Tray — click to select, drag onto the board
Clues
How to play: every clue is a fact about the finished board. "Same piece" cells always end up covered by the
same piece; "different pieces" cells (always neighbours) always end up covered by two different pieces; an "edge/corner"
clue tells you a piece touches a specific side or corner of the board; a "given" clue tells you outright which piece
covers a cell. Click a piece (in the tray or already on the board) to select it, then Rotate/Flip it, or drag it onto
the board. Drag a placed piece back over the tray to pick it back up. The puzzle is solved the instant every cell is
covered and every piece sits in its one true spot — clues alone are always enough to work it out, no guessing required.
