US
Worth 2 points before any premium square, and the lowest-scoring of the 96 — tied with 35 others.
US extends into 6 three-letter words, which is the 18th least extendable of 96 — tied with 3 others. That is the number worth memorising: a two-letter word is a place to put tiles, but a well-hooked one is a place to put them where the board stays open.
Every hook
- B→BUS
- J→JUS
- M→MUS
- N→NUS
- P→PUS
- E→USE
Not all of them are equally reachable, which a bare count of 6 hides. US hooks on 6 distinct letters, and the ones you are likeliest to be holding are E (60% of opening racks), N (36% of opening racks) and B (14% of opening racks). The rarest is J, at 7%.
How often you can actually play it
Out of an opening rack, 5.81% of the time you hold the letters for US outright, the 28th least likely of 96. Counting a blank as whichever letter is missing lifts that to 11.01%, though spending one of the two blanks on a two-letter word is rarely the play. Exact hypergeometrics over the 100-tile bag, not a simulation.
