What you see: the figure changes place. Behind it: progression on position.
Start here — one guess
Look at this for 20 seconds. What goes in the empty cell?
The tell: one small marker is in a different spot in each cell. Everything else stays still. Follow the marker's path and you've found the rule.
The family in one sentence
Movement: a marker changes position across the cells; nothing else changes.
One marker — a dot, a small shape — steps from place to place. The shape itself doesn't turn, grow, or recolour. Only its position moves. Your job is to follow the path and say where it lands next.
A marker stepping along a straight path, one place per cell — the figure stays put, the position moves.
What Movement looks like
- One marker (or two) changes position cell to cell. Everything else is constant.
- The path is the rule. The patterns differ only by what path the marker follows:
- Translation — the marker slides in a straight line, often wrapping to the other side.
- Orbit / position cycle — the marker steps around the perimeter, clockwise or counter-clockwise.
- Position-Latin — the marker visits each position once per row and once per column.
- Bouncing path — the marker moves until it hits an edge, then turns back.
- Accelerating step — each move is one place longer than the last.
