Grid trivia, strategy and daily challenges.
These pages describe DoubleQross 1.0, the App Store release. Earlier TestFlight builds used different scoring and screens.
Answer your way from one corner of a colored grid to its opposite. Correct answers open a route; wrong answers burn cells and cost lives. What you know and where you go both matter.
Choose boards from 4×4 to 8×8 and up to 16 topics from a growing library. Face Up, Face Down and Blind change how much of the board you can see.
In Double Cross, finish your first diagonal, then choose either unused corner as a new start and cross to its opposite. No walk between starts. Revisit solved cells without another question; every move still counts.
Higher points are better. Perfect Single scores range from 500 on 4×4 to 1,000 on 8×8. Double Cross doubles those ceilings. Completed games rank above unfinished attempts. See scoring and assist costs.
One attempt per UTC day on a 5×5 Single board. Build your daily play streak and compare results on the leaderboard. Questions are drawn from each player's pool, not an identical worldwide quiz.
