Because there are 16 possibilities per cell, standard "pencil marks" (writing small candidates in the corner) can become unreadable.

Due to space, here’s the first row of a medium Hexadoku (symbols 1–G? No – proper hex uses 0–F): Use hexadecimal: 0 1 2 3 4 5

Row 1: 0 _ _ 3 | _ _ _ 8 | _ _ _ C | _ _ _ F
Row 2: _ 5 _ _ | 9 _ _ _ | _ _ 1 _ | _ D _ _
(…and so on for 16 rows)
