Same or different?
Spot the relationship in a set of images.
Try this taskThree pattern puzzles. One life.

Start with a visible pattern, then work with a brief glimpse and a rotated shape. The pigeon challenge asks you to notice relationships, remember what you saw and separate rotation from reflection.
The first task asks whether all symbols match. The second covers the pattern before you answer. In the third, the original stays visible while you choose its rotated copy. Look at the arrangement and handedness, rather than one familiar detail.
Spot the relationship in a set of images.
Try this taskThe image disappears. The relationship remains.
Try this taskRecognise the same shape from a different angle.
Try this taskThree tests with five rounds each. You have one life: every round must be correct. Tests become harder automatically, from Light through Medium to Demanding. Before each test, take your time with the rules and example. Choose relaxed or sport tempo; the clock starts when you start the task.
Open one task and read its goal and example before starting. Training lets you choose the task profile and tempo.
Each task has five rounds. Training allows one wrong round; one-life challenges require all five to be correct.
