But that's what I mean : LION and TOOK were a clash in the old grid but LOON and TOOK are not a clash in the new grid. In the new grid we have 4 new clashes and one old clash but where is the sixth one?
OK, I'll accept Kilgore Trout and Gem94's explanation. Thanks both of you. It's just a shame there couldn't have been six new clashes in the new grid. Very difficult though, I suppose.
Time to get stuck in(to) 4274!
