After cataloging all tiles in the image, the set contains 27 unique tiles from the 28 standard double-six set. The missing tile is the 6-0 (blank-six).

The excluded domino is number 2 and 1

By systematically checking all 28 possible dominoes in a standard double-six set, I identified 27 dominoes present in the image. The domino [2, 4] is the only one not shown. I verified this by scanning through all dominoes with 2 on one end (0-2, 1-2, 2-2, 2-3, 2-5, 2-6 are all present) and confirming that 2-4 is absent.

After systematically cataloging all 27 visible dominoes in the image, I identified each tile by its pip counts. A standard double-six set has 28 tiles. By checking all combinations from [0,0] to [6,6], I found that the tile [0,1] (or equivalently [1,0]) is missing from the image.

All other domino combinations from 0–6 are visible in the image except the double-six tile (6|6), which does not appear.

I systematically identified all dominoes in the image by counting dots on each tile. The standard double-six set contains 28 dominoes. After cataloging the visible dominoes, I found all dominoes containing the number 1 except for the [1,6] combination: [0,1], [1,1], [1,2], [1,3], [1,4], and [1,5] are all present, but [1,6] is absent. Checking dominoes with 6: [0,6], [2,6], [3,6], [4,6], [5,6], and [6,6] are all accounted for in the image, leaving [1,6] as the only missing tile.
Methodology Note
Each model receives the same domino puzzle grid. Models are tasked with identifying the missing domino using only visual clues from the grid. Their answers are evaluated without feedback or retries.
