*Chessboard Tiling *explores tiling a chessboard with dominoes.

We could try tiling a chessboard with triominoes...

Each tile covers 3 squares, and a chessboard has 64 squares, so there will be at least one square left uncovered because 64 is one more than a multiple of three.

**Is it possible to tile every square except one?**

If so, which square(s) can be left uncovered?
