About these challenges
Work through the clues at your own pace. A hint is available for each question, and you can review every answer at the end.
Which panel comes next?
Two changes alternate. Each change moves the arrow, the dot, or both by a fixed amount.
Show how it works
Find the two alternating changes
First change: the arrow turns 90° clockwise; the dot stays still. Second change: the arrow stays still; the dot moves 135° clockwise.
Use the second change next
The five visible transitions are first, second, first, second, first. Apply the second change to panel 6.
Panel 6Panel 7Complete the next panel
Arrow pointing lower right; dot at upper right. Both features must fit.
Panel 7
Which panel comes next?
Two sequences are interleaved. In each one, the arrow and dot move by fixed amounts.
Show how it works
Separate alternate panels
Panels 1, 3 and 5 form one sequence. Panels 2, 4 and 6 form another. Panel 7 continues the first sequence.
Panel 1Panel 3Panel 5Follow the odd-position sequence
From panel 1 to 3, and from 3 to 5, the arrow turns 90° clockwise and the dot moves 90° clockwise. Repeat those changes from panel 5. The even sequence has its own fixed changes.
Complete the next panel
Arrow pointing upper right; dot at up. Both features must fit.
Panel 7
Which panel comes next?
The arrow turns in one direction by an increasing amount. The dot moves by a fixed amount.
Show how it works
Compare the turns between panels
The arrow turns 90°, 135°, 180°, 225°, 270° clockwise. Each turn is 45° larger than the previous turn.
Continue both rules
The next arrow turn is 315° clockwise. The dot always moves 45° clockwise.
Complete the next panel
Arrow pointing lower right; dot at upper right. Both features must fit.
Panel 7

How this data is usedHelp
Each panel shows triangles inside a ring, with one dot on the ring. Five things can change: how many triangles there are, how big they are, whether they are filled, which way they point, and where the dot sits. Check one thing at a time against the four panels. Every panel also has a written description, so you can read it instead of looking at it.
Select one of four answers, then choose Check. You can change your selection before checking. Read the explanation and continue when ready. Keyboard: Tab to the answers and use the arrow keys to change your choice.
Easy changes one thing from panel to panel. The triangles turn, or the dot moves. Easy offers panel 4 again as one of the four answers on about half its boards. Standard plays those same boards and adds one where the triangles turn and the fill flips together. Standard offers panel 4 again on about one board in five. Challenge always changes two things at once, and those two can also be the count, the size or the fill.
Solving time excludes setup, explanations and background tabs. The optional challenge gives you two minutes of solving time across six questions. When time runs out, unanswered questions count as incorrect. Timed and untimed results stay separate.
The browser loads a complete six-question round from the server when you start or restart. Completed rounds and timed-out challenges are saved when browser storage is available; ending early is not saved. Your individual answers are not uploaded.
A score here says how many of these six questions you answered correctly. It does not measure intelligence and it is not an IQ test or a selection test. Every round uses different questions, so scores move around.
Keyboard: press an answer's letter or number to choose it, Enter to check, and Enter again to continue.
