Draw fences along the grid lines so that every piece has exactly five squares — a pentomino. There are twelve pentomino shapes, named after letters: F, I, L, N, P, T, U, V, W, X, Y and Z.
Two pieces of the same shape may not share a side (a turned or flipped shape counts as the same). A letter in a square tells you the shape of the piece that square belongs to.
Shapes can repeat, as long as twins never touch. Corners and letter clues are the best places to start.
Split the grid into pentominoes — five squares joined side by side — so that two pieces of the same shape never touch, using the letters as clues.

Yes — as long as the two pieces don’t share a side.
Yes — an L and a mirrored L are both L.
Yes — every puzzle here is checked to have exactly one solution.
Open the Pentomino Regions Solver, type the letters and press Solve.
