The purple highlighted square is missing the number 7. The red highlighted 7 eliminates one of the empty tiles. One of the remaining two empty tiles must be the 7. Since they are all on the same row, no matter which one it is, nothing else on this row can be a 7. The gray highlighted square below is missing the numbers 3, 5, and 7. The pink highlighted 3's and orange highlighted 7's eliminate one tile from being either 3 or 7. That tile must be a 5. | |
