Best Play Here
If you're holding all four tiles, no full-length words can be formed from this rack. Missing a letter or two? iao, iou, and oui are solid 3-letter fallbacks that stay valid across every dictionary here. Since A, I, O, and U don't repeat, you can also hold back a tile like the O or U and rebuild toward a different word next turn instead of dumping the whole rack at once.
