Which Tile Completes the Grid?

Explanation

Top Community Solutions The following explanations were selected from Reddit as the strongest community solutions for this puzzle. Each approaches the pattern from a different perspective while arriving at the official answer (C). 🥇 1. theflyingpurplehippo This explanation treats each letter (L, R, and P) as following its own continuous path through the grid. Even when a letter is absent from a particular square, it is considered to rotate 90° clockwise as it progresses to the next position. Combined with the rule that every row and column must contain exactly one L, R, and P, this creates a single consistent rotation pattern across the entire matrix. The accompanying diagram clearly visualizes why the missing tile must be C. ⸻ 🥈 2. RomblerSan RomblerSan first identifies the letter sequence moving across each row as L → R → P, immediately showing that the missing symbol must be an R. The explanation then examines both diagonal directions separately. One diagonal demonstrates a 180° rotation between matching letters, while the opposite diagonal explains how the remaining orientations align by rotating toward the reference letters. Combining both observations leads to a unique solution: C. ⸻ 🥉 3. Black_Bal Black_Bal focuses on the relationship between consecutive rows. The first symbol of each row is obtained by rotating the second symbol of the previous row by 180°, the second symbol comes from a 180° rotation of the previous row’s third symbol, and the third symbol is produced by a 90° clockwise rotation of the previous row’s first symbol. This systematic row-to-row transformation consistently produces C as the missing tile.
