Hidden Tile Patterns — What Is Under the Mat?
Lesson 1 of 2
Tile-and-mat questions are a Selective spatial staple: four identical tiles in different orientations, with the centre covered — deduce what is hidden, not what looks plausible.
Hidden-corner tile puzzles appear regularly on Selective TS — near-certain marks when you compare visible symbols on each tile instead of guessing from the options.
The examiner checks whether you can identify the identical 2×2 tile, match symbols across the four orientations, and read off the four hidden inner cells without contradicting any visible symbol.
A 4×4 design is built from four identical tiles. A mat covers the four inner corners (one corner from each tile). Four 2×2 answer grids (A–D) show possible hidden patterns.
Best approach: Pick one fully visible tile and list its four cells. Match symbols on visible corners across the four quadrants to fill each hidden cell. Eliminate any option that disagrees on even one symbol.
