Puzzle 79 (Island Line Nurikabe)

This is a Nurikabe variation inspired by Palmer Mebane's Line Nurikabe.

Rules: Standard Nurikabe rules, except that there may not be four consecutive white cells in a row or column. (Equivalently, you can not overlay an I tetromino on any island cells.)

  1. Wow, this puzzle was great! The variation led to a number of fun deductions, one of my favorites being gur oernx-va jvgu gur fvk, and it fit very naturally with the standard nurikabe ruleset.
