The Double Turn (known as the Tunnel in Open Hexagon) is a pattern in Super Hexagon and Open Hexagon. It is featured in Hexagoner, Hyper Hexagoner, Hexagonest, Hyper Hexagonest and The Final Hexagon. It involves turning right 240 degrees (four segments), then left 240 degrees, or vice versa, for a minimum of 480 degrees. Generally, this is one of the easier patterns to learn and is very simple to master in any situation, but it can occasionally catch players off or exploit minor errors in player input, especially in Hyper Hexagonest, causing frustration within these Levels.
