15 Triominoes (Posted on 2016-07-26) Difficulty: 3 of 5
A tiling is said to be fault free if there are no straight lines which can split the tiling without intersecting a tile.

Two L-triominoes trivially form a fault free tiling of a 2x3 rectangle.

Find a fault-free tiling of a 9x5 rectangle using 15 L-triominoes.

Horrible stuck key!

This is the basic block I used to solve 'Tiling Trial' some time ago. Apparently it can also be done with 11 tiles.
