One liner of the week:
view f: layout for n 0 19 1[r:(random 19)+ n // 20 append[across]load rejoin["a"n": check on[a"r"/data: a"r"/data xor on show f]"]]
It’s a game: a line of twenty boxes appear, each with a cross on, the object being to remove all the crosses. Clicking on a box will toggle it and one other off and on. Sometimes the line is easy to clear, and sometimes not.
