About pentominoes

What are pentominoes?

A pentomino is a shape of five squares joined edge to edge. There are twelve of them, named after the letters they look like: F, I, L, N, P, T, U, V, W, X, Y and Z. In this puzzle you use every piece you are given to fill a frame with no gaps. The pieces may be turned and flipped over. When they fill it without overlapping or sticking out, it is solved.

What is a pentomino?

A shape made of five squares joined edge to edge. Counting a shape and its mirror image as one, there are twelve. All twelve together famously fill a 6×10 rectangle and others exactly; the Oni puzzles use all twelve.

What is the Lounge Pass?

A subscription that takes the ads away in every game and opens everything that would need the Pass or a ticket. Here, all 310 puzzles. Without it, one ticket opens the next puzzles along a road (4 normal, 3 hard or 2 Oni; every easy one is free). ¥500 a month or ¥5,000 a year, tax included, with a 7-day free trial the first time. The first 100 founding members pay ¥300 a month or ¥3,000 a year, for as long as they keep it.

Does every puzzle have one answer?

No. Any way of filling the frame with no gaps is right. The harder the puzzle, the fewer ways there are, and the harder they are to find.

Can I see the answer?

While you play, a hint shows where one piece goes, one at a time. If the frame can still be filled around the pieces you have placed, it shows you the way on from there. You can use up to half as many hints as the puzzle has pieces.

What happens if I go wrong?

You are not told on the spot. A piece will not stay where it sticks out of the frame or lies on another piece: it goes back to where it lay on the table. When every piece is in and the frame is full, it is right.
