ULTIMATE ALPHABEATER

Can you crack the super-tough Ultimate Alphabeater? Each grid number represents a letter – or black square. As in Alphapuzzle, every letter of the alphabet is used. But you have to complete the grid too! Use the given letters and black squares below the main grid to start. Alphabeater is ‘rotationally symmetrical’ – in other words it looks exactly the same if you turn the page upside down. Solution next Sunday.
