Tromino

A tromino is a type of puzzle piece that looks like a small square with one corner missing (it kind of looks like the letter L). In order to play with tromino pieces, you need to arrange a bunch of them together to make a bigger square or rectangle shape. The challenge is to make sure that each tromino piece is touching at least one other tromino piece, and none of them are overlapping or going off the edge. It's like putting together a big jigsaw puzzle, but instead of lots of little pieces, you just have a few trominos to work with. It can be really tricky to figure out the right combination of trominos to make the shape you want, but once you do, it's very satisfying!
