LO
Worth 2 points before any premium square, and the lowest-scoring of the 96 — tied with 35 others.
LO extends into 7 three-letter words, which is the 26th least extendable of 96 — tied with 7 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
No letter in front of LO makes a word.
- B→LOB
- G→LOG
- O→LOO
- P→LOP
- T→LOT
- W→LOW
- X→LOX
Not all of them are equally reachable, which a bare count of 7 hides. LO hooks on 7 distinct letters, and the ones you are likeliest to be holding are O (45% of opening racks), T (36% of opening racks) and G (20% of opening racks). The rarest is X, at 7%.
How often you can actually play it
Out of an opening rack, 10.47% of the time you hold the letters for LO outright, the 34th likeliest of 96 — tied with 4 others. Counting a blank as whichever letter is missing lifts that to 17.07%, 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.
