How to play

  1. Read the detail to compare

    Each search names the feature to inspect. Begin with a 4×4 field, then move to 5×5 fields with closer differences and more directions.

  2. Look past the distractions

    Frames and whole-symbol directions can vary. Find the one tile that breaks the stated rule. Tap it, or move with arrow keys and press Enter.

  3. See what changed

    A check marks the different tile; a cross marks a missed choice. Read the explanation, then choose Next search. There is no timer.

  4. Review the pictures

    After search 12, choose See results for your score, accuracy and stage totals. Review answers opens the first miss; numbered buttons restore any original board and a common-versus-different comparison.

Inside the game

What is Odd One Out?

Odd One Out is an untimed visual search with three stages of four questions. Each stage includes line tilt, ring-gap direction, line-end alignment and the position of a dot relative to an arrow. The first stage uses 16 tiles; the next two use 25. Angular and alignment differences get smaller, while balanced frame and rotation variations add distractions. Exactly one tile violates the stated feature rule, even though the other tiles need not be identical. Color is not needed. Position labels do not reveal answers; the task requires visual observation.

How your score works

Each correct first choice earns one point, up to 12, with no speed bonus. Completing search 12 saves your result; See results opens accuracy and three stage totals. Reviewing answers never saves another completion. New round discards unfinished answers. Random layouts and familiarity affect difficulty.

Example: a dot follows the wrong end

Arrows can point up, down or diagonally, with different outer frames. If almost every dot sits ahead of its arrowhead but one sits behind the tail, choose that arrow. A different frame alone does not break this rule.

Playing tips

  1. Mentally line up the pieces

    When a pair is rotated, imagine it facing the same way as its neighbor. Compare the ends of the two lines, or the dot against the arrowhead. The last stage uses closer angular and alignment differences, so a careful second look can help.

  2. Read the feature

    Follow the named detail rather than treating every frame difference as an answer.

  3. Compare local relationships

    For rotated pairs, compare the relationship inside each tile instead of its overall direction.

  4. Inspect a missed detail

    There is no speed bonus. Use the visual comparison in the review to inspect a subtle miss.

Questions, answered.

Results describe this game session. They are not IQ scores, diagnoses or clinical assessments.

Frames and orientations are distractions. Follow the feature named above the board: exactly one tile breaks that rule. For example, every dot but one stays ahead of its arrow, even when the arrows point different ways.

No. The puzzles use geometry and relative positions. Correct and missed choices also have check and cross marks.

The first choice is final for that question. Feedback identifies the different tile before you move on.
