former US Air Force and US Marine Corps pilots were a part of the design team from the start, greatly influencing the design and playtesting.
