Just a quick try. Not saved; no game rewards.

ExplorePosition and order

The whole row is turned around, so the left end becomes the right end. Which figure is now 4th from the left?

  1. triangle
  2. diamond
  3. star
  4. square
Need a hint?

Write down the new order of the figures after each change. Then read off the place asked for.

Answer & method

ReasonRepeating patterns

What colour is the shape in the box with the question mark?

?
  1. purple
  2. blue
  3. red
  4. green
Need a hint?

Look at how often the colour repeats. Then carry on the pattern.

Answer & method
Answer A: purple

The colours repeat every 2 figures, so the next one is purple.

StretchDirection sense

Start at the coral dot. Go north 2, then east 1, then west 2. Which square do you reach?

NABCDE12345
  1. A3
  2. B3
  3. B4
  4. C3
Need a hint?

East and west change the letter. North and south change the number.

Answer & method
Answer B: B3

The walk ends at B3.

Ideas to practise

  • Position and order. Use the given left-to-right order, then count or locate a neighbour.
  • Coding and decoding. Apply the stated code consistently to each letter.
  • Number patterns. Look for the same change between neighbouring numbers.
  • Repeating patterns. Find the smallest repeating group and continue that group.
  • Sorting by a rule. Check which object does not share the named property.
  • Ranking and order. Include the person being counted when converting a rank from one end to the other.
  • Possible combinations. Match each choice in the first group with every allowed choice in the second.
  • Reflection and symmetry. A mirror reverses left and right, but not top and bottom.
  • Working backwards. Undo the last operation first, then undo the earlier operation.
  • Direction sense. Track north/south and east/west movements separately.
  • Routes and constraints. Follow only the allowed paths. At a junction, add the ways arriving from its incoming paths.

A game mission has 8 untimed questions. Only the game saves choices and hints. A finished mission earns one launch charge and participation towards the Right scanner wing in Star Navigator. The chapter goal is 8 different questions in finished sets; hints and wrong answers count as participation, not mastery. Some craft systems link more than one chapter.

Levels change representations, clues and conditions, not just the numbers. These are practice formats, not validated exam-equivalent difficulty.

Using the feedback

Learning reports distinguish hinted answers from independent first choices. They consider up to 20 recent different, unhinted questions per skill and level, and wait for at least five before suggesting extra practice. Repeating the same question does not add evidence. Reports are practice evidence, not IQ scores, diagnoses, ranks or predictions of competition results.

Ask the learner to explain a drawing or check with objects too. Choose Explore or an earlier chapter when a step feels too large.

Sources & limits

The grade topics use SOF IMO Class 3 published topic syllabus as their primary reference. The SOF sample and CREST previous-year paper below informed representations and reasoning demands. Providers have different topic boundaries; their syllabi are not interchangeable.

Questions, diagrams, picture choices, hints and explanations are original Otterly work, not copied paper questions or publisher artwork. No Olympiad provider is affiliated with or endorses Space Academy. This is not complete exam preparation; follow classroom teaching and check the current official syllabus too. Independent educator review is still needed for difficulty and breadth.

Content and coverage notes. To report a confusing question, describe the grade, chapter, level and question on the contact page. Do not send children’s personal information.

Private, local saves

Game progress stays only in this browser, in three anonymous explorer slots. Clearing site data or closing a private session may remove it. Download a private backup from Help & saves; there is no cloud sync. The game checks saves before play and stops on save failures rather than pretending progress was saved.

These page examples never change a saved game. Game links carry question settings, not a learner’s answers. There are no names, school details, public profiles, chat, analytics or advertising SDKs in the game. Grown-up guidance · Privacy
