Are the puzzles in the Extreme Grade book from the archives of the Weekly Extreme Str8ts page?
Andrew Stuart writes:
They are all new puzzles.
Also, they can be solved (eventually) by the online solver whereas the Weekly Extremes are not. Those are picked from the few which the solver has no logic for. - [Del]

bought your new diabolical book. wished the puzzles were 1 per page to give one room to print numbers.
Andrew Stuart writes:
Noted. The pages are considerably bigger than our previous books as I wanted there to me more room for notes. But next time I'll go further. - [Del]
