perplexus.info :: Shapes : 15 Triominoes

15 Triominoes (Posted on 2016-07-26)

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.

Harder case

I found a solution very easily. Then I found over a dozen more.

Not only is this puzzle simple, it is impossible to fail!

I was able to prove that any tiling of a 9x5 rectangle with L-triominoes must be fault-free.
